Writing specific bit stream to i2c

[setenv]

Hi,

After some strange behaviour of the DAC4716 chip, I want to try and reset it. The datasheet describes a way to do so over i2c using a specific bit stream. How can this be done using the 'standard' Zephyr i2c implementation? I currently use I2C0 twim to communicate with the DAC.

Hello,

The i2c_recover_bus() should do this for you, since this call will end up in:

Ok I didn't realise that. But indeed that looks like it does exactly that. It does not fix the issue, but that's something else. Thank you!
