| Really not enough info to guess. I use AVR Dragon and AVR Studio, so not familiar with your programmer. Can you verify or read back what was written to the chip? If the program is in the chip, you know chip is probably good, and need to look for another problem. Checked your fuse bits? I've only changed a few, but know you can do some messed up stuff if not set right. Is the chip being powered correctly? Checked your data sheet? Is your program actually working code? I/Os set proper? You need to post some pictures, schematics, and code if you hope to receive more then wild guesses or basic troubleshooting. You haven't even given a hint as to what your chip is suppose to do, or what sort of experience you have. Is the chip expecting an external oscillator, but you haven't provided one? | |

Really not to sure about it, need to think on it some. The buttons and resistors stick out as curious, not sure if it's right or wrong. I've only used switches. The program has an Rjmp instruction to a timer interrupt routine, which I didn't see. Maybe someone else will see the problem. If you still suspect the chip, try reprogramming it with some simple code (flash an LED) that you already know works. Not familiar enough with the PWM stuff to know if that's correct. | ||

Please mod and then test. Let us see, whether it functions provided your software is correct.
