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 a dedicated adapter module designed for the Raspberry Pi 5. It allows direct use of DSI and CSI devices through the adapter.

Raspberry Pi 5 MIPI Connection

Important Notes

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

• The Raspberry Pi 5 now has two MIPI interfaces. Looking at it from the front, you can see markings 1 and 0.

DSI Screen Connection

• If using interface number 1, configure the screen as follows:

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

• If using interface number 0, configure the screen as follows:

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

• Please note that the camera model configuration depends on the one you purchased. This tutorial uses the imx219 for reference.

• If using the left MIPI interface, configure the camera as follows:

dtoverlay=imx219,cam1

• If using the right MIPI interface, configure the camera as follows:

dtoverlay=imx219,cam0
