@agaletski @Omino870 @greekuser please stay on topic. This issue is here to track the progress on CMS32L052 support in cheali.

I believe that discharging circuit is never fully disconnected due to body diode in Q22 ([schematic](https://drive.google.com/file/d/0B1RXXTatsA1cb1R5NHM3MEtsakE/edit?resourcekey=0-YuNi1Kod3xXI4xazR8Gb_Q)) So it's not possible to discharge output capacitor without current draw from battery.

Attempting to discharge C22/C23 will always draw current from battery, which is connected right to it. Am I missing something? I can't see a reason in attempting to do so.

@stawel Maybe there is one reason to attempt discharging at the beginning. In scenario, when you are starting charging/discharging/..., output voltage is checked. Charger could measure just some residual charge...

Default calibration point may be way off. Try starting with higher range of your Ammeter, then dial the current down to 50 mA a then switch to some lower range...

I can confirm such behavior on my Turnigy 400Wx2. Waveforms below were observed when current calibration range is highlighted (Value nor whether charging or discharging does not matter.) and **start**...

Hi, Check the fan, if it spins on some PSU. It's 5 V fan, so even USB could be enough. Other thing could be damaged fan switching transistor. When you...

Hi, did you follow flashing guide https://github.com/stawel/cheali-charger/blob/master/docs/flashing.md ? During backup, has avrdude detected correct MCU? What are your fuse values? Squares on display are default state after power up of...

Also please attach avrdude logs/output as txt file or as code block.

@LeonHartStrife did you have any luck? Are you planning/willing to investigate it more?
