#84137 - soft UART Responding to: ???'s previous message |
Naveed are you aware that the '51 has a hardware UART
Craig, this is an example of where a "stop till original poster answers" function would be grrrrreat. On a 52, maybe some trick with timer2 can be found, but I am not sure... 1) I do believe I were right believing the original poster was PIC headed since the method is "standard PIC". 2) if not and (s)he actually is looking for a soft UART then a) search here, it has been debated ad nauseam and b) there is somewhere in the Cygnal forum http://www.cygnal.org/scripts/U...tion=intro a soft UART that uses the PCA and when I saw that one I thought "if you HAVE to use a soft UART, that's the way to go". Anyhow, I recommend against soft UARTs in most cases since they either make all other interrupts have strange latencies or do not work very well. It is so much easier to either use a FIFO UART (philips have a few 1,2,4 UART chips) or IIC link to a LPC. Erik |
