    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

    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?
  3. Hello All, I am getting a make error when attempting to build the PMOD ESP32 driver in Xilinx SDK. I will attach a picture of the the error and my SDK flow. I included all the path directories for the console application folder in the C/C++ Build Directories. The problem is essentially that "XPAR_PS7_UART_0_DEVICE_ID" doesn't exist. Is it under a new name perhaps? Should I export "Main.C" to the "src" folder? Any help is appreciated! **This is the line of code that is giving me the issue** "#define HOST_UART_DEVICE_ID XPAR_PS7_UART_0_DEVICE_ID"
  4. Hey All, I am trying to make a simple IP block design in Vivado 2018.3 to test the ESP32 PMOD out using AT commands for data transmission. I will attach a picture of my current block diagram to this post. I am getting a critical error (reference below) that says the IP has a packaged board value of "digilentinc.com:cora-z7-10:part0:1.0" which is for the Zybo z7 board. My questions are: Q1)Will this design work regardless of this error, as the Zybo and Zed boards are similar and both run off the zynq-7 architecture? Q2)If the answer to Q1 is "no", is there a method of adapting this IP for the Zedboard? (I should be using the latest IP library from Digilent) [IP_Flow 19-4965] IP PmodESP32_axi_gpio_0_0 was packaged with board value 'digilentinc.com:cora-z7-10:part0:1.0'. Current project's board value is 'digilentinc.com:zedboard:part0:1.0'. Please update the project settings to match the packaged IP.
  5. Hello, I have purchased a PMOD ESP32 for evaluation with Renesas Synergy. I have installed the required resources from the renesas synergy pmod esp32 application note. I also have the sample project up and running on the target demo board (PK-S5D9). I am communicating with the module through Tera Term and USB CDC. I am able to communicate with the module, and the module responds to the "get_mac" command: The issue I am having is that the command line options for "scan" and "connect" do not work. The module seems to be hang, and nothing is displayed in Tera Term after about 10 minutes of issuing the "scan" or "connect" commands. For the "scan" command, I get an "OK" response, but no APs are displayed in Tera Term. send command to module module response The Tera Term output remains as the image below for more than 10 minutes, with no APs listed. For the "connect" command, I am able to set the provisioning (removed the SSID and passphrase from screenshots): Send the "connect" command: Logic analyzer capture: After more than 10 minutes, there is no "OK" response, and the Tera Term displays the same info: While there is no logic analyzer activity. What could cause this type of behavior? Did I miss something in the project configuration? Is anyone else experiencing this issue? I am using e2studio 5.4.0.023, SSP 1.3.3. The ESP32 module has been updated to version 1.1.1, using the flash download tools v3.6.4.
  6. This project could have a number of names... "Give your FPGA some WiFi", "Give your ESP8266 a performance boost" ... among others. The project works "out of the box" with the CMOD-A735T and the Adafruit Huzzah ESP8266 Breakout Board but if you don't own either of these you can still adapt the code to your needs. But you'll have to download the project and read through the material. CMODA7-35T_ESP8266_Demo_Release_0_8.zip
