A few years ago I bought a couple of these boards for about £25.
They provide:
- 5 digital input channels
- 8 digital output channels
- 2 analogue inputs
- 2 analogue outputs (8 bit resolution)
So, I thought... how hard can it be... and actually it is quite easy. The source is on sourceforge and I'm packaging it so you can pull libvelleman from garage, plug in a board and PUSH :)
As you can see the test program implements K.I.T.T. for you...
So now all we need is someone with an N900 to help me test it...
(Warning: Don't get your hopes up - it appears that the N900 can't (yet?) act as a normal USB host; so no plugging in printers....)
