Other Parts Discussed in Thread: BQSTUDIO, BQ27Z746,
I'm able to communicate with my BQ27Z746 via Raspberry Pi and its I2C bus. But I was having trouble with some commands, so I connected an EV2400 driven from BQStudio.
Now I'm more confused than ever! I specified 0xAA as the fixed address and 1746_0_01-bq27z746.bqz as the target. When I first click [OKAY} I can see it perform a set of reads on 0x55 (the un-shifted address of the BQ27Z746), but then it puts up a dialog:
When I click [OKAY], it continues, but the values read by BQStudio are incorrect and the read operations on the I2C bus don't make any sense (SCL is top trace, SDA is bottom trace):
It appears to be writing I2C address 0x0b (unshifted), and only clocking 10 bits or so. Not surprisingly, the data read by BQStudio is clearly wrong as well:
Any hints as to what's going wrong?
