Hi,

I am still new to much of this, but having a great deal of fun with Flowcode.

I tried to locate an input buffer for BOTH the RS232 ports on the 18F8722. Some PICs I have used have a 2 byte input and a 1 byte output buffer.

I could not find anything like that for the 18F8722. I did find an input register that looked like it was for RS232.

Does this mean there is a 1 byte input buffer for each RS232?

Thanks

Ron

Hello Ron

Yes you are right the datasheet is a bit vague about this. I would assume that the normal 2 buffer registers plus a value register is being used for the receive function. You could confirm this by submitting a question to the Microchip engineers.

Hi,

Just got the word from Microchip.

2RX and 1TX buffer PER UART

Thanks

Ron

Great thanks for posting your findings Ron.
