usb_pd_alt_mode_dp_dock

Overview

This PD example is a simple demonstration based on the MCUXpresso SDK PD stack.
The application use the shield dock board (om13790dock) to implement the DisplayPort alternate mode. It recognize attached video source (like: “the shield host board (om13790host)” or “PC”), and drive the displayer to work.

System Requirement

Hardware requirements

One Type-C shield dock board
One 9V DC power supply
Type-C Cable
One hardware for a specific device, for example: one lpcxpresso54114 board
Personal Computer or the shield host board (om13790host)

Software requirements

The project files are in:
<MCUXpresso_SDK_Install>/boards//usb_examples/usb_pd_alt_mode_dp_dock//.

The is Bare Metal or FreeRTOS OS.

Terminal tool.

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

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.
Download the program to the target board.
Power on shield dock board then power on development board.

Run the example

Download this program to the board.
Connect the displayer to the MinDP port (J2).
Connect one video source (like: “the shield host board (om13790host)” or “PC”) to the Type-C port (J1). For example: if the video source is PC, connect the shield dock board to PC with one Type-C cable.
The video source will recognize the shield dock board and the displayer works.
