PANEL

Table of Contents

• Features Supported
• SysConfig Features
• Features NOT Supported
• Example Usage
• API

The Panel driver provides API to control I2C based display bridge driver present in the board. The display bridge can be a DPI/DSI based bridge that can convert DPI/DSI signals to HDMI output or any other output format.

Features Supported

• Configurable I2C address for bridge.
• Configurable I2C address for specific GPIO pin control for bridge.

SysConfig Features

Note

It is strongly recommend to use SysConfig where it is available instead of using direct SW API calls. This will help simplify the SW application and also catch common mistakes early in the development cycle.

• Option to specify I2C address for the bridge and bridge pin control.

Panel I2C Configuration

• Configuration for SII9022A bridge.

SII9022A bridge Configuration

Features NOT Supported

• DSI bridge.
