Yet another AVR Abstraction Library

Or yet another AVR Library

We are in experimental state.

Associated projects:

  • yaamake - Independent makefile system to ease project building and programming.

About

Trying to make avr coding super easy. Result should be able to replace arduino library in usability.

#include <yaal/io.hh>

PortB3 led;

void main() {
  led.output();
  
  for (;;) {
    led.on();
    delay_ms(1000);
    led.off();
    delay_ms(1000);
  }
}

Those are mainly for directions, but for working examples look into examples directory.

Why YAAL?

Why should I use YAAL instead of Arduino. Arduino is so easy to use!

Well. Because of the performance. Read more in why_yaal.md

Howto start project using yaal?

Run commands from following (change paths and commands to match your liking).

mkdir my_project_path
cd my_project_path
git init .
git submodule add https://github.com/raphendyr/yaal.git vendor/yaal
## if you do not want to have yaamake installed (read yaamake's README.md)
#git submodule add https://github.com/raphendyr/yaamake.git vendor/yaamake
#(cd vendor/yaamake && make NO_TEENSY=1)
#./vendor/yaamake/yaamake --init-project --make-initial --yaal=vendor/yaal
yaamake --init-project --make-initial --yaal=vendor/yaal
git commit --amend -m "Project initialization"

Last line is optional as yaamake creates you the initial commit. You should edit the message (the last line) to be more suitable to you.

Then start by editing Makefile to match your hardware and write test code into main.cpp. After that run make to build it and make program to flash your chip.

If you are using teensy, remove parameter NO_TEENSY=1 from above (building teensy_loader_cli requires libusb-dev or similar package).
