If that's possible, and you could provide some instructions to do so, I'll bet it would just be a matter of time before others hop on.

Well, actually, this thread used to be about development :). Just read a few pages back, Mr. @tpw_rules did a great job at reverse engineering firmware, dumping calibration data, and even prepared a demo firmware with an lcd driver using cubemx. I tried to continue development, but cubemx and C is just not my thing.

Oh great! I totally missed that one (here: https://www.eevblog.com/forum/testgear/eevblog-121gw-multimeter-firmware-details/msg1418335/#msg1418335)
I don't have a lot of time for doing serious things for this, but I will have a look at it.

I have never used cubemx, but I have done stm32 C development with atollic.

And I hadn't even heard of ChibiOS. Can you share what you have so far?

hammy:
Third call for release notes and clarification about the version number.  ???

Some DMM are already shipped with firmware version 1.54? Is this confirmed?  :-//

Terry01:
I received mine today with 1.54 on it. Bought new from Welectron on the 15th. So.… confirmed  :-+

gdewitte:
And, again, could someone please enlighten us regarding firmware versions? What's going on?  |O
