How to use
How to use on BPI-M1
For the Banana Pi ,just Insert these two module like the picture Below
How to use on BPI-M3
OS: BPI-M3 Ubuntu15.10 (Kernel3.4)
Version: 1.0 HDMI
Step 1: Download WiringPI
$ git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi.git1 -b BPI_M3 $ cd BPI-WiringPi $ chmod +x ./build $ sudo ./build
Step 2 : Copy smaple code to Blue_RGB8*8.c file
$ sudo vi Blue_RGB8*8.c
Step 3 : Compile Blue_RGB8*8.c
$ gcc -o Blue_RGB8*8 Blue_RGB8*8.c -l wiringPi
Step 4: Run Blue_RGB8*8
$ sudo ./Blue_RGB8*8
