Hello World example for Gamebuino-classic

Example command line build environment for Gamebuino-classic projects without needing the Arduino IDE when using Linux or MacOS.

How to build

Source checkout

This git repo uses submodules, so to clone a copy use...

git clone --recurse-submodules https://github.com/AnotherJohnH/HelloGamebuino.git

Build Dependencies

  • gcc-avr
  • libc-avr
  • cmake (at least v3.11.4)

Build configuration

  1. The gcc-avr and libc-avr dependencies can be satisfied by an install of the Arduino IDE. If this approach is taken then the ARDUINO_ROOT path needs to be set in Makefile so that $(ARDUINO_ROOT)/tools/avr/bin can be added to $PATH.

  2. The Makefile should also be edited to contain the expected path for the SD card when mounted.

Build commands

To build HELLO.HEX from hello.cpp...

make

To clean away the build directory...

make clean

To copy HELLO.HEX to an SD card...

make send

Customizing for a new project

  • In Makefile change <NAME> in the line EXECUTABLE = <NAME>
  • In CMakeLists.txt change <NAME> and <source> in the line add_executable(<NAME> <source> ${GB_SRC})

NOTE: In an attempt to make C/C++ easier to use the Arduino IDE supports .ino files. These are similar to normal C/C++ files but are pre-processed to auto-generate the declarations that would normally be necessary when splitting a project across multiple source files. .ino files are not supported by this build framework so .cpp, .c and .h files must be used and will be treated in the normal way.
