Thanks to all who advised on this topic - it's been a valuable tutorial
for me.
I have the system working - the mysterious and seemingly random oddities
came from the programme freezing in a loop which was supposed to watch
for a signal from the ADC. (Write 100 times: "I will make use of
external interrupts.") After commenting this loop out and putting in
half a dozen calls to my "short delay" (loop of 10 nops), everything
started working just fine.
This:
while (PINC & _INT)
{
asm volatile("nop");
}
...I was polling the interrupt out of the ADC rather than hooking into
my external interrupt pin. Hmm...
Became this:
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
smalldly(); // Don't rush the ADC ;-)
Unfortunately, the electronics are now outside drying off; I hooked into
the pump, tried to prime it and both the controller and I got wet when
it backfired...
Cheers
