Re: replace stm32
Hi, I replaced the original opamps with OPA2227 and OPA4227, which results in less offset differences between the ranges. The tweaking of R22 I have done is to get 0V reading when i apply 0V to the input. The ideal value of R22 will be different on different devices because of the spread of toleranc...

Re: replace stm32
My DSO is working with the new firmware.
Thank you!
I have replace the 2 opamps by low offset types, and also tweaked R22 (271,5k) to get a 0V reading in every range with the input grounded.

Re: replace stm32
Hello,
I have also replaced the microcontroller, but I can't find a working download link for the 15001k firmware, can someone help me with this?
