Hello,
I am implementing a DRP device that is to be connected to a battery.
I have this DRP example setup with the X-NUCLEO-DRP1M1 and a NUCLEO-G071RB. It is working with a 5V profile and a fixed 5V supply.
I have added a 9V source PDO in CubeMX, and can see it when I interface with the hardware through the CC lines, and now need to communicate to a DCDC to up the voltage from 5 to 9V.
I am wondering where in the code base to interface with a digitally controlled I2C DC/DC converter.

Any help would be appreciated,
Nate

hello @NMartin,
ST is proposing some shield with integrated DCDC for power delivery.
Have you seen this evaluation board ?
From there, you can download the code for the I2C control of the STPD01 programmable buck converter.
Does it help ?
regards,
Nicolas
