[SOLVED] Set Low Fuse Bit, Now Can't Program over ISP

@dc42 - I attached various screenshots of logic analyzer outputs. The file names are as follows:

  • RAW_SOURCE: the output of connecting the analyzer directly to Pin 9 of the clock source Arduino, which is running your code, through a 1.5K resistor.
  • XTAL1: The analyzer output on CKOUT due to connecting Pin 9 of source Arduino to XTAL1 pin on m328p through a 1.5K resistor
  • XTAL2: The analyzer output on CKOUT due to connecting Pin 9 of source Arduino to XTAL2 pin on m328p through a 1.5K resistor

I connected both the Arduino, m328p, and the logic analyzer to a common ground throughout these tests.

How should I proceed?

Thanks again!
