LCR-T4 transistor tester original firmware

LCR-T4 transistor tester original firmware

Bought cheap transistor tester from eBay and currently experimenting with firmware updates.

I was able to program it with this version of Markus transistor tester firmware:

https://github.com/svn2github/transistortester/tree/master/Software/trunk/mega328_T4_v2_st7565

To build, use a WinAVR programmers notepad, open Makefile and select Tools->Make all.

At first, was getting weir errors, but after adding msys-1.0.dll to \WinAVR-20100110\utils\bin everything built ok.

Before doing firmware experiments, I have made backup of original firmware, if somebody needs it, you can download it here:

I tried to reflash original firmware and it worked fine.

For programming I use my MiniPro programmer.
