STM32CubeMonitor-UCPD (STM32CubeMonUCPD) is a free software analyzer to monitor and configure USB Type-C and Power Delivery applications. It applies to any STM32 microcontroller running ST USB PD middleware stack. The development and the debug are simplified by key messages of USB PD protocol accessible through a convivial user interface. The developer can visualize in-live status and capability of any USB Type-C port (such as sink, source, or dual-role port), and USB PD packet messages during contract negotiation. The user can interact with the application environment by sending USB PD commands to the target board. The power or data role swap is executed in one click. The selection or the creation of new sink or source power profiles is made simple. The monitoring of analog parameters such as VBUS
is displayed in a specific measurement pane to facilitate the debug of the final application while the in-live debug trace pane allows visualizing message exchanges between the two ports.
