| Basic USB-C SINK |
| ################ |
| |
| Overview |
| ******** |
| |
| This example demonstrates how to create a USB-C Power Delivery application and |
| how to generate USB VIF policies in XML format using the USB-C subsystem. The |
| application implements a USB-C Sink device. |
| |
| After the USB-C Sink device is plugged into a Power Delivery charger, it |
| negotiates with the charger to provide 5V@100mA and displays all |
| Power Delivery Objects (PDOs) provided by the charger. |

| Requirements |
| ************ |
| The TCPC device used by the sample is specified in the devicetree |
| node that's compatible with ``usb-c-connector``. |
| The sample has been tested on :ref:`b_g474e_dpow1_board` and |
| :ref:`stm32g081b_eval_board`. Overlay files for the two boards |
| are provided. |
| |
| Building and Running |
| ******************** |
| |
| Build and flash as follows, changing ``b_g474e_dpow1`` for your board: |
