Re: Parity on the RC controller

I just did a quick search in the PIC18F8722 (the microcontroller in the RC) data sheet to check the specs on the serial port. I learned that the Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) on the microcontroller does not support a parity bit in hardware, although one could implement parity functionality in software.

Thus, if you really need to have parity added to the RC serial ports, this would need to be added in your software.

Then again, maybe somebody out there has already written the code needed to add serial port parity calculations / processing to Kevin's serial port driver? If so, I wouldn't be surprised if he'd be willing to add it to the master version of his code if it is sent to him for that purpose.
