Hey everyone,
I’m using the ESPDUINO-32 for my UART Flow Control project, in which I communicate with a device via the GPIO pins of the development board using AT-Commands(8N1,9600bps).
I’m programming on VSCODE using the PlatformIO embedded environment for my unit testing, and that how my platformio.ini looks like:
I’m also running on an ESP-IDF framework, and I already had success with running a simple test on the embedded environment:
TEST_ASSERT_EQUAL(0,0);
Here is the structure of my project file:
The problem is that when I try to unit test my actual code, the development kit doesn’t give any output.
In the project, I’m using the gpio.h & uart.h libraries to config the output and input pins for the UART Flow Control.
I’m using for this project UART1 and the following gpio pins:
5-TX
4-RX
14-CTS
27-RTS
17-PWR
I should mention that I’m configuring the GPIO pins and UART port as follows:
uart_config_t uart_config =
{
.baud_rate = 9600,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = UART_HW_FLOWCTRL_DISABLE};
ESP_ERROR_CHECK(uart_set_pin(UART_PORT, TXD_PIN, RXD_PIN, RTS_PIN, CTS_PIN));
if (uart_driver_install(UART_PORT, RX_BUF_SIZE, TX_BUF_SIZE, 20, 0, 0) != ESP_OK)
{
ESP_LOGE(TAG1, "install uart driver failed");
uart_driver_delete(UART_PORT);
}
if (uart_param_config(UART_PORT, &uart_config) != ESP_OK)
{
ESP_LOGE(TAG1, "config uart parameter failed");
}
gpio_pad_select_gpio(RESET_PIN);
gpio_pad_select_gpio(PWR_PIN);
gpio_set_direction(RESET_PIN, GPIO_MODE_INPUT_OUTPUT);
gpio_set_direction(PWR_PIN, GPIO_MODE_INPUT_OUTPUT);
gpio_set_level(RESET_PIN, 1);
gpio_set_level(PWR_PIN, 0);
gpio_set_level(RTS_PIN, 1);
esp_timer_init();
Furthermore, I also used the menuconfig of the esp-idf framework in platformio to ensure I’m using UART1 for the HWFC:
When I try to unit test my code, here is monitor output:

If you don't see any output for the first 10 secs, please reset board (press reset button)

I just saw on Device Manager on my computer that I have another communication port:
I hope I was clear and explicit about my problem, would love for your help
