The main ultibo program calls the zig function named zigmain. zigmain logs the command line arguments that are passed to it. zigmain then registers a callback with the raspberry pi userland that is embedded in ultibo. This callback responds to tv remote controller button presses by recording a message in the ultibo log (displayed on screen.)

The tv requires cec (consumer electronics control.)

ultibo supports a lot of the raspberry pi hardware and accessories and has many software features including various free pascal packages .

Development

Dependencies:

• Developed on debian 9/x86_64
• Install ultibo using ultiboinstaller.sh
• Install zig and add it to the PATH (must use most recent master from https://ziglang.org/download)
• Install the arm embedded tool chain https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
  • The installation directory is /usr and if not using gcc-arm-none-eabi-8-2018-q4-major then the build.zig file must be modified to reflect the correct path

Obtain this repo:

git clone https://github.com/markfirmware/zig-on-rpi-using-ultibo
