Other Parts Discussed in Thread: BQ76PL536

Hi,

I am working on MSP430 Eval kit with 2 stacked  bq76PL536 EVMs in my project.

I have used slaa478 sample code from TI. I have got report of the cells from MSP430-EVM RS232 serial port.

but I have these difficulties:

1- The voltage pack has wrong value and it changes over the time.

2- some times I receive wrong voltage value for 4th bq-device, just for this device, some time 0V and some time 65XXX V.

I have install resistors and capacitors for improving communication and I have used shielded cables.

Thank you,

Alan
