Hi,
Found this thread on google, and I completely forgot I was a member here
It seems ANY information regarding the operation, initialization, development of the USART in 'sync' mode is sparse to say the least.
Although there a few apps that require it (most would just use SPI) I'm trying to find a way to 'stream' bits continuously for wireless comms, at high speed. The speed I'm after is too high for bit-banging (and even for UART in async), so a hardware module must be used. I'm using the 16F628A as a prototype...my final design could use something a bit 'beefier' but I'm always up for pushing PIC's to their limits and it would make the development so much cheaper.
Anyone managed to see a scope trace of the output of the USART in sync mode? I don't have a scope, so its either debugging with LED's, which is depressing....or somehow working out if a continuous stream (bytes back to back, no stuffing/framing bits or delays) is possible.
If anyone has managed to 'solve' this enigma, I'd be very grateful to know the results.
