Part Number:BQ27411-G1
Hi all,
We have a custom board with BQ27411-G1.
We are trying to read the device ID from BQ27411-G1.
Most of the time master fails to read the device ID.
Our procedure are as follows
Start , device address=0xAA, control reg1=0x00, subcommand 0x01 ,0x00, stop
delay 1S
Start, 0xAA ,0x00, repeat start, 0xAB, 1 byte read, stop
We captured the write and read data using logical analyzer. In firmware, We are giving 0xAB after repeat start But, read address is incorrect in captured data.
I have attached screenshot for reference.
write command
Correct Read
Incorrect read
We have tried FW_VERSION and CHEM_ID but problem remains same.
Am I missing anything on read command?
Regards,
Kayathri
