Using UART0 and U0TXD U0RXD as regular UART on ESP32-C3

[vm__dm]

I need to use U0TXD and U0RXD as regular UART on ESP32-C3.
For testing, I am implementing a USB-to-UART bridge, from the physical UART to the USB-CDC one.
My test application is quite simple:

Code: Select all

#include <stdio.h>

#include <driver/gpio.h>
#include <driver/uart.h>
#include <freertos/FreeRTOS.h>

#define UART_NUM 0

FILE* usb_handle = NULL;

void uart_init() {
  uart_config_t uart_config = {
      .baud_rate = 115200,
      .data_bits = UART_DATA_8_BITS,
      .parity = UART_PARITY_DISABLE,
      .stop_bits = UART_STOP_BITS_1,
      .flow_ctrl = UART_HW_FLOWCTRL_DISABLE,
      .source_clk = UART_SCLK_DEFAULT,
  };

  // configure UART0
  uart_driver_install(UART_NUM, 1024, 0, 0, NULL, 0);
  uart_param_config(UART_NUM, &uart_config);
  uart_set_pin(UART_NUM, 21, 20, -1, -1);
}

void usb_init() {
  usb_handle = fopen("/dev/usbserjtag", "r+b");
}

void rx_task(void*) {
  uart_write_bytes(UART_NUM, "hello uart", 10);
  fwrite("hello usb", 9, 1, usb_handle);

  for (;;) {
    uint8_t buf;
    int read;

    read = fread(&buf, 1, 1, usb_handle);

    if (read > 0) {
      uart_write_bytes(UART_NUM, &buf, 1);
    }

    read = uart_read_bytes(UART_NUM, &buf, 1, 0);

    if (read > 0) {
      fwrite(&buf, 1, 1, usb_handle);
      //uart_write_bytes(UART_NUM, &buf, 1);
    }
  }
}

void app_main(void) {
  uart_init();
  usb_init();

  xTaskCreate(rx_task, "usb2uart", 4096, NULL, 1, NULL);
}

I connected an FTDI 3.3V USB2UART cable to ESP32-C3-devkitM-1 pins labeled TX and RX (GPIO21 and 20).
When I boot my device I see messages from the boot ROM (I don't need to disable them ATM) and then my hello message.
On the USB serial I also see the hello message.
If I send data to the USB uart I see the same echoed on the physical UART, but the opposite does not work. I also added a call to echo data back to the UART, but I still don't see anything coming out.
I suppose that is the UART0 RX path not working, because I see that uart_read_bytes always returns 0.
I checked with a scope on the pin and I see incoming data at 3.3V.

Here's my sdkconfig file:

I did some more testing. I took the serial echo sample and leave log output only on USB Jtag/CDC.
I could run it using UART 1 controller on pins MTMS/GPIO4 for TX and MTDI/GPIO5 for RX.
I changed UART controller to UART 0 and it still works on the same pinout (so it doesn't seem to be an issue using that specific UART controller).
I configured UART 0 TX pin on U0TXD/GPIO21, keeping RX as before (MTDI/GPIO5).
Then I moved RX to U0RXD/GPIO20 and echo is not longer working (no character is received on the UART).
There is something I need to do on the IOMUX layer to enable Rx path for U0RXD/GPIO20?
Pinout seem to suggest that those pins are "dedicated" to the UART and also those used by boot ROM, so I thought it was the suggested connection to be used for UART interface...

[vm__dm]

This thing is really driving me crazy.
I use the uart_echo example and I still can't receive any character on U0RXD/GPIO20.
I see output from ROM and the "hello" string, but sending character to that pin doesn't seem to lead to any result.
I also tried to use esp_rom to route that signal via GPIO matrix, but this doesn't seem to improve the situation.
If I change ECHO_TEST_RXD to 5 then everything work.
I am using an ESP32-c3-devkitm-1 board (only change is that I moved the two resistors to bypass the USB2serial converter on the board and connect USB signals directly to the MCU.
I connected an FTDI 3.3V cable to the board (only GND, TX, and RX are connected) to test.
I swapped both the board and the cable, to be sure that this is not a hardware fault.
I connected a scope to the pin and see the signal from FTDI cable to the RX pin, so issue seem to be on the ESP32 side.

Ok, I found the issue.
We re-wired the ESP32C3 board to bypass the on-board USB2UART (we wanted to test in a situation close to the final HW setup).
We moved R1-R2 to R3-R4, as suggested here:
https://esp32.com/viewtopic.php?t=21007
But we didn't remove R21 and R22 so the UART pins were still connected to the Cp210 converter. This didn't seem to be an issue for TXD but was preventing RXD from working (probably signal quality was impacted, even if it didn't look so bad during a quick check with an oscilloscope).
So, if you want to bypass the converter on that board is better to remove also R21-R22.

Hi, I am stuck also trying to use UART0 and U0TXD U0RXD as regular UART on ESP32-C3. It is a custom board. Where everything else works fine, connects to network, reads interrupts, and reads I2C line. For RS485 communication, I am using an "Auto direction control by transistor" scheme here.
https://iotips.tech/tag/esp32/

which is also used in a waveshare product. And works well with RP2040. I did a side by side comparison with an equivalent code using RPI PICO SDK.
https://www.waveshare.com/w/upload/0/02 ... -RS485.pdf

This kind of scheme where TXD pin is grounded is also in ESP's documentatation. Please see, The circuit C: auto switching of transmitter/receiver in the documentation

Screenshot 2023-06-08 at 02.00.04.png (377.2 KiB) Viewed 4155 times

, where TXD is grounded too:
https://docs.espressif.com/projects/esp ... /uart.html

Here is my schematic and code

Screenshot 2023-06-07 at 03.09.39.png (330.37 KiB) Viewed 4155 times

. I cannot get the RS485 device to respond on ESP32C3. Same Can you give me some leads please.
