I read the warning not to divide the clock by more than 32 when using 128khz clock but I think thay mean less than 32 because 128khz / 32 = 4000 and 1/4 of that is 1000. The stk500 only goes down to 1.21 khz and I can't reprogram it. Did they lie or is there a way to drop the stk500 low enough to program it at 128khz while the program running has prescaled by 32?
I am on a roll here, at that speed I am able to run at idle mode of 4uA wake up get an adc reading move the stepper and go back to sleep.
I thought about on reset put the prescale back to 0 and then put a 3 second wait time so I could escentially reset the chip for 1 second then take the power off and programming would be faster, will that work or is there a better way.
Before I snuff another chip I will have a cup of java and wait for a reply. I suppose high V programming is the only way to reprogram those now.
Ahhh Never mind , I read it wrong, it says no more than 16 times, 32 times or more will not allow additional isp programming, I better slow down a bit myself me thinks.
