Hi experts,
I am just starting with ESP32. Nothing serious, just for hobby projects.
I am looking for a list of programming commands with some minimum description/explanation for use in ESP32 sketches.

I know that sketch commands are part of header files e.g. <wifi.h> or <time.h> etc. included in the sketch
But how do I know which all <xxx.h> header files are available for ESP32 at all?
I assume that there would be some documentation available somewhere on Internet on this. Would be very greatful if someone could direct me to any "Link" or Website for this, please.

Thanks and best regards

 

There will not be a definite answer to your question as just about anything will be available if it is written. You can write your own and add to the "programming commands".
There are many add-on libraries that folk have published and this too can be confusing as many have the same name but operate in a different manner.
So, you will not be able to get a full list of commands.
Oh, and I am not an expert, just a user passing on my observations.

 

Good chance if you google your needs, a library exists. Far too many for any one site to list them.

 

For the record, what you want are function calls not commands. In the Arduino world, libraries are often for all or a list of architectures. This means that a list of all function calls that would apply to the ESP32 would be uselessly large.

The easiest way to get an idea of the important libraries is to look through the examples and play around modifying them. The list of examples for ESP that install with the community board support is a good starting point to get an idea of which libraries would be particularly applicable.

Good luck with your learning. You can always ask specific questions here, there is plenty of help to be found.

 

I would suggest you Google projects that do something similar to your intents, Study that code and see how you can adapt it to your exact needs.

For the most part I find these projects libraries poorly documented and you will need the sample examples and some reverse engineering to get things up and running.

 

A good place to start:
Welcome to ESP32 Arduino Core’s documentation — Arduino-ESP32 2.0.2 documentation (readthedocs-hosted.com)

Remember, ESP Arduino is a "clone" of Arduino, so commands should closely match the Arduino docs:

Arduino Reference - Arduino Reference

Also of interest:

ESP32 Arduino - ESP32 Forum

 

My favorite web site that I've mentioned times before is https://randomnerdtutorials.com/
They have a lot of good projects and info. Well wort a look!

 

Since you used the term Sketch I infer that you are using the Arduino API/GUI. So most of your programming will be in C/C++. You can Find libraries that are pre-made on the site for many things you may want to do. https://randomnerdtutorials.com/ is a great site for ESP32 stuff and offer great training info. GitHub is another great place for libraries and examples. Have fun

Hi everyone,
Thanks a lot for your comments and hints. They are very helpful.
I will try to work my way through those as applicable on project by project basis.
Thanks again and best regards
