Need TI expert to answer this question,
I am now develop TI 27621-G1 gauge on our system.
I am confused with Control() (0x00 and 0x01) 2 pair- command and I try to read out device type(0x0621)
by sending
cmd1={0x00, 0x01,0x00) to get 2byte output
or using
cmd1 ={0x00, 0x01} and
cmd2 ={0x01, 0x00} to get device type
the all results are wrong (not 0x0621)
is any problem that I set the wrong command for it or any init procedure wrong before I do this query?
before query device type,
- i use seal/unseal to query and all get wrong result.
- i check GPOUT is init as HIGH.
- Slave address is 0xAA for write and 0xAB for read.
dont know any other problem to get wrong value
