Yep, that's likely what is going to be my "solution". To follow the demo and see if I can make it run on the Arduino nano ESP32. This board has an ESP32 S3 board inside it, so it should not be a problem.
Where do you see another 5 libraries? If you are talking about the demo example the only libraries that are not from the ESP packages is ESP32-Helpers which comes with the Demo code.
github. I just went back and looked at your OP and see the MAXON folks have really NOT organized their code like most do. Having a second github for the demos instead of inside the library is not convenient. Of course the big issue is only providing a Vscode PlatformIO compatible library.
NOTE: They are NOT open source, the library is a .a file type.
There is, Sorry, I don't have the details in front of me but just change what I call NAME to the correct name.
Just create a folder in your libraries folder in your sketchbook folder and name it NAME then place the NAME.hpp file in a src folder in that folder and the .a file as well. If you need help, send me a link to the example code and I will try to set it up here.
It does seem to read the EPOS4Class.hpp file properly but it doesn't seem to read the libEPOS4Class.a file as it returns the following compilation error when testing this single line of code:
EPOS4 motor(1); /**< Construct the EPOS4 object. */

collect2.exe: error: ld returned 1 exit status
I've also tried creating a folder inside the sketch folder "Test_EPOS4" but it simply didn't find the "EPOS4Class.hpp" file.
However, I'm not even trying to execute all the sample code as it is a bit complex, I'm just trying to create an EPOS4 object as they do at the beginning of the code of the demo with:
//#include "freertos/FreeRTOS.h"
//#include "freertos/task.h"
//#include <stdio.h>
//#include <string>
//#include <vector>
//#include "esp_err.h"
//#include "esp_log.h"
#include "EPOS4Class.hpp"
/**
* The Node-ID of the EPOS4 to be controlled.
* Can be configured using EPOS Studio or DIP switches. Refer to EPOS4 Hardware Reference.
**/
const int motorNodeID = 1;
EPOS4 motor(motorNodeID); /**< Construct the EPOS4 object. */
void setup() {
Serial.begin(9600);
}
void loop() {
delay(200);
}
Also, I'm thinking that it might be a problem with the "library.json" file maybe?
The .a file has to be in your library folder. I will show you another library that I know works and has a .a file.
I don't know why the 8266 folder is there, you may be able to eliminate that.
Set up your libraries folder as in the pic. Delete the json, perhaps rename the .a file to be as you show libEPOS4Class.a. I am guessing. I will not be testing further.
Here is contents of the library.properties file
The current state of the folders is:
\Documents\Arduino\libraries\EPOS4Class\src\esp32s3 is where the .a file is.
\Documents\Arduino\libraries\EPOS4Class\src\ contains the EPOS4Class.hpp file.
\Documents\Arduino\libraries\EPOS4Class is where the library.properties file is.
This file currently looks like this:
Maybe you could share how the library.properties of your library is written to see if it maybe a problem with the parameters.
Anyway. I does now use the precompiled binaries. However, it says that the .a file doesn't exist when it tries to compile, see:
Library - has been declared precompiled:
Using precompiled library in C:\Users\*****\*****\Arduino\libraries\EPOS4Class\src\esp32s3
xtensa-esp32s3-elf-g++: error: C:\Users\*****\AppData\Local\arduino\sketches\DDCDD7A2AC67D132D5770655BC1C7E5F\libraries\EPOS4Class\EPOS4Class.a: No such file or directory
exit status 1
Compilation error: exit status 1
Here is what I have. It compiles after I comment out some EPOS4 stuff I don't have the code for and at the end fails on line 26 where it tries to construct the EPOS4 object because I don't have that code (in the .a file)
As far as I can tell this is the folder org that is going to work.
It is required. The library must provide a precompiled binary for each of the supported targets. So a separate folder is used for each of the targets.
I strongly recommend that anyone working with the internals of precompiled Arduino libraries, or supporting those attempting to do so, should take the time to study the relevant section of the Arduino Library Specification:
