Is there a limit to how large interrupt procedures can be (aside from the normal limits of flash RAM?)
Reason I ask, is because if I seem to make it too long (for example on my ADC interrupt, if I exceed about 10-15 lines of C code) the ADC conversion just seems to stop working altogether - I end up with zero on the conversion regardless of the actual input voltage.
I know you want to reduce interrupt code as much as possible to allow processing cycles for your main program, but I'm trying to figure out if it's just exceeding the interrupt's "size limit" or if I'm just programming a logic error somewhere.
Thanks
