Raspberry Pi Serial Comms: Gambas + wiringPi

I've been playing around with serial comms on my Pi/Picaxe dev rig.

Using Gordon's wiringPi library makes it easy to open the gpio serial comms port on the Pi and write code with Gambas.

So this post involves writing a simple Picaxe program, and then using wiringPi and Gambas on the Pi to communicate with the Picaxe.

RaspberryPi, Serial Comms & PHP

I've been playing around with serial comms on 2 Raspberry Pi computers for the last couple of days.

And I now understand a little of the black-art required to get this working, including how to send serial data via a PHP web page.

So I thought I'd write up the details before I have time to forget it all again!
