IMHO it would be a better scheme to have a regular timer interrupt on which you sample the states of the input switches. This would allow you to debounce the switches there,...

I include the following header to make the compiler happy. #include A

Hi James Firstly, I agree with Stu that you are lining up trouble for yourself by adopting a scheme which involves enabling interrupts within interrupts. That said, to answer your...

UART1 problem
If you can capture a trace of the signal that would be good. I can see nothing wrong with your code. It looks very similar to code I have for an AtMega32. I did think I had found...

UART1 problem
Hi Marcel Do you have an oscilloscope on which you could capture a trace of the waveform on the RS 232 line and let us have a look? And, I assume, your clock frequency is 16MHz? A

Can this be resolved at compile time?? "sumof()?"
Like this... (Couldn't resist) unsigned char AnArray[] = { 0x01 , 0x02 , 0x03 , 0x04 } ; unsigned char AnotherArray[] = { 0x11 , 0x22 , 0x33 , 0x44 } ; void AppendChecksum...

Can this be resolved at compile time?? "sumof()?"
Hi Andrew If you are unhappy to mess around with your existing program, you can take the ouput of that program and include it in the source of a simple new program. You then need...

UART1 problem
Sounds to me (if you think of the numbers in hex - 0xAA vs. 0xD6) that your baud rate is out by a factor of two for some reason. Just a guess. A

Board Lifting Mechanism
I would start by writing some code that "took control" of your board. By that I mean very simple code, at the level of flashing an LED regularly or similar. Next, (assuming you...
