[HARP] Working on the LED drivers

Today and yesterday we’ve kept working on the GPIO and SPI buses. They seem to work just fine but we still have some troubles with the LED matrix. To fix the problem we made a lot of hardware tests using logical analyzers. It’s getting better though (after some bug fixes) and tomorrow we’re hopping to get everything running in order to display an image. Cf. Alexandre’s post to see the whole system running with some LED turned on.

Also I started looking at documentation concerning how to create a kernel module. We might need to use our program as one to avoid latencies while running it.
