Is there a page on differences between versions anywhere? Wiki? Something like that?
There's no side-by-side comparison but most major differences are mentioned in the readme file of the m-version. A short ad hoc list for the m-version:
- no ESR (yet) and Vloss (caps)
- just two languages included
- no support for software UART (serial output)
- no support for alternative LCD module pins (stripboard version)
- just ATmega168 and 328
- UI with selectable hold mode (wait for key press) and menu
- PWM tool (select from several predefined frequencies and change the PWM ratio in 5% steps)
- several measurements differ in some details
- completely different logic for diode detection
- low resistance measurement (kind of :-)
- Zener tool (4-30/40V) is selected via menu
- IGBT detection (if 5V are sufficient)
- readable source code with tons of comments
Should I make one? (not something I'd enjoy doing but it's info I would like to know anyway)
We would keep you busy :-)
