How to Avoid Writing Device Drivers for Embedded Linux - Chris Simmonds, 2net

Feedback form is now closed.
Writing device drivers is time consuming and error prone. The good news is that in most cases you don't have to because Linux provides ready-made drivers for common types of interface. If you want to twiddle some GPIO pins, fade the brightness of an LED or read the temperature using a chip you got from Adafruit, it is all done for you. Well … almost all: you still have to write some user-space code to call the generic driver.

In this presentation I will give examples using three subsystems: GPIO, PWM and I2C. For each one I will show you how to write code to control hardware from the safe and simple environment of your application, written in C or C++ (bindings for other languages exist). If all goes well, there will be live demos of each category.
