This workshop offers an insight into the programming of drivers under Linux. We will work our way from a Hello World kernel module to our own small driver for controlling a 7-segment display on a Raspberry Pi.
The workshop is interactive and the knowledge learnt can be applied immediately. All you need is a laptop. The Raspberry Pis and other hardware will be provided.
Topics
The following topics will be covered in the workshop:
- What does the kernel do?
- Hello World Kernel Module
- Makefile for building a Linux driver
- Using GPIOs in a driver
- How to communicate with a driver via a character device file
If we still have time afterwards, we can also look at other topics, e.g. interrupt handling, timers or the device tree.
Required software for GNU/Linux: text editor, ssh and sshfs. For third-party operating systems, please look for suitable alternatives yourself.
Required hardware: Laptop with USB A and Ethernet port (to connect the Raspberry Pi) or USB A and Ethernet dongle.
