Re: UART minimum baudrate????

Thanks for answer! The 5baud will be TX only for a single byte and then switch the baudrate to 9600 or 10400. So no interrupt pin, just send a single byte @ 5 BAUD and then switch. For a regular serial port on windows i'm using break signal. ESP32 can send break signal for a specified length on UART...

UART minimum baudrate????

Hello to everyone! I need to know what is the minimum baud rate for the UART port. I have an OBD communication board and i need a baudrate of 5 BAUD, 7O1 format. I don't want to use software bit-banging or timers. Is it posible to set a baudrate of 5, if the main CLK is 240MHz??
