I would like to read the Vbus Voltage the TPS65986 sees via the I2C bus.
The bus access is running, I can read and write 4CC commands and other registers without problem.
When I set up the desired channel I want to read on register DATA1, I can write DATA1, then read and see that what I wrote is correct.
I can then send the 'ADCs' command to CMD1, and it clears to all nulls, which means that it recognized, and executed the command.
When I now re-read DATA1, it still contains my channel select information, and is never updated with the ADC results.
Behavior is identical whether I try to read die temperature or VBus Voltage.
What am I doing wrong?
I don't find any other things in the docs that I should have to enable. The Status register (0x1A) is properly reporting VBusStatus bits 21:20
I don't find any ADC enabling or configuration capabilities anywhere, including any implementation of the different operating modes described in the TPS65986 Data Sheet section 8.3.17.2, 3, 4, 5
Version register 0x0F reports that I am running firmware version 1.17.2
