9-bit Communication on Arduino DUE

[anthonylimon]

Hello all, I hope you are doing well as you read this message.

I am currently trying to find a way to receive a total of 9 bits of data through serial communication with one of those bits being a start/stop bit, so that data can be continuously received. Although I am working on the Arduino DUE, I am open to finding out how to do it on other devices. I can be more specific if necessary.

are you receiving a synchronous protocol? have you more details?

Please post a link to a page or document that accurately describes this "9-bit" communication protocol.

I remembered the PIC24FJ1024GB610 had a 9-bit data mode

never used it though
probably some of the processors used in Arduinos have a 9bit -mode - be interesting to see if the libraries give accress to it

The ATmega328 (Uno, etc.) supports 9 bit UART serial, but the description given by the OP doesn't make much sense.

In a standard UART protocol, it is not possible to have the start or stop bit be a "data bit".
