CCS/BQ76PL455EVM: TMS570LS0432 interaction with BQ76PL455EVM

Ritul,

1) Are you using cells or a resistor ladder/simulator? If you are not using real cells, then the LEDs will not turn on when balancing.
2) Do you mean the module voltage? There is a module monitor you can enable, and sample. This is essentially a buffer that reads in the sum of cells. If you mean reading cell 1, cell 2, etc then you need to do this:

Data is stored in bFrame array in our example code. The cell voltage high byte is stored in one index, and the cell voltage low byte is stored in the next index.

For example, you want to read the cell 16 voltage of a module. Since the first byte that comes in is the packet header, you don't do anything with bFrame[0].

You can get the full two byte value of the cell voltage by shifting the high byte by 8 bits, and bitwise OR-ing the low byte:

( bFrame[1]<<8) | bFrame[2]

From there, you can multiply it by constant coefficient given in the datasheet. It is easiest to do that as a floating point number. So to fully calculate the cell voltage and store it in the variable CellSample, it would look like this:

CellSample = ((bFrame[1]<<8) | bFrame[2]) * 0.0000762951
