ScratchMonkey Users Manual
February 14, 2016
ScratchMonkey is a sketch that turns your Arduino into a versatile programmer to burn programs onto a wide variety of AVR microcontrollers (MCUs).
What's New in Version 2.0
ScratchMonkey 2.0 features some fairly significant technical and architectural changes, notably:
- Thanks to the experimentation of João Paulo Barraca <firstname.lastname@example.org>, HVPP on standard Arduinos now reuses a serial port pin, so we no longer need an external shift register.
- Building on Leong Yu Siang's architectural idea, the code is now reorganized to separate the protocols from their concrete realization on the various boards used as programmers.
- Added support for programming the ATtiny4/5/9/10 family through the Tiny Programming Interface (TPI).
- Added support for status LEDs.
- Extended the STK500v2 protocol. avrdude will still be able to interface with ScratchMonkey through the regular stk500v2 protocol, but if it's patched to handle the extended protocol, ScratchMonkey will support status LEDs and TPI.
- Changed several of the pinouts. Please check the appropriate connection diagrams for details.
