Hello,
After I set the VOLTSEL bit and the number of cells to 12 I am not able to write any other settings to flash.
The bqStudio program shows the error: "a read of data written failed comparison".
However when I restore to previous settings (by reprogramming my old golden file - flash), I can change settings as normal. What does change internally in the bq34z100-g1 after setting the VOLTSEL to 1 ?
Additional info of my setup:
I'm using the bq34z100 EVM board with EV2300 I2C communication. On the board I swapped the obsolete bq34z100 IC to the newer bq34z100-g1.
My goal is to get the gauge working with 24V lead acid battery. I started simple using 1 single Liion cell, this works fine.
(For the 24V battery I did changed the jumpers to >5V on the EVM)
Thanks!
Leon
