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 …

My AWS-powered sites stronglytyped.org and Ahven's homepage ahven.stronglytyped.org now support IPv6 connections also.

This was possible after Linode started supporting native IPv6 in some of its datacenters.

Again, only Ada Web Server and iptables were used. There is no separate frontend http server written in another language …

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 finally managed to release Ahven 1.9 (download zip).

This is a small bug fix release only to allow Ahven compile with GNAT GPL 2010 also.
