Summary

Having reached the end of this chapter, you are now armed to deal with any PWM controller, whether it is memory mapped or externally sitting on a bus. The API described in this chapter will be sufficient to write and enhance controller driver as a consumer device driver. If you are not comfortable with the PWM kernel side yet, you can use the user space sysfs interface fully. In the next chapter, we will discuss regulators, which are sometimes driven by PWM. So, please hold on; we are almost done.

GNU/Linux Rapid Embedded Programming

GNU/Linux Rapid Embedded Programming

Embedded computers have become very complex in the last few years and developers need to easily manage them by focusing on how to solve a problem without wasting time in finding supported peripherals or learning how to manage them. The main challenge with experienced embedded programmers and engineers is really how long it takes to turn an idea into reality, and we show you exactly how to do it. This book shows how to interact with external environments through specific peripherals used in the industry. We will use the latest Linux kernel release 4.4.x and Debian/Ubuntu distributions (with embedded distributions like OpenWrt and Yocto).
