This is a commercial unit supplied with preprogrammed chip. There may be other projects available with hex file.

Check this projects with LCD if you need say:

LCD 2x16 2xVolt 30V 2xAmp 10A ATMega8

Why do you want .hex file, why not compile it yourself. This is very simple voltmeter, and would need only a few lines of code. the inputs have been scaled down by
0.0636. so just read in adc, volts and multiply with 1/0.0636 that will give you the input volts. just a 15 min project.

Uuuuh sorry my friends, I forgot completely to put link.

Yes that is web address which tanveerriaz give in his post #17

Only HEX firmware is published.

On that address you can find many many other nice projects.
