  1. I just completed my first mini-project on my new Arty A7 (my first FPGA). ? On Windows 11 with Vitis/Vivado 2021.2, I have the OLEDrgb working. It's unlikely I did everything the best or most proper way, but it's working. If anyone is interested, I shared a walkthrough with all of the steps I took to get the OLEDrgb working on my A7. Arty A7 & OLEDrgb Pmod Walkthrough All suggestions on how to improve the implementation are welcome. I can update the instructions with any recommendations you may have. Thanks!

    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
  3. 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
