Re: [normal] [AVR-Chat] fuse bit problems!

In ponyprog (checked = programmed = 0) Erased fuses read 1 like any other eeprom location. I believe you'll need an external clock oscillator fed in the mcu, just an xtal won't do it. After you re-program the fuses, you can set any option you want. -carl At 04:39 AM 7/19/2004, you wrote:
