DSI Usage

Tip

This tutorial uses Raspberry Pi 4B as an example.

Notes

• It is recommended to use the bookworm version of the Raspberry Pi system.

Raspberry Pi System

• Pre-packaged system images are available here, which have been tested for DSI screen display and touch functionality.
• Note: Screen configuration is required. System Images

Raspberry Pi 5 with MIPI

Tip

The FLY_MIPI is an adapter module specifically designed for the Raspberry Pi 5, allowing direct use of DSI and CSI devices through the adapter.

Raspberry Pi 5 with MIPI Wiring

Note

• The DSI and CSI interfaces on the Raspberry Pi 5 are now renamed to MIPI
• The MIPI interface can be configured to directly use CSI cameras or DSI screens
• Please pay attention to the direction of the gold fingers

• The Raspberry Pi 5 now has two MIPI interfaces. When viewed from the front, you can see labels 1 and 0 on them.

DSI Screen Wiring

• To use interface 1, configure the screen as follows:

dtoverlay=vc4-kms-dsi-7inch,dsi1

• To use interface 0, configure the screen as follows:

dtoverlay=vc4-kms-dsi-7inch,dsi0

• Please note that the camera model needs to be configured according to your purchase. This tutorial uses the imx219 as a reference.

• To use the left MIPI interface, configure the camera as follows:

dtoverlay=imx219,cam1

• To use the right MIPI interface, configure the camera as follows:

dtoverlay=imx219,cam0
