I want to use the ATmega328 on my Arduino Uno board to clock a TDC1000 using the clkout bit of the ATmega328, but this requires fuse programming of the low byte. Can anyone tell me how to do this?
Do you have another Arduino? If so, check this video and you can set the fuses with AVRDUDESS.
Be careful: if you set the fuses the wrong way you kind of "brick" the chip, and depending on the mess, you can only recover with a high voltage programmer.
One advantage is that you can never ruin the chip with the fuses, just make it hard to reset to some defaults.
