Tero's blog

My Arduino blog contains two new blog entries:

• a blinking LED example, for those who are just starting with Ada and Arduino
• and IBM Thinkpad T42 BIOS password recovery for people who own Thinkpad, have some soldering skills, and are already familiar with Arduino and Ada.

Using 16x2 LCD display for text output purposes is sometimes more convenient than serial communication via UART/USB.

But if you do the wiring on the breadboard you get quite a mess:

So, I wanted to create a shield for Arduino to make the LCD usage easier.

AVR-Ada includes library …

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 …

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.
