Hi Steve. Thanks again for all your time.
I forgot to add int the first post that the PIC that is having to do some foregroud task is the one that is receiving the data. (sorry )
As for what I understood from the datasheet, and please correct me if I'm wrong, the USART can receive two full bytes berore you have to read them using the register. But that is only 140 us, not even enough for a single loop to be processed in the program im using. Is this correct???
By the way, what I am trying to do is a LED cube, with the LEDs multiplexed, so if the transmission takes long enough, there will be flickering in the leds.
Thanks a looooooot!!!
Manuel
