Summary

avr-framwork is a collection of functions and examples used for programming on the avr platform. For example: i2c implementation, simple uart abstraction with stdin/stdout redirection, simple I/O abstraction layer for communicating with ports and more. Also there are some examples that are always enhanced by new ones if new functionality swaps in.

Supported devices

atmega2560(F_CPU=16000000)

Building on linux with git, gcc/clang and autotools

Prerequisites

• avr-gcc
• avr-libc
• autotools

Clone avr-framework from github: git@github.com:ckruczek/avr-framework.git

$ git clone git@github.com:ckruczek/avr-framework.git
$ cd avr-framework
$ autoreconf --install
$ ./configure --host=avr --enable-m2560=yes
$ make

The fourth line enables the use of the atmega2560 architecture.

Building an example

To build an example change to the example directory. For example the blinky example.

$ cd samples/blinky

You now find a predefined Makefile that you can trigger as follow:

Build the example

$ make -B

Upload the example

$ make program

If your tty is different to dev/ttyACM0 you have to adapt the port accordingly. So change the AVRDUDE_PORT variable in the Makefile according to your port.
