MOSI and SCK set to output before Reset goes LOW #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I noticed that in the function "start_pmode()" MOSI and SCK are set to
output before RESET is active.
That would mean that if the program currently running on the target uC has
set the pins corresponding to MOSI and SCK to HIGH, then there would be a
very high current (from target AVR to programmer AVR) for a short time.

shouldn't reset go active (LOW) first?

Sounds good, changed in the svn and in avrisp.03.zip.
