How It Works

The screen has memory to store the picture, so you can directly send data through USB, data format is R-G-B-R-G-...in SDK the API has packaged all necessary functions, please also check the demo of DOOM to study how it works.

Current version support framebuffer driver for VoCore2 and Raspberry, please download SDK and try fbusb.ko

Tutorials

Connect to VoCore2

1. prepare a common USB 2.0 cable with microUSB port, make sure the cable has data wires(some USB cables are only for power charge and do not have data wires, it does not work with this screen).

2. compile fbusb driver, its source code is in SDK, or get from github.com/vonger/vocore2, in package/utils/fbusb.

3. power off VoCore2 and connect the screen with USB cable to VoCore2's USB port.

4. connect VoCore2 to 5V power, then around 10~15 seconds, you can find the screen LED is light, after around 0.5s, screen will become white, then we know it works.

note: fbusb will map screen to /dev/fb0.
