Hello I have been trying to make my MCU work at 8MHZ or 12MHZ for my project but I cannot seem to make it work even when I change the fuses accordingly.
For the 8MHZ i changed the fuses like:
LOW = 0xE2
HIGH = 0xD9 ( I don't need JTAG)
For the 12MHZ low power crystal oscillator i changed the fuses:
LOW = 0xFF
HIGH = 0xD9
I used 2 22pF ceramic capacitors and a 12MHZ crystal in the configuration provided by the datasheet:
The moment I power up my PCB the program is not working on either 8MHZ or 12MHZ.I also changed the CPU freq in atmel studio to 8000000 or 12000000.
Does it need more power than the 5V I supply?
