Templates

To get started with C development, it’s easiest to clone the example or a template for the board and environment you’re using from GitLab.

Important

If there are build errors about the compiler not finding certain includes from libyggdrasil, make sure you cloned the template repository recusively with --recurse-submodules. Without this flag, the libyggdrasil folder will be empty.

Midgard

git clone https://gitlab.ti.bfh.ch/yggdrasil/midgard/midgard_template --recurse-submodules

Asgard

Coprocessor

git clone https://gitlab.ti.bfh.ch/yggdrasil/asgard/asgard_coprocessor_template --recurse-submodules

Linux

git clone https://gitlab.ti.bfh.ch/yggdrasil/asgard/asgard_linux_template --recurse-submodules

Examples

Examples are a nice way to demonstrate the power of Yggdrasil and to learn how to use different aspects of the support library.

Midgard

git clone https://gitlab.ti.bfh.ch/yggdrasil/midgard/midgard_examples --recurse-submodules

Following examples are available:

  • TotalGB Gameboy / Gameboy Color Emulator with Super Mario Land 2 loaded by default. Available ROMs are Tetris, Super Mario Land 2 and The Legend of Zelda: Link’s Awakening

  • Mandelbrot / Julia Set generator with Joystick support

  • Azure RTOS example

C interface in C++

In a .cpp file, libyggdrasil will automatically be put into C++ mode. It’s encouraged to use the C++ interface in this case since it’s a lot more readable and easier to use.

Note

If for any reason the C interface is preferred over the C++ one while still writing C++ code, it can be used by adding the following define before including the libyggdrasil header.

#define YGGDRASIL_USE_C_INTERFACE
