Software UART between 2 PICs with different clock frequency

#1 Post by sagat11 » 12 Apr 2016 13:36

Does software uart work with 2 PICs with different clock frequency? I've search but i didn't found any answer. I also tried 2 pic16f877a one using 16mhz oscillator and the other 1 is using 4 mhz oscillator. Thank you sir.

Hi,

Which baud rate did you used?

Baud rate depends on the MCU’s clock and working conditions,
but if you can generate same baud rates on both MCUs, I believe you shouldn't have problem on establishing communication.

Best regards,

Uros

I use 2400 baudrate and it works. Thanks :)
