Component tester
based on design from svn://mikrocontroller.net/transistortester/ Github: https://github.com/svn2github/transistortester
I made a few changes to the hardware for my own use:
-
A boost mode power supply for operating from 1 AA NiMH battery at about 45mA.
-
16x2 characters LCD module with backlight High/low setting
-
Power On/Off switch
-
I/O mapping is based on Markus's version with the following exceptions:
ATMega328 in TQFP with 2.5V reference at ADC6 and Battery voltage at ADC
PC3 - PC5 are unused and are available on connector JP2

Firmware: The files are from svn://mikrocontroller.net/transistortester/
I only make a few minor changes to match my hardware. They are included
here for completeiness and I am not maintaining them.
