#90678 - overlooked Responding to: ???'s previous message |
If I do not set PCON.7, the serial port runs at 9600 Baud perfectly. However if I set PCON.7 (like in the code above), the port should run at 19200 Baud. This however doesn't seem to be the case. Furtermore, trying to configure other rates (e.g. 1200 or 2400 Baud ) fails.
I send data to the processor using a LAWN radio data link, which should be capable of sending data with a rate up to 19200 Baud. 1) the inability at lower rates indicate to me one of two a) the lawnmover ('v' not 'w') REQUIRE 9600 or will not move data or b) the T1 settings are wrong. 2) the inability at 19k6 can be due to what is mentioned in 1) or - as I have seen - because of too much work done in the ISR.
