learning linux drivers

Question

Hello all

I am learning now days programming drivers.

I am doing my learning from this book Linux Device Drivers

But I am little bit lack of practice. Can you recommend me some simple projects that I can get started with.

Or some open source project that newbie can understand what is going on.

Additional examples and tutorials will be welcomed .

Thanks for help.

Answer 1

Just for the record, there is a free onlive version of the LDD3 book.

Answer 2

Free software magazine has an article about that :

this tutorial is downloadable as PDF.

This article describes the programming of a USB driver for a home made multicolored light. I think its quite interesting :)

For more "complete" drivers, I would look at the code of "serial" drivers (meaning driver for devices connected to a plain old serial port or USB port) because the data transfer between your computer and the device feels more natural.
