USB-C PD Controller STUSB1702 : SRC / DFP Role

[PPaul.3]

Hello,

I would like to use an stusb1702 on my custom board as source / DFP docking. I found git project for an stusb1602 and nothing for stusb1702. Can someone confirme to me that I2C Register Map is the same between both. Indeed I am not able to write in some registers (register based on git project for stusb1602) to configure my PD controller in SRC / DFP role.

For information i use a dc dc buck boost controller which delivers VBUS 5V for USB-C alimentation.

Sincerely,

Hello

May I know which STM32 you are using with stusb1702 ?

I guess that what you call 'git' is the stsw-stusb001x software packages (stsw-stusb0010 for stm32F072 for example)?

Using a 'source' project is such package should work with stusb1702.

Best regards
