I programed an attiny45 with the blink code just to practice as it was my 1st time doing it. Well it worked just fine. Now when i tried to program my final code on that same chip it errors out but i could upload the final code to a new attiny45. So my question is are attiny45 chips a 1 time use or is there a way to delete the old code and replace it with a new code?
