AlxDroidDevIt was here several times already mentioned.
Your tester is an identical copy of the original concept and is therefore compatible with the k-version (Karl-Heinz Kübbeler aka kubi48) and m-version (Markus Reschke aka madires) of the software.
Your dump (v1.17
) is probably useless, because the contents of the MCU is standard locked. Basically it does not matter, because the author of this software is Karl-Heinz Kübbeler. Therefore, without any modifications you can be applied directly his original software (directory
mega328_st7565_kit).
However, I recommend carefully studied the official
manual Note:
... It uses an 8Mhz crystal and all resistors are 1%. ...
Interesting, because all kits of this tester, that went through my hands contained the precise (0.1%) value of the test resistors 680 and 470k.
