Recently, I wanted to access I2C EEPROM with Arduino. However, AVR-Ada (1.1.0) provides no support for I2C interface which many AVR processors and Arduinos have. So, I had to write a package ("Two_Wire") for it.

Example code is available at arduino-eeprom repository and below is the used circuit ...

To test AVR-Ada with small attiny13 processors, I made a little "development board" for me:

It can run hello example out of the box and blink the green led. The red led indicates power.

I recently got write access to the AVR-Ada repository and now I have pushed my changes there.

These changes improve support for Atmega2560, Attiny13a, and Attiny2313 processors. Attiny13a and Attiny2313 are pretty uninteresting, although common, AVR processors. I happen to use them in my projects because they are cheap and ...

I finally got my code working with Arduino Ethernet Shield and put it available at http://bitbucket.org/tkoskine/arduino-ethernet/.

Only receiving data via TCP client connections is supported, but I plan to improve the library as my time permits.

I updated my AVR-Ada port to version 1.1.0. It consists of three parts:

• AVR-GCC 4.3.2 with Ada support - http://bitbucket.org/tkoskine/avr-gcc
• AVR-Ada 1.1.0 runtime files - http://bitbucket.org/tkoskine/avr-ada-rts
• AVR-Ada 1.1.0 library files (AVR.* packages) - http://bitbucket.org/tkoskine ...
