Connection microcontroller and bq76PL536 EVM Board

Other Parts Discussed in Thread: BQ76PL536

Hello community,

I have a question about the connection between a microcontroller (TC1797) and the bq76PL536 EVM Board. The microcontroller is connected via SPI and sends a request to the cell 1 of the BQ76PL536. In response we get only 0x00 back. Maybe someone could help me with a C-code example of the first contact to the device?

 

Example of My Code: 

SPI_Write(0x00,0x3B,0x01); //CHANGE DEVICE ADDRESS TO 1

SPI_Read (0x01,0x03,0x02); //READING DATA FROM VCELL1 (REGISTER 03 AND 04 )
