#181607 - dsPIC Responding to: ???'s previous message |
The dsPIC is a quite good chip if you know all the bugs in it.
What is your baud rate and your crystal frequency? if you use a crystal of 7.3728MHz you get 0 errors in baud rate and serial port should work fine. Otherwise you need to make small delay after you transmit each byte so that the stop bit doesn't get shorter and you get framing error. I designed 7 clocks for a customer few yeas ago, they communicate through serial port via RS-485. The clocks kept working for 2 years then suddenly they stopped working. I tested the transmitter board and it wasn't sending the data correctly. I replaced all components on it including the PIC and it refused to work. With same code I got it working by adding 1msec delay after each byte was sent. I wonder why? Mahmood |
