bq40z80从f081读取出来的各个原始值是当前的真实值还是cell gain 、pack gain 、bat gain的值
You need to take the actual voltage on calibration from the source using a DMM and then enter that into the calibration window in bqstudio to calibrate the gauge. Once that's done, the drift in the gauge reading at different voltages will be very small.
Then the voltage value I get from address F081 is the actual value of the voltage that needs to be calibrated. Suppose the actual value of the current voltage value is 3958, and the hexadecimal display is F76. Then why is the 2's complement code read by the program not F76?
