    Pmod OledRGB

    I think my question is general but i want to know how to initialize Pmod OledRGB using case when-statment i found some vhdl codes using this method but i cant understand it
  3. Looking at I see what appears to be template text lower in the page. Wondering whether that's intended to be filled out at some point?
  4. I am trying to use a Pmod485 (P/N 410-310) to connect an Arduino (TTL) to a motor controller (RS485). I am only using 1 Pmod485 and I am assuming I do need to short JP1, is this done just by sliding the blue cap over both pin headers? Also, the IC block diagram shows 2 separate GND (GND1 and GND2) but the module only has 1 GND available on the pin header. Does this mean both GND on the IC are connected together? pmod_pmod_pmodrs485_rm.pdf
  5. Hello, I'm new to this form, looking for some help with the Dual H bridge PMOD DHB1. I connected my power supplier to J4, my motors to J5 and J6. I have a custom IP that uses switches to drive motor speed with most significant bits of a duty cycle for PWM output at 2kz. I also have 2 switches connected to the DIR1 and DIR2 respectively. I also have button 3 connected to a reset condition to initialize code, inputs and outputs. To help debug, I connected the EN1 and EN2 output of the custom IP to the board LEDs to confirm that the signals are working correctly. I also checked the voltage at EN1 and appears to be doing what I expect. However, I do not have any motor actuation. I checked the voltage at the J4 = 8V, but neither J5 or J6 have any voltage differential between M+ and M-. I checked the sleep and fault pins they are both high, which is normal behavior as they are pulled low when in sleep or faulted state. Any advice on what I can do to find an issue would be appreciated. Thanks, Dave HBridgeTOP Hbridgecode (1)

    pmod esp32

    Hello, I am working with Artix A7 board, implementing various PMODs successfully. I am having some issue with PMOD-ESP32 unfortunately. The source files from a project off github (ESP32.c/ESP32.h) from as well as the included libraries (PmodESP32.c/PmodESP32.h) GitHub Project: I believe the following macros need to be re-defined in the ESP32.h file from github, however in XILINX project for Artix A7, there is a uart-lite that is connected via AXI and there is a uart connected to the ESP32 IP. I have tried to define both. When I define this as the uart-lite device ID, I get some output on console, but I cannot successfully connect to WIFI (which makes me believe the AT commands are being sent to AXI-UART , but not to ESP32 device uart). When I define uart_device as ESP device, nothing prints to console terminal. Please let me know if you have any suggestion. #define UARTLITE_DEVICE_ID XPAR_UARTLITE_1_DEVICE_ID #define INTC_DEVICE_ID XPAR_INTC_0_DEVICE_ID #define UARTLITE_INT_IRQ_ID XPAR_INTC_0_UARTLITE_1_VEC_ID When I try to use the PmodESP32.h / PmodESP32.c included with IP, I am also not able to succesfully communicate with device. I basically do the following ESP32_HardwareEnable(ESP32); ESP32_Initialize(ESP32, u32 UartBaseAddr, u32 GpioBaseAddr); ESP32_HardwareReset(ESP32); ESP32_SendBuffer(ESP32, u8 *buffer, u32 count); The commands i try to send are for connecting to WIFI and for configuring TCP, the functions return 0, which i understand means not succesful. I have reconfigure some of the functions from the github project to work with PmodESP32.c/PmodESP32.h files (the github project uses a UART only devicePtr, whereas the included PmodESP32 files have GPIO / UART structure). int set_wifi_mode(PmodESP32 * devicePtr, unsigned int mode) { u8 tx_buf[50]; if(mode > 3) { xil_printf("Mode %d is not supported for setting the WiFi mode\n\r"); xil_printf("Please Use Modes:\n\r"); xil_printf("\tNULL_MODE\n\r\tSTATION_MODE\n\r\tSOFTAP_MODE or\n\r\tSOFTAP_AND_STATION_MODE\n\r"); return XST_FAILURE; } sprintf(tx_buf, "AT+CWMODE=%d", mode); ESP32_SendBuffer(devicePtr, tx_buf, strlen(tx_buf)); send_n_clr(devicePtr); return XST_SUCCESS; } int get_current_AP(PmodESP32 * devicePtr) { u8 tx[] = "AT+CWJAP?"; ESP32_SendBuffer(devicePtr, tx, strlen(tx)); send_n_clr(devicePtr); return XST_SUCCESS; } int set_current_AP(PmodESP32 * devicePtr, char * ssid, char * pwd, char * bssid) { u8 tx_buf[100]; sprintf(tx_buf, "AT+CWJAP=\"%s\",\"%s\"", ssid, pwd); if(bssid != NULL) { int cursor = strlen(tx_buf); sprintf(tx_buf + cursor, ",\"%s\""); } ESP32_SendBuffer(devicePtr, tx_buf, strlen(tx_buf)); sendNLCR(devicePtr); return XST_SUCCESS; } int list_available_APs(PmodESP32 * devicePtr, char * ssid) { u8 tx_buf[100]; sprintf(tx_buf, "AT+CWLAP"); if(ssid != NULL) { int cursor = strlen(tx_buf); sprintf(tx_buf + cursor, "=\"%s\"", ssid); } ESP32_SendBuffer(devicePtr, tx_buf, strlen(tx_buf)); sendNLCR(devicePtr); return XST_SUCCESS; } ESP32.c ESP32.h PmodESP32.c PmodESP32.h
  7. Hi everyone ! I have little project to do :displaying an image on PMOD Oled in VHDL Language. I took the Nexys4 vhdl project and tried to make it run, i have an Basys 3 Board,so i've just replaced some constraints with mine on the Board,and it gives me Failed Bitream Write:W5,J1,L1 are not valid site or package pin .Why are they not valid pins,Do I need to make extra stuff to make it work on this Different Board ? I'll attach the constraint file below.Thank you in Advance. Nexys4_Master.xdc
  8. Hi, I recently purchased one of the LabVIEW Home Computing Kits with the Beagle Bone Black along with a PmodDA2 (I2C interface) and a PmodDA1 (SPI interface) from Digilent. My goal is to make low cost, LabVIEW based controller for an EV that I have built. I was able to get the BLINK VI to work without any issue once I realized what Debian Image would work with LINX. (As mentioned on this forum 8.6 is the latest). I am currently running 8.4 on my BBB but I cannot seem to get the LINX I2C interface to work. The code required for the PmodDA1 appears straight forward compared to other, more complex I2C Pmods. I have attached a screen shot of the LINX I2C Write error I keep getting. I get a similar error if I try to perform a read. I know that channel 2 is the only I2C channel available on the BBB according to a LINX pinout for the BBB I found on the LabVIEW MakerHub site, so the only issue I can think of is that I am just not sending the 17 bit slave address (0101000b) correctly. Any assistance would be greatly appreciated.

    Pmod wifi SDK problem

    Hi i'm using Vivado 2018.2 + Zedboard, my goal is to use the WiFiScan from the examples attached to Pmod WiFi folder. i have build the project in vivado section and exported it to SDK at that point i'm creating new application project, choose C++ project and select finish. i'm getting the following errors: flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 216 C/C++ Problem flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 216 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class TCPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class TCPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class UDPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'class UDPSocket' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'struct DNSMEM_T' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 145 C/C++ Problem flexible array member 'SMGR_T::rgPages' not at end of 'struct DNSMEM_T' HeapMgr.h ‪/proj_bsp/ps7_cortexa9_0/libsrc/PmodWIFI_v1_0/src/DEIPcK/utility‬ line 145 C/C++ Problem thanks for the help
  11. Hello, I am currently working on a university project where I want to record video frames using the Pcam 5MP and wirelessly transmit them via the Pmod WiFi to my laptop. I am using the Zybo Z7-20, Vivado 2017.4 and the Digilent vivado library from the master branch. My goal is to make a TCP server on my laptop and create a TCP client using the Pmod WiFi. In order to familiarize myself with the Pmod I have successfully implemented the following examples: HTTPServer and TCPEchoServer. In the TCPEchoServer example I have created a TCP client on my laptop using Python and I was able to send and receive simple messages like "Hello World", which were displayed in the serial terminal and echoed back to the TCP Client. I believe this shows that both HDL design and SDK project were correctly built. The SDK application is targeted to C++ and I do not have any compilation errors, just a few warnings. The HDL design is identical to the one in this post: However, I could not run the TCPEchoClient C++ example. In this case I used Python to create a TCP Server on my laptop and I tried to connect the Pmod TCP Client to this server. Every time I run the example the serial terminal outputs the following: Serial Terminal Output This demonstrates that the Pmod WiFi is able to connect to my WiFi network, but it cannot establish a connection with the TCP Server. The "state" does change to "TCPCONNECT" but the application gets stuck in the TCPCONNECT case, because the if statement " if (deIPcK.tcpConnect(szIPServer, portServer, tcpSocket)) " never becomes true. The szIPServer and portServer variables were set according to the DHCP IP allocation obtained from my WiFi router as seen in the screenshot below. const char *szIPServer = ""; uint16_t portServer = DEIPcK::iPersonalPorts44 + 300; // Port 44300 Where DESKTOP is my laptop and Unknown is the Pmod WiFi. Parameters which match the IP:port values were set in my Python script for the TCP server, which can also be found attached here. Initially I thought that there might be an issue with the TCP Server, but I have downloaded a TCP Client app on my phone and using this I was able to send and receive messages from my phone to my laptop. Therefore, my laptop does not seem to block any inbound TCP connections. I have also used a TCP Server app on my phone and modified the szIPServer and portServer variables in SDK to match the new setup. Once again, I was unable to establish a connection between the Pmod WiFi TCP Client and the TCP server on my phone. Is the TCPEchoClient example only meant to work with the TCPEchoServer example? I cannot test this as I only have one Pmod WiFi. I would really appreciate any help with this issue. Please let me know if I forgot to include other vital information about my setup. Kind regards, Daniel EDIT: I have added a few print statements in the "DEIPcK.cpp" file, more exactly inside of the switch(tcpSocket._classState) of the tcpConnect() function. These print statements show that my application cannot leave the ipsInUseW case. I have found that this case means " // we are in use, may not be establised, but just waiting to be established" but I am not exactly sure how to proceed from this point as I do not really understand what is happening. It also appears that the state of the TCP socket is always equal to 11 (tcpSynSent) which was obtaiend from "pSocket->tcpState". EDIT2: I have also managed to connect my Pmod TCP client to google's server as done by the user in this post: It seems like we both have the same issue where we cannot use the TCP Client to connect to our local servers.
  12. Hello, I've been trying for over a two months to make a project including the PmodWifi for sending data from PIR motion sensors to a computer with wifi. At fisrt I was working with Basys 3 board that I had but I undrstood that it doesn't have enough memory space. So I got Nexys 4 DDR board and tried using it there. Unfourtunatly I had some trouble with configuring the DDR so I reached some professional help from an engineer that works in the field. He gave me a new board, Zynq UltraScale+ MPSoC ZCU106, that he knows for sure how to work with and configure. We managed to generate bitstream and started working on the SDK by trying to use the TCPEchoClient example from the PmodWifi library ip (2019.1). We tried using this ip library first but it had errors so we switched to this one. We are currently working with Vivado 2017.4 because of what we learned that other versions have errors (flexible array member 'DHCPDG_T...). We got some other errors that we can't find any information how to solve. The first one is that from the beginnig when I just make a new application project I see an error in the bsp on the System.h file: 'XPAR_CPU_CORE_CLOCK_FREQ_HZ' undeclared (first use in this function) Final_Project_bsp line 73 C/C++ Problem This error happened also with the other library and to be clear, I didn't modify any of the files. After I edited the file (copy/paste from the TCPEchoClient example code) about 20 other errors showed up: undefined reference to `DEIPcK::begin()' /Final_Project/src line 186 C/C++ Problem undefined reference to `DEIPcK::periodicTasks()' /Final_Project/src line 244 C/C++ Problem ... undefined reference to `vtable for DEMRF24' AdaptorClass.h /Final_Project_bsp/psu_cortexa53_0/include line 61 C/C++ Problem I've been trying to make this thing work for too long, please help me finish this project. I'm attaching some screenshots of the project and the file. Thank you, Netanel.

    Hello, I am working on integrating ESP32 PMOD into a vivado 2018.2 project. I have imported DIgilent IP library into Vivado. When I place PMOD and connect to board, during compilation. It is actually a general message from the block design (See attached image). It apperas to me that this IP is for ArtyZ7? or some other Zync product? If so, is there IP available for Arty A7 or is this message to be ignored?

    Artix7 & ZedBoard

    Hello, My group has acquired the two boards Artix A7 and ZedBoard for developing some applications. I am noticing couple differences regarding projects and documentation. One such difference has to do with the reference base design. For Artix A7 I am finding the PMOD ports, and I2C, SPI, UART, Ethernet included in Board connections. For ZedBoard, very few peripherals are included in the base design I was able to locate. Question: For developing new applications for Zynq, can you provide some information regarding Zynq base desing. Is there more complete project for integrating HDMI / PMODS/ etc.. Does the Arty Z7 provide better support with respect to this feature? If so we may consider to develop on this board alternatively. I appreciate your feedback,
  15. Hi, I'm new to this and am considering buying these items chipKIT Max32 pmod OLEDrgb pmod JSTK2 My question is, how do I connect the pmod devices to the Max32? Do I need the following? Digilent Arduino PMOD shield I'm also considering getting a MPLAB Snap, would I need some sort of cable for that, like they mention in the video? Also, if I'd like to use what hardware do I need? Breadboard and cables?
  16. We are trying to communicate between two PMOD BT2 modules. We first configured one module as master and the other as slave using SM command in tera term ,then we searched from the master terminal for the other device and we got the MAC of the other device then we tried connecting to the device using the SR command but we didn’t get any response. Can you help us resolve this issue?
  17. At the description of the Pmod Step it says that it can drive both motors simultaneously. I want to know if it can drive them with different number of steps on each motor. So the Pmod STEP will be like an 2 in 1 driver or it can only drive identical the motors.

    PMod AD4 (16 bits/1MSPS)

    Dear all, Has Digilent stopped manufacturing and selling the Pmod AD4 (16 bits and 1 MSPs)? I can not find it online. Thank you. B.R Herve
  19. Hey all, First off, I apologize - I'm at work, now, with no access to the hardware, o-scope, etc. So all from memory for now, until I can get some time at home.... NOTE: All development being done under Xilinx ISE 14.7 WebPack. Target platform is an Opal Kelly XEM3005 (Xilinx Spartan 3E) Day 1: Wrote & sim'd Verilog to drive a PMODAD1 12b ADC. Seemed to work as planned. Day 2: Tried interfacing to an Opal Kelly XEM3005 (Spartan 3E) board with 3.3V logic & power. No joy. Funky stuff going on. Began troubleshooting. Day 3: Wrote code for Raspberry Pi Zero W (using WiringPi) to drive the AD1. Everything works as it should. Data reads work as close to perfect as I can ask for. Day 4: Continue troubleshooting FPGA - realize my constraints file is no bueno, and is assigning FPGA pins incorrectly. Fixed that. (So, reasonably sure that constraints file is copacetic) Day 5: Wrote code to drive a PMOD DA2 2-channel 12b DAC. Code Sim'd. Works well. Integrated into FPGA - code works well, DA2 works as advertised. Also works well with OK's FrontPanel - I can give a command from the PC, and the DA2 spits out the appropriate voltage. (This was another step to validate FPGA platform functionality & correctness). Day 6: Re-code and re-sim DA1 Verilog. Works as expected. Day 7: Integrate code onto XEM3005 - still no joy. Probe with oscilloscope: Power good - 3.3V, rock solid Ground good: little to no noise. Chip Select (CS) looks good - ~990kHz rate, normally high, Goes low for readout periods. Less than perfect due to being on a protoboard connected via a 6: cable. Serial clock (SCK) looks good - ~16MHz, only active during CS Low periods, high when CS is high (quiet time) DO and D1 outputs - constant low. A fair amount of digital noise. Sometimes, having a probe attached to D0 or D1 with the other probe attached to SCK or CS will couple noise in to the FPGA, giving me a noisy signal that is meaningless (except for the fact that it tells me my inputs are working - or so I think) It appears as though (bare with me - I'm an analog guy) the lines are heavily loaded - i.e., something is pulling the lines to ground. I see on the AD1 datasheet that the outputs are protected by 100 Ohm resistors, so this seems a potential (likely?) culprit (?) Not instantiating IOB's in my code, but those normally aren't necessary except to override defaults in the constraints file. Double- and triple-checked that the D0 and D1 ports are set up as inputs. Constraints file does not explicitly turn on Pull-ups or pull-downs. (LOGIC_3v3, IIRC) Recoded main fixture to move connections to different pins. No change in results - everything (appears) identical. Day 8: Just got home - did some double checking and disconnected the PMOD outputs from the FPGA: With the FPGA disconnected, the signals look pretty darned good: Took some quick measurements of the FPGA input pins - they seem to hava a constant ~0.75V on them with quite a bit of digital trash... This is clearly (I think) an FPGA setup problem.. So, here I am... Looking for clues. Anyone have any? Thanks in advance
  20. Hi there, I am in need of help communicating with my Pmod AD5 using the SPI on raspberry pi 3. I am pretty new to SPI and have troubleshooted and searched the web for solutions over the past week but have yet to solve this problem. Here are some of the steps that I have done: 1) managed to read values using the Arduino Library linked on the product page and with an Arduino UNO, by connecting VCC of Pmod AD5 to 5V (I am not sure what I cannot read anything when connected to 3.3V) 2) understood what SPI is about and what the Arduino Library is doing (or what I think was logical) - read through the whole AD7193 datasheet to understand the registers etc.. 3) extracted the outputs (Binary/hexa format) that the Arduino was sending to the Pmod AD5, understood them, and attempted to use them in raspberry pi with the spidev library but with no progress .. 4) tested by raspberry pi's SPI (they are enabled) using the same spidev library and successfully communicated and got values from a simpler ADC: mcp3008 using this 5) checked the wiring to ensure everything is intact and correctly connected For my application, I intend to read ADC values up at speeds up to 1kHz over 2 channels and hence have chosen this Pmod AD5. For testing wise, I have connected a potential divider across A1 and A2 on the AD5 and am able to read the voltage changes when using Arduino but not in raspberry pi 3. Here's my python code using the spidev on raspberry pi 3 (have connected to CE0): ####################### START OF CODE ################ import spidev import time spi = spidev.SpiDev(),0) spi.max_speed_hz = 50000 spi.mode=0b00 resp = spi.xfer2([0xFF, 0xFF, 0xFF, 0xFF, 0xFF]) print('Resetting...', resp) time.sleep(0.5) ##resp = spi.xfer2([0x08, 0x18, 0x00, 0x60]) ##print('Enable DAT_STA Bit', resp) ##time.sleep(0.5) resp = spi.xfer2([0x10, 0x00, 0x01, 0x10]) print('Set PGA Gain = 1, Buffer = 1', resp) time.sleep(0.5) ##resp = spi.xfer2([0x08, 0x18, 0x00, 0x64]) ##print('Setting filter rate select bits to 100', resp) ##time.sleep(0.5) ## ##resp = spi.xfer2([0x08, 0x98, 0x00, 0x64]) ##print('Initiate internal calibration, starting w zero-scale', resp) ##time.sleep(0.5) ## ##resp = spi.xfer2([0x08, 0xB8, 0x00, 0x64]) ##print('Full-scale calibration...', resp) ##time.sleep(0.5) while True: #choose channel resp = spi.xfer2([0x10, 0x00, 0x01, 0x00]) resp = spi.xfer2([0x58, 0x00, 0x00, 0x00]) time.sleep(0.1) print('data:', resp) ####################### END OF CODE ################ Here's what most of my output looks like when I run the code (kind of the same code regardless of whether I have or not have anything connected in A1/A2 - it is unreactive even when I connect my potential divider and change the potential): Resetting...

  21. Hello, I have combed through the forums but still have not found the answer I am looking for. I have the Arty board and Vivado 2015.4. I can create a project and I can select the Arty board in that process. I create a Block diagram on which to start building my 'circuit'. At this point I try two different ways to get a pmod port on the board: I click on the 'Board' tab and I find all the input and output ports (led, led_rgb, buttons, switches, spi, etc and Connector JA thu JD). I try and bring a JA onto the block diagram and get a message "Conn JA board component cannot be connected because no possible options to connect". Second thing I try is to click on 'Add IP' and select AXI_GPIO. Double click that and have the option to re-customize this block. Under 'Board Interface' is a drop down menu with , again, all the input/output items on the Arty board, but no pmod ports. I have tried this with and without bringing in the latest constraints file (from Github) with the same negative results. What does it take to get the pmod ports (Connectors JA-JD) on the block diagram? Switches and buttons and leds do move to the Block Diagram and they create an AXI block when they do. So what am I missing? Thank you for your time and help.
  22. Hi, My setup is using Avnet Ultrazed board with PMOD AD1. Also I am using Xilinx Vivado & SDK 2019.1. I am successfully being able to use 1 channel of the PMOD AD1. I am trying to use both the ADC channels on the PMOD AD1. As the PMOD libraries has no board support files for the Avnet Ultrazed board I went ahead and created a QSPI IP block to get a single channel working. I am having trouble getting the second channel working. Few doubts I have are: 1. For the QSPI IP block, should I use it in standard mode or Dual SPI mode. (I have set the data pins as MISO. Also selected the number of slaves as 1) 2. In the C code how do I switch between the 2 ADC channels as the 2 slaves are connected to the same chip select. I have set the slave select in initialize as --> XSpi_SetSlaveSelect(SpiInstancePtr, 0x01); 3. Should I use manual slave select or automatic slave select? --> XSpi_SetOptions(SpiInstancePtr, XSP_CLK_ACTIVE_LOW_OPTION | XSP_MASTER_OPTION | XSP_MANUAL_SSELECT_OPTION); Thanks!
  23. Hi I am trying to interface PMOD Wifi with PMOD ALS on a Digilent Zedboard. The idea is to display the ALS values on the HTML Page(default PinsPage.htm) every few seconds. I am stuck with the Application Code. I have checked the code which is used to read switches data to read the LED state and turn it on or off. Do I need to write code similar to that inorder to interface the ALS sensor and display its values on the HTML Page. Or is there any other method to achieve the same. Kindly suggest a way forward. I've attached the block diagram for reference. Thanks in advance.
  24. Hello, I'm a student and currently working on my final project including Basys 3 board and wifi pmod. I'm trying to get started working with the module to understand how it works. This is my first project working with Pmods. I've been using the Getting Started with Digilent Pmod IPs tutorials. I added the newest Vivado library including the PmodWifi IP and I bulit a block design with the MicroBlaze and other GPIO IPs. I followed the instructions of the tutorials and got to the part of validating the design, there I got a warning saying few of the wifi pmod pin are not connected. I've got a few other warnings and errors so I really don't understand what went wrong. If anyone know what the issue is and can help me, that would be awesome! Also I'm looking for an example project for wifi pmod using Microblaze to learn from. I'm attaching some screenshots of my project. thanks, Netanel.
  25. I purchased a PMOD-BT2 recently and since (according to your documentation) the SPI connector uses the same power as the regular PMOD connector, I though I could just connect it via the SPI header (not supplied), for programming. Strangely enough, the FPGA board (a Nexys4-DDR) would not power up. An investigation reveals a strange fact: according to an ohm-meter the power on the SPI header is reversed compared to your documentation. I would appreciate it if someone from Digilent could confirm this from the PCB schematics and update your documentation ASAP, as well as issue an errata, because connecting the power the wrong way round has a habit of blowing things up.
