    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 https://github.com/mitchellorsucci/PMODESP32 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

    Altium Files

    Hello, Yes, I somewhat anticipated this response. The company i work for would be interested in such a boot strapping design. If there is some NDA we could have signed, or some other recommended pathway than starting from scratch, I would appreciated. I have done this in the past with Spartan -3 design , and would like to avoid doing again very tedious stuff. Best Regards,

    Altium Files

    Hello, I am working with Arty A7 and Arty Z7 dev boards with various PMODS building up a platform for imaging readout. While these are useful getting started, I will soon need to roll out a board with some customized routing. I notice many of the schematics and design files are shared in pdf. Are any of these schematic/layout files avialble in Altium for boostrapping some of these custom designs off the open source boards? This would really help accelerate FPGA design projects. I noticed Altium has some open source daughter boards, but this would be a better solution. If these are not open source, please let me know, I may be mistaken. If there is some kind of availability, please let me know how to proceed. Thanks, Jerome

    PMOD NIC100

    Hello, I am working with arty A7 and arty Z7 dev boards purchased through your website. I have downloaded IP files from github . However I when I import into Vivado (2018.2) I am not finding the NIC100 PMOD . Several of the other PMODS are working and verified. However, I am not finding the NIC100 PMOD in the add IP , even after digilent library is imported. Can you send me to correct github location that contains this file?

    ESP32

    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?
  6. Hello, Thanks. Yes I am familiar with basic demos at this point and am trying to move onto more interesting projects. I have implemented this demo but it seems to be all written in vivado HDL, with which i have a fair amount of experience coming from ISE. I was looking for some additional resources for SDK side. But now that I consider, perhaps even the firmware that the ArtyA7 comes pre-loaded with is likely to be pure HDL. We can close this question. Thank-you for your attention, it is much appreciate.
  7. Hello, I am working through some of the examples for the Arty A7 device. The device seems to come pre-loaded with firmware, some simple reference design that makes use of UART, LED's and pushbuttons. Is there some project I can download to reproduce this reference design? I am planning to overwrite this in the future, but I also wanted to have a copy. Thanks

    ZedBoard PCAM

    Well Thank's for your support. I will be working on several other projects trying to get them up and running. I think this was important. One question that remains in my mind however, is how to determine if the drivers need to be imported from the ip_defs folder or not when working with various IP. It was not very straightforward, as several other IP were using "generic" and didn't seem to cause a problem. The two that we selected seemed somewhat non-intuitive. I am wondering when this kind of thing will come up again, and I will need to handle. Thanks again.

    ZedBoard PCAM

    Hello, Nice. Works. no 3.3V jumper necessary. For some reason the SDK was not populating the main.cc file with any of the driver information needed. Now when I have recompiled form start, the main.cc file comes back with much more data. I don't think I fully understand the source of the error. It could have been includes. But the project is indeed functioning now. Thanks!

    ZedBoard PCAM

    OK. I will re-run. While Re-reading the first line though this reminded me of another concern I had. It requests placing jumper on 3V3, however, no pins were soldered. Should I manually short these and remove the 2.5V jumper? If that 3.3V is used or powering camera, I am wondering if this could also be impacting. Please let me know. Meanwhile, I will continue to re-build.
  11. Ok. Will go ahead and pick up a couple of those for our team to develop with. I will still be looking to get the other demos working with the ZED, however, there seem to be several interesting projects that could be useufl for our end application using ArtyZ7. Thanks for your quick, clear, concise responses.
  12. I see. So is zed dead? I frankly don't see alot of activity on this board to use for reference designs. Many links are broken. Would you suggest Arty Z7 for zynq development projects as a more up to date development board? Another board? One project we have in the works will be driven by Zynq and would like to have as many examples with PMODS / peripherals as possible. Thanks, Jerome

    ZedBoard PCAM

    Hello, I have actually tried to do both. For C++ i wrote a similar 'Hello World' example to make sure it is getting compiled. Unfortunately, I am seeing Hello World, but I am not seeing VGA output on the monitor. Does this imply there is some issue with bitstream? BTW, this is Digilent Board with FMC PCAM adapter purchased online through Digilent Portal.

    ZedBoard PCAM

    Hello, Thank-you for that clarification. I must have skipped that when I was building the demo. As seen below, I have updated the folders, and the drivers are updated. I am also recieving "Hello World" over com port. Regardless, VGA signal is not showing up on my monitor. Any other suggestions ?.

    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,
