Title: did i just kill my robot.
Post by: silent069 on June 28, 2008, 06:04:12 PM

ok so i decided to mess around with the programing on my $50 robot.  when it was turning from a dark corner to head towards light it was very jittery and would only turn inches at a time instead of a 90 degree turn ( what i was looking to do). So i hooked my bot upto the programmer, turned him on (holding it in my hand so it wouldnt drive off the table) hit program on avr studio 4 and everything wrote successful. First thing i noticed was the red led went out on the bot and it stopped moving. turned it on and off and nothing. I can still write to the chip and read its signature. So what went wrong? 

Update** ok thank god its not dead. after messing with the programmer ( had to do an update after doing this) i got everything working again!

When you program chips, they are held in reset.
They might also be held in reset while the programmer is connected. This is normal.
