Improve IrDA to UART adapter


Final integration of the IrDA device with the Peggy2 board

While coming back to work on the Peggy2 board and it’s interaction with my PSP, I needed to fix some issues with the IrDA to UART adapter (this is the piece that allows the PSP to communicate to Peggy2 through infrared).

Basically I had to create a new support for the IrDA transceiver and also to test if the bi-directional communication works (it does, like a charm…! ).

IrDA Enabling a PC or Microcontroller


This all started as a spin-off project for the Twitter to PSP project.

The final setup, in which the PSP is talking to an Arduino through the IR link (using IrDA protocol)

Twitter – PSP (java) – Arduino (Peggy2)

… so it all started, after I managed to make my Peggy2 LED board work, and I was wondering what to do with it…?

What else more obvious than display Twitter messages on it?

Now here’s the high level “design”:

– Peggy2 board with an Arduino microcontroller on it, should receive data serially, either over wire or IR

– how to get the data from the internet ? I don’t want to use a ethernet shield or wireless one, and it turns out I’ve been for so long annoyed that I have a PSP lying around and not being used… So let’s use it, it has wireless and can be programmed in Java (J2ME) be using the PSPKVM (greaaaat job guys !)

So there are 2 problems:

1) program the PSP to connect to the internet and download tweets from there

2) communicate between the PSP and the Arduino on Peggy

1) PSP to twitter.com
