i am programming this new atmega328P via AVR MKII and atmel studio , i successfully burnt the boot loader n then when i upload the blink program (with 1sec delay) it works fine on the arduino uno board but when i put it on the breadboard it does blink but extremely slow with a delay of min or so.
if i replace the chip with the one that came with arduino it works fine on the breadboard .
I am setting the fuses according to this video as extended: 0xO5 , high: 0xDE , low: 0xFF
if i set it to the fuse that the original arduino chip has then it doesnt blink at all .
i have a feeling its a fuse issue , on my bread board i have a 13.5Mhz crystal .
please note that the original chip works fine on the bread board so it cant be a hardware issue.
