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

jeroenmbed 4:ceee1eb7062e 28 *
jeroenmbed 4:ceee1eb7062e 29 * Program AVR chips with the AVR910 ISP (in-system programming) protocol,
jeroenmbed 4:ceee1eb7062e 30 * using an mbed. The version of Aaron Berk used a local file system, this version
jeroenmbed 4:ceee1eb7062e 31 * useses a python script to feed the data via a serial connection.
