Amperage Sensor Calib

[LeoLeo]

Hello,

I added an ACS758 unidirectional 50A sensor to my OSD. It puts out 60mV/A with an offset of 0,6Volts. I already moved the offset calibration in the GUI to full 255 just to get the amps reading to about 0V when the motors are shut off. But when flying, I get about 20% (not certain about linearity) to high readings. Where and how are these factors (60mV/A and offset 600mV) meant to be calibrated?

I also noticed that the voltage readings depend on the VCC supply voltage of the minim osd - is there a way around that issue? 

Regards,

Leo

Just saw the feature to calibrate amp reading has been removed in rev 540e9e97fb09 (btw: why are the rev numbers random numbers?). What was the reason for the removal?
