DSI usage

tip

This tutorial uses Raspberry Pi 4B as an example

Note

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

Raspberry Pi system

• There are pre-packaged system images available, which have been tested for DSI screen display and touch
• Tip: Screen configuration is required System image

DSI Usage

• After the image writing is completed, enter /boot/config.txt and add the following command

dtoverlay=vc4-kms-dsi-7inch

• Save and exit

Raspberry Pi 5B using Mipi interface

Raspberry Pi 5 with MIPI

tip

FLY_MIPI is a special adapter module designed for Raspberry Pi 5, which can be used directly with DSI and CSI devices through the adapter.

Wiring for Raspberry Pi 5 with MIPI

Note

• The DSI and CSI interfaces on Raspberry Pi 5 are now called MIPI.
• The MIPI interface can be used directly with CSI cameras or DSI screens through configuration.
• Please pay attention to the direction of the gold fingers.

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

Wiring for DSI Screen

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

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

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

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

Wiring for CSI Camera

• Please note that the camera model needs to be configured according to the one you purchased. This tutorial uses imx219 as an example.

• 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
