Introduction
The
STEVAL-USBC2DP
adapter is a miniaturized solution with a USB Type-C plug and a DisplayPort receptacle that
implements the DisplayPort Alternate Mode of the USB Type-C and Power Delivery specifications for compatibility with the
®
VESA
Standard. The adapter allows you to extend the screen laptop equipped with a USB Type-C-interface onto any screen
with a DisplayPort interface. This mode enables computers, tablets, smartphones, displays and docking stations with the USB
Type-C connector to rout high-resolution A/V and USB data and power through a USB Type-C cable.
The
STEVAL-USBC2DP
is based on the high performance ARM
USB-PD certified software that negotiates the Alternate Mode for DisplayPort with USB Power Delivery (PD) Vendor Defined
Messages (VDM). An optimized discrete analog front end (AFE) and the embedded STM32 peripherals allow management of
the Type-C plug lines and USB PD communication. The integrated USB 2.0 controller and the ST USB 2.0 Middleware stack
running on the STM32 provide the Billboard Device Class support required by the USB Power Delivery standard, as well as the
device firmware upgrade (DFU) capability
X-CUBE-USB-PD
is compliant with the USB Type-C™ 1.3 and USB Power Delivery 2.0 and 3.0 specifications.

To facilitate programming, install a five-position header 0.100" (2.54 mm) through-hole connector on P2. Then, connect the P2 SWD pins (2, 3 and 4) to the equivalent ones of the ST-LINK CN4 connector of an STM32 Nucleo-64 board, and connect P2 pin 1 to ST-LINK JP1 pin 1. Remove both jumpers on the ST-LINK CN2 connector to allow correct SWD operation (refer to UM1724 on www.st.com... -
