Hello.
I used 4 cascaded BQ to monitor 20 cells.
I designed the board according the schematic diagram of the bq76pl536EVM-3 and the layout was almost as same as EVM-3.
The problem is my master chip can only communicate with the first BQ through the spi, the others do not respond to the address discovery and assignement algorithm.
In my design, the port FAULT_H,ALERT_H,DRDY_H and CONV_H were not used.And the CONV_H was connected to VSS.
Did I do something wrong? Could you give me some suggest.
Thanks!
