In this chapter, we explored several different types of real-time scheduling techniques that can be used with a MicroPython project. We found that there are many different techniques that a MicroPython developer can leverage to schedule activities in their application. We found that each of these techniques has its place and varies based on the level of complexity a developer wants to include in their scheduler. For example, MicroPython threads can be used, but they are not fully supported in every MicroPython port and should be considered an in-development feature.

After looking at several techniques, we saw that the asyncio library may be the best choice for developers looking to get started with MicroPython. Python developers are already familiar with it and asyncio provides developers with cooperative scheduling capabilities that can provide them with the ability to handle asynchronous events in an efficient, non-blocking manner. This allows developers to get more out of their applications while wasting fewer cycles.

In the next chapter, we will explore how we can write drivers for a simple application that uses a push button to control the state of its RGB LEDs.
