( Not yet tested on Raspbian Jessie!!! )
As of August 2015, it appears there's a new Kernel, 4.1.6, for Raspbian which takes care of all the dependencies for the DFRobot display. This means you should just be able to drop in a compiled
rp_usbdisplay.ko module and have it up and running in seconds. I'll be compiling up modules for the B+ and Pi 2, testing them, and piecing together a script to get them installed easily this week.
Hopefully it'll work- if you're looking to get a new USB display up and running watch this space.
Beta installer: https://github.com/pimoroni/rp_usbdisplay
This is a little advanced, but as long as you don't overwrite anything in /boot you can always recover your Pi by modifying the config file from another computer.
This guide is for the RFROBOT 2.8 USB Display on Pi 2 Raspbian only, don't follow it on any other setup.
Robopeak RPUSBDisplay kernel setup
You'll need to be competent with using the Raspberry Pi command-line to follow this guide.
- Step 1, make yourself a folder to work in:
- Step 2, fetch and "install" the kernel image:
sudo cp kernel7-rpusb.img /boot/
- Step 3, fetch and install the modules:
tar -zxf modules.tar.gz
sudo mv 3.19.2-v7+/ /lib/modules
- Step 4, tell your Pi 2 to boot with the new kernel:
Add the line:
- Step 5, make sure the rp_usbdisplay module loads at startup:
sudo nano /etc/modules
Add the line:
- Step 6. *Reboot and test!!
At this point, you should see the startup logo on your display, and then a brief period of static followed by the display going black
To verify that the display is working, throw some random data at it:
cat /dev/urandom > /dev/fb1
You'll see a message to the tune of
no space left on device and the display will show rainbow static. Random pixels!
My next post will include various different desktop configurations!
