Re: 9 bit UART

I've found that when the UART gets a bad parity, at lest with the Arduino core, it just reads it anyways.

Anyone know how to check what the parity bit is?

9 bit UART

I've got a project that requires 9 bit data communications. The ESP32 only supports up to 8, however unsupported doesn't always mean it can't be done. There's a few options, but I'd like to ask if anyone knows what happens to data when a bad parity bit has been read. Can you still read the data or d...

9 Bit UART

Hello, I have a need to use 9 bit communications with the ESP32. 1 start bit, one stop bit, and 9 data bits. ESP32 supports up to 8 data bits, but it is possible to use a parity bit to send data. To send, we can reconfigure the parity "polarity" prior to sending each byte, in order to control if it ...
