Firmware Suggestions for 17mm MTN-MAX lp Driver

Hi folks

I’ve assembled one board ( 17mm/22mm MTN-MAXlp - Low-Profile 1A-4A Programmable Buck Driver + 22mm MTN-MAX ) apart from the attiny13 - after much headache and a little cussing, I have this on the breakout board and the USBasp recognises it and I can flash to it successfully.

Now before removing it and more headache & cussing to get it on the the driver board - I’m looking into the firmware. I have looked through the firmware and how to flash guide (Guide: how to flash ATtiny13a based drivers (NANJG, QLITE, etc.) with custom firmware) and a few more.

My flashing requirements are relatively simple (I think): 3 levels - low, medium & high. Will most of the firmwares (that mention attiny13) work in this board?

Many thanks
