Arduino Uno or Pro Micro as an AVR ISP Programmer

I used an Arduino Uno and a Pro Micro with the ArduinoISP sketch to read and program other Arduinos and individual Atmel chips on a breadboard. This is useful when needing to recover an Arduino that needs a bootloader, or when using separate chips with AVRDude.

I seemed to need the Uno 10uF reset capacitor when using the Arduino IDE but not when using AVRDude from the command prompt.

AVRDude commands used on a Mac terminal - syntax of path names, COM ports etc may be different on other OS'. Refer to AVRDude usage guide for specifics:

General command structure: avrdude avrdude-config-file -P COMPORT -b 19200 -c avrisp -p CHIPNAME [FUSE READ COMMAND SAME FOR ALL]

Read high and low fuses from ATMega8515: /Volumes/GR_ROOT/avrdude -C /Volumes/GR_ROOT/avrdude.conf -P /dev/cu.wchusbserialfd1220 -b 19200 -c avrisp -p atmega8515 -U lfuse:r:-:i -U hfuse:r:-:i

Read high and low fuses from ATTiny26: /Volumes/GR_ROOT/avrdude -C /Volumes/GR_ROOT/avrdude.conf -P /dev/cu.wchusbserialfd1220 -b 19200 -c avrisp -p attiny26 -U lfuse:r:-:i -U hfuse:r:-:i

Read high and low fuses from ATMega328P on an Uno target: /Volumes/GR_ROOT/avrdude -C /Volumes/GR_ROOT/avrdude.conf -P /dev/cu.wchusbserialfd1220 -b 19200 -c avrisp -p atmega328p -U lfuse:r:-:i -U hfuse:r:-:i
