Hi,
I am using the CR since a couple of years, it is really awesome!
Recently I wanted to do something USB logging. I flashed the newest firmware release from Gibhub. With that release I now get every 100 ms or so (it is not very regular) a reading of 0.4 mA, even if no load is connected. Similar to uA range, where I get roughly every 100 ms some high value around 300-400 uA, although there is no load. Or a load of around 35 uA - as displayed with the old version (load is a MC with LIPO powering). I switched back to the old FW and got normal behaviour back. So something is off. I tried to fix that by setting the original calibration values but that did not improve things. Note this is with and without USB connected.
I am posting in this thread because I have apparently similar issues to pabigot which are not there with the 1.0 firmware. Felix, you mentioned that you also switched back. Is there a know issue, which will be fixed?
Also notably, when switching back to the original firmware the OLED worked. Then after powering off and on again it did not work any longer. Similar to what was also posted in this thread. I was able to fix it by putting a delay(1000) before the Wire().begin() statement in setup.
Thanks,
Stefan
