Hello!
My team is working on cell balancing a 4-cell lithium ion and 4-cell lithium polymer pack with the bq77910a and was wondering if there was a way to output the individual cell voltages from the '910 to a text file? We're trying to work on a GUI to show the individual cell voltages to show how the middle cells are depleted faster than the outer cells and explain how the cell balancing works for the chip. Our thought was to output the individual voltages to a text file and have Matlab read them to a programmed GUI, but we can't figure out how to read them from the '910.
It seems simple because if the programming of the chip is reading the voltage of each cell for the balancing function anyway, then surely it could output that reading to a file. Right? Or am I making a complex thing only seem simple?
Thanks!
