While skimming trough the UART driver documentation, I've noticed the esp_err_t uart_set_parity(uart_port_t uart_num, uart_parity_t parity_mode) function. Once the UART driver is configured and installed, is it possible to change the parity mode setting "on the fly" simply by calling this function, ...

I need to transfer frames of 9bits over UART (9 data bits + no parity + 1 stop bit). Having already checked, I see there is no native support for 9bit data frames on ESP32. However, I'd like to ask if the following is possible? When transmitting: 1. Construct the 9 bits that need to be transferred. ...
