- That's somewhat nebulous. So, looking at the code, I have no way of knowing whether the "default" hardware flow control pins are used for UART or not when the UART is in use. Can someone clarify?

Another situation of my application is that im using most of the GPIOs with none to spare,
the issue is when i try to start implement the uart,following the example i see the function to set the gpio pins i see that i am forced to set pins for rts and cts.
Seeing the example, i see this line:
Code: Select all
uart_set_pin(EX_UART_NUM, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE);
Code: Select all
esp_err_t uart_set_pin(uart_port_t uart_num, int tx_io_num, int rx_io_num, int rts_io_num, int cts_io_num)
can they be redeclared as outputs later? am i missing something?
