Tool/software:
Hello,
I am having an issue with obtaining consistent readings from the calibration mode. Specifically, I am attempting to get multiple readings of the Current Coulomb Counter to perform the cc current offset calibration, but the extracted value fluctuates between x00ff, x0001, x0000. I first believed that this was due to the data read falling on the update boundary, but the surrounding bytes do not seem like they are being updated. Listed below are the hexstrings associated with each value.
x00ff: 18 7A 02 1F 00 00 00 00 00 46 0D 00 00 00 00 FF FF 8E 0B 00 00
x0001: 18 A5 02 1F 00 00 00 00 00 4B 0D 00 00 00 00 01 00 8D 0B 00 00
x0000: 18 92 02 1F 00 00 00 00 00 46 0D 00 00 00 00 00 00 8F 0B 00 00
Given that the values are in little endian a jump from x0000 to x0100 is concerning, let alone x0000 to xff00. As for my sources, I am using the sluubd3e.pdf(technical reference for BQ78350-R1) with sections 12.2(Calibration) and 17.34(0x23 ManufacturerData()/CalibrationData()) being of note.
If anyone has any insight into this, it would be greatly appreciated.
