28 pin ATMega
Pimping out an Olimex AVR-P28 Dev Board

Synopsis: Alright,
“pimped out” might be a little bold...lets say we
“spruced up” an AVR-P28 dev board. A few weekends
ago I built about 8 ATMega8 proto-boards to go into
the hand sensors of the
speed timing system. In the process, I
spruced up a little Olimex AVR-P28 board so I could
flash the chips and also to test the code on the
dev board and use the dev board to test the
protoboards as well. Here’s a video of how that
looks if you’re new to AVRs or the Olimex AVR-P28
dev board.
In order to get serial data in and out of the board you need to tie a couple pins together. At first it may seem like an oversight that Olimex didn’t just have the serial port hooked to the serial pins of the ATMega socket, but like most things on an AVR, these serial pins can be used for other purposes, so it’s not a given that all people will use them for serial. For that reason, you need to connect it yourself. Here’s a shot of the underside of the board with a couple of wire-wrap size wires soldered to connect serial input and output to the ATMega:
