I have an AXON 1 and I have been having some UART troubles.
1) If I use just UART1 (the USB) it sends data just fine, but it won't receive it. I have tried putting all the original source code on (only commenting out all the timers because I get a badISR called error and constant resetting if I don't). Then I deleted the original control() and replace it with the following code:
temp=uart1GetByte();//returns -1 if no data present
if (temp == 'r')//if data received
The out put goes until it hits the uart1GetByte(), then it waits but never gets anything.
2) When trying to use one of the other UART ports I just get a bunch of "4"s displaying on the screen. I am using RS232 with the Axon "T" Pin to RS232 Pin 2, Axon "R" Pin to RS232 Pin 3 and Axon "G" Pin to RS232 Pin 5. This configuration also does not show any noticeable response to input. I am pretty user I have all my ports configured properly at 115200 Baud.
Any hits you can offer would be greatly appreciated.
