STM32G071B-DISCO USB-C Discovery kit
Introduction
The STM32G071B-DISCO USB-C Discovery kit comes on top of the STM32Cube™ as a
firmware package that offers a full set of software components based on a modular
architecture allowing each module to be used separately in standalone sink applications.
The STM32G071B-DISCO USB-C Discovery kit may be executed in two different modes
depending on the position of the switch: standalone sink mode, or spy mode. The spy mode
does not use the USBPD stack. In this mode, the protocol information on the CC lines is
decoded, and no protocol action may be triggered. But in the standalone sink mode, some
protocol actions may be executed.
In both modes, the UCPD block port 1 is used, and may give an example for a customer
application.
The STM32G071B-DISCO USB-C Discovery kit has been designed to run on
STM32G071B-DISCO (MB1378).
