     11'''This wiki page covers all hardware related information to the Venice MIPI interfaces. Software is also a very important aspect, and all software information is covered on the [wiki:venice/multimedia] page.'''

    1113Please 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.

     35The GW16136 !RaspberryPi Camera and Display Adapter connects to the GW720x and GW730x boards 50-pin MIPI Media connector and provides the following (see [https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf RaspberryPi v4 schematics for details]):
     36* 15pin Camera Interface with 2-lane MIPI CSI, 1x GPIO, 1x I2C (MX8MM I2C3)
     37 - MIPI_GPIO4 is IMX8MM GPIO1_01
     38 - Note the pin numbers on the connector silkscreen are flipped
     39* 15pin Display Interface with 3-lane MIPI CSI, 1x I2C (MX8MM I2C3)
     40 - MIPI_GPIO3 is connected to IMX8MM GPIO4_01 via 1Kohm
     41 - MIPI_GPIO1 is connected to IMX8MM GPIO4_04 via 1Kohm
     42 - Note the pin numbers on the connector silkscreen are flipped

    3344This 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.
