Is it possible to create an xQueueHandle and send it into multiple tasks?

Thanks ESP_Sprite. I'd put the project away and was only recently able to return. I was able to do this with help from your comments. I ended up going to the CMakeLists.txt file and added the file names as below: set(COMPONENT_SRCS "example1.cpp" "example2.cpp" "main.cpp") set(COMPONENT_ADD_INCLUDED...

One thing to check is if exampleClass.cpp is actually compiled and linked in.

I'm not quite sure what you mean. Isn't the compilation and linking performed during the idf.py build/flash process? I'm not aware of any manual process that needs to be performed when creating a class.

I'm having trouble referencing class methods from the related .cpp file and hoping for some idea as to why it's failing. I've created an exampleClass with a .h file that includes: extern "C" { void app_main(void); } class exampleClass { public: void print(); private: }; and I've created the associat...

Thanks PeterR and chegewara. Your suggestions led me to the gcvt function: https://www.geeksforgeeks.org/gcvt-conv ... -string-c/

Does anyone have any luck in converting integers or doubles to strings in ESP32/esp-idf? Ideally, I'd like the function to work over an array of integers or doubles. I've tried using std::to_string(0) as a proof of concept but I get a compilation error: 'to_string' is not a member of 'std' std::to_s...

C doesn't (natively) support classes, you probably want C++. How can I switch it to C++? rename your .c file to .cpp put : extern "C" { void app_main(void); } in your .cpp file near the top change cmakelists.txt to point at your new .cpp file instead of the old .c file set(COMPONENT_SRCS "./main.cp...

Is it possible to use classes when developing for the esp32? I can't seem to get the syntax correct when building the .h and .c files.

Thanks for the reply markkuk. I had much better luck today with the strncat() and strcpy() functions. I did run into another problem that I'm hoping you can help me with. I am trying to send bytes over TCP using the socket send() function. I've noticed a problem when trying to send a byte with a val...
