Venice MIPI DSI / CSI

The Venice family of rugged and industrial Single Board Computers feature MIPI Display Serial Interface (DSI) and Camera Serial Interface (CSI) signals on many of the boards. This allows for displays and cameras or video input to the SBC.

There are 1000s of LCD displays from 5inches to 20 inches on the market and each may require a custom integration with the Gateworks MIPI DSI connector. Gateworks has pre-tested and pre-approved the following displays here

Venice MIPI DSI / CSI Software

Please note, a display of any kind needs a software driver for the chip used on the display as well as a software driver for the IMX MIPI-DSI controller. These drivers are not trivial and if a chip is on the display that doesn't have an existing driver for it, one will need datasheets and reference manuals to write the driver - this is not an easy lift and would require strong software expertise.

Please note this software effort has basically already been completed for our pre-approved and tested displays here

50-pin MIPI Media Connector

A 50-pin MIPI Media Connector is available on the GW720x/GW730x/GW740x with the following signalling:

  • 4-lane (4D+C) CSI (supports a maximum bitrate of 1.5Gbps on IMX8MM)
    • Allows for camera / video input to the SBC
  • 4-lane (4D+C) DSI (supports a maximum bitrate of 1.5Gbps on IMX8MM; up to 1080p60 display)
    • Allows for a LCD Display to be connected to the SBC
  • Bi-directional I2S audio
  • I2C
  • 4x GPIO

GW16136 RaspberryPi Camera and Display Adapter

This adapter plugs into the 50-pin MIPI Media header on the Gateworks SBC. The adapter brings all the DSI signals to one connector and CSI to another. The adapter was built in mind to be used with Raspberry Pi displays and cameras.

Additional Linux kernel driver support is required for various MIPI, I2C and I2S devices.

Purchase the GW16136 on the Gateworks shop: https://shop.gateworks.com/index.php?route=product/product&path=70_86&product_id=236

Raspberry Pi Displays

Not every Raspberry Pi Display will work out of the box.

Below are screens Gateworks has evaluated:

GW16145 MIPI Media Breakout board

This adapter plugs into the 50-pin MIPI Media header on the Gateworks SBC. The adapter brings all the signals to a 50 pin header that allows for a cable to be connected.

Additional Linux kernel driver support is required for various MIPI, I2C and I2S devices.

Connector used on the GW16145: Hirose DF20F-50DP-1V(56)

To make a cable that plugs into the GW16145, use Hirose DF20A-50DS-1C (Note also requires crimps)

Alternate Displays

Densitron MIPI Displays makes several MIPI based displays with touchscreen options. Densistron can also customize the display's adapter board for volume projects to connect directly with the Venice MIPI DSI/CSI connector. Please note these screens will require software driver integration as described here
