Linux Device Drivers Development

Summary

Having reached the end of this chapter, you should now be familiar with the IIO framework and vocabulary. You should also know what channels, devices, and triggers are. You can even play with your IIO device from the user space, through sysfs, or a character device. The time to write your own IIO driver has come. There are a lot of existing drivers available that do not support trigger buffers. You can try to add such features to one of them. In the next chapter, we will play with the most useful/widely used resource on a system: the memory. Be strong, the game has just started.
