Other Parts Discussed in Thread: BQ4050, TPS65987, BQ25703, BQ25703A, , TPS65981
I have a customer using the TPS65987, BQ25703, and BQ4050 similar to the TIDA-01515 but with only 1 USB C port. They are having issues with I2C on the TPS65987. They can communicate to the BQ4050 with no issues but are having difficulties on the BQ25703.
From the customer:
I2C seems to be able to read and write to the TPS65987 correctly. I can change parameters, write them and then read the changes back in debug mode. The one parameter I don't read back correct is the slave ID, always comes back as 0x00.
When I do the I2C address scan I see devices at both 0x22 (the TPS65978) and 0x6B (the BQ25703A). So the BQ25703A is responding
Thanks,
Nick
