Jeroen Voogd / Mbed 2 deprecated mAVRISP_Serial

A fork of mAVRISP by Aaron Berk. This version does not use a local file system to hold the AVR program. Instead it uses a serial connection to a PC and a python script to send the AVR program to the mbed.

Dependencies:   mbed

IT WORKS!!! I can now program an atmega328 with ISP via the mbed. No bootloader.

Who changed what in which revision?
