One of the nice achievements of the IDF is the menu-driven configuration. What I find even nicer is that custom configuration points can be created. These are then automatically integrated into the main menu. First off: the library „esp_system.h“ is needed in the source code, otherwise it won't work. After changes to the menu, run an idf.py clean. To create such a configuration point, take...

A popular example in the Arduino environment is Blink. This switches an LED on and off with a short pause. We will come to GPIO actions in the next chapter; we will deal with blinking here. In the Arduino environment too, it is always advised to avoid code interruptions with delay. There are some constructs there with...

When developing on the microcontroller, it's often important to have the occasional output to gauge whether the developed code is doing the right thing. It's a shame when such outputs still burden the finished product. So that the debugging code makes it into the final product, or only to a limited extent, there are in nearly…

Error handling in the IDF is one of the core functionalities. You'll encounter it in practically every example program, which is why I'd like to go into more detail here. All important IDF functions return error codes. These can either be handled manually (if condition + own handling) or they can be passed to a special macro (function) for...

Direct output to the console is achieved in the IDF with printf. However, one should be sparing with this, as there are other mechanisms for debugging purposes or error handling, for instance. These can then also be switched on and off via Menuconfig and thus do not burden the CODE. The test code for a simple output looks like this…
