The STEVAL-USBC2DP is a compact Type-C to Display Port adapter solution with a USB Type-C connector and a DisplayPort connector, providing a comprehensive VESA® DisplayPort standard interface using the alternate mode of the USB Type-C and Power Delivery specifications.

With this adapter, you can connect a display with a DisplayPort interface to any laptop, tablet or smartphone, and use a reversible USB Type-C connector that complies with the Power Delivery specification. The DisplayPort alternate mode allows video data to be transmitted over the SuperSpeed ​​USB line on the Type-C connector, while the auxiliary channel (AUX) and hot plug detection (HPD) signals are sent over other Type-C lines. The high-performance ARM®Cortex®-M0 32-bit STM32F072C8U6 microcontroller negotiates DisplayPort Alt Mode via vendor-defined messages (VDM) according to the USB Power Delivery specification. The messages are transmitted over a simple discrete analog front-end (AFE) interface between the STM32 MCU and the USB Type-C connector via the Configuration Channel (CC). The STM32 microcontroller and embedded USB 2.0 controller running the ST USB middleware stack provide Billboard Device Class support required by the USB Power Delivery standard, as well as device firmware upgrade capabilities.
