Hi,
Thanks for the correction, maybe I'll add a picture gallery, as james38 already did in part.
(..)So firmware for 4410 and 4510 is the same as expected.
Model will be stored somewhere in flash or EEPROM, question is it easier to change that string or mod the FW to select that model number.
Thanks that you have already tested it, then I don't need to do it anymore, or maybe I should upgrade the ET4410 with this newer firmware anyway.
OK...
So one firmware for both models.
And very probably for all frequency types, whether 10kHz or 100Khz.
But it is only one chip, so the information must have been written to the chip somehow "before" or separately, in terms of who I am and which measuring frequency I output the highest.
Or there are two MCUs in the device, to make sure that this information is only available on the chip in the front board, I will swap the fronts with each other.
Interesting thing.
