CM1 ADAPTORS

Attaching Raspberry Pi Official 7" Display to the Compute Module IO Board This document is a work in progress and is intended for advanced users. For the display to work with the Compute Module, the firmware needs to be from October 23rd 2015 or later (use vcgencmd version to check). For the display to work with the Compute Module 3, the firmware needs to be from October 2016 or later. Note: The Raspberry Pi Zero camera cable cannot be used as an alternative to the RPI-DISPLAY adaptor, because its wiring is different. Quickstart — display only 1. Connect the display to the DISP1 port on the Compute Module IO board through the 22W to 15W display adaptor. 2. Connect these pins together with jumper wires: GPIO0 - CD1_SDA GPIO1 - CD1_SCL 3. On the Compute Module, run: sudo wget https://goo.gl/iiVxuA -O /boot/dt-blob.bin 4. Reboot for the dt-blob.bin file to be read. Quickstart — display and camera(s) This will enable disp1 and cam1 , with the option of enabling cam0 . 1. Connect the display to the DISP1 port on the Compute Module IO board through the 22W to 15W display adaptor, called RPI-DISPLAY. 2. Connect the Camera Module to the CAM1 port on the Compute Module IO board through the 22W to 15W adaptor called RPI-CAMERA. Alternatively, the Raspberry Pi Zero camera cable can be used. 3. (Optional) Connect the Camera Module to the CAM0 port on the Compute Module IO board through the 22W to 15W adaptor called RPI-CAMERA. Alternatively, the Raspberry Pi Zero camera cable can be used. 4. Connect these pins together with jumper wires: GPIO0 GPIO1 GPIO4 GPIO5 - CD1_SDA CD1_SCL CAM1_IO1 CAM1_IO0 Please note that the wiring is slightly different from that on the Camera page, in that you are using GPIO pins 4 and 5 instead of 2 and 3. 5. For cam0 , add links: GPIO28 GPIO29 GPIO30 GPIO31 - CD0_SDA CD0_SCL CAM0_IO1 CAM0_IO0 (Please note this image needs to be updated to show two Camera Modules, or have the extra jumper leads removed) 6. On the Compute Module, for the display and one Camera Module, run: sudo wget https://goo.gl/gaqNrO -O /boot/dt-blob.bin For the display and two Camera Modules, run: sudo wget https://goo.gl/htHv7m -O /boot/dt-blob.bin 7. Reboot for the dt-blob.bin file to be read. (Please note this image needs to be updated to show two Camera Modules, or have the extra jumper leads removed) Software support There is no additional configuration required to enable the touchscreen. The touch interface should out work of the box once the screen is successfully detected.
