Using Arduino with Ada

Software Serial for Adafruit Trinket (TX only)

Trinket on breadboard

Some AVR devices, like attiny85 (on Adafruit Trinket, for example), do not have hardware UART. However, it would be still nice to have serial output from them.

I wrote a simple Soft_Serial package, which can use any GPIO pin as TX UART pin.

package Soft_Serial is
   Serial_Pin : Boolean renames AVR ...

AVR-Ada package for Debian Wheezy (7.x) on Raspberry Pi 1

As earlier for Ubuntu, I used the same quick-and-dirty package creation method and created AVR-Ada package for Raspberry Pi 1 running Debian Wheezy.

You can get the package from rpi1.ada-language.com by adding line:

deb http://rpi1.ada-language.com/wheezy ./

to your /etc/apt/sources.list file and running ...


Disqus comments disabled, and other changes

I have made few changes to the theme of the blog.

The biggest change is that I disabled the comments. There haven't been that many comments in general and in most cases it just adds some extra weight to the site.

If you wish to see the old comments ...


AVR-Ada and PN532, part 2: Mifare Classic, Yubikey NEO, I2C support

I continued tweaking my PN532 code and during the past few months I have added support for I2C interface, Mifare Classic tags (read-only), and Yubikey NEO keys (NFC Forum Type 4 interface).

PN532 and Arduino

I2C support means that you can use Adafruit PN532 Arduino Shield and normal Arduino UNO to run my ...


Read, write, and emulate NFC tags using Adafruit PN532 breakout board, Olimexino-328, and AVR-Ada

Recently, I have been playing with PN532 breakout board from Adafruit to read NFC tags and to communicate with NFC-enabled devices, like smart phones.

Adafruit's PN532 breakout board uses 3.3V voltage level and it is little tricky to use it with normal Arduino. So I ended up using ...
