7-segment-leds on the MAX7219 on the Banana Pi or Raspberry Pi (not tested).
Show arbitrary numbers and lettes on the 7-segment-display.
Clone the repository and run ./build.
This installs includes and library in /usr/local/include and /usr/local/lib. Binaries in the /usr/local/bin folder.
Go to the source directory and use the mighty force of shining CMake :D to compile the pico project.
The wiringPi sub folder contains the internal interface library for the installed wiringBP library.
Do make install to install the library in /usr/local.
(I used Armbian stretch but also more recent versions should work).
