Getting Started

Hardware Settings


For detailed instructions, see the appropriate board User’s Guide.

Please reference to the re-worked document for hardware settings.

Prepare the example

  1. For MCUXpresso, please reference to the MCUXpresso SDK USB Type-C PD Stack User’s Guide to make sure the SDK_DEBUGCONSOLE = 1 in project settings.

  2. Download the program to the target board.

  3. Power on shield host board then power on development board.

Run the example

  1. Download this program to the board.

  2. Connect the video source (like: PC) to the MinDP port (J2).

  3. Connect one video adapter (like: “Type-C to DisplayPort” or “Type-C to HDMI”) to the Type-C port (J1).

  4. Connect one displayer to the adapter. For example: if the adapter is one “Type-C to DisplayPort” adapter, connect displayer to the adapter with one DisplayPort cable.

  5. The video source (PC) will recognize the displayer and the displayer works.

  6. The follow UGREEN USB-C to HDMI/VGA device has one issue. If keeping the device connected with shield host board, then reset mcu board, the UGREEN device doesn’t work.
