ESP32 Forum

I have some code in C++. I was running it on MBED board.

I want to try the same program on Will ESP32-WROVER. Does it provide support for this?

C++ program take data from CSV file, process the numerical content and predict some result.

The g++ compiler included with the ESP IDF toolchain works just fine, I've been using it for a while now. It's not the C++ part you should worry about, it's the other stuff you need to pay attention to - OS and peripheral libraries, build systems, etc. The simplicity of porting depends largely on how well your existing program is designed to be portable.
