    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.

    Connect to Raspberry Pi

    1. prepare a common USB 2.0 cable with microUSB port(make sure it has data cable)

    2. compile fbusb for raspberry pi

    3. call 'sudo insmod fbusb.ko', if success, you can find fbusb log in dmesg.

    note: fbusb will map screen to /dev/fb1.

    Try framebuffer

    fbusb use 16bit color as default.

    1. set screen to black: dd if=/dev/zero of=/dev/fb0 bs=1000 count=768

    2. set screen to random pixel: dd if=/dev/urandom of=/dev/fb0 bs=1000 count=768

    note: on vocore, it is /dev/fb0; on raspi, it is /dev/fb1.

    User mode(use libusb instead of fbusb driver)

    this mode is for windows and other system can not use fbusb driver but we can use libusb.

    please check SDK README.md and source code send_frame.c/send_cmd.c/read_touch.c for usage.
