Hi Erel,
this insert don`t works. I have change to inline C, that works.
But in the meantime i think it is another problem.
The last year i have only worked with ESP32Dev-Moduls
A simple commandline like
x = NumberFormat(Temp,2,1)
gives a similar error
everytime when i have a arduino board selected (Due , uno ..).
A ESP32 board gives me no compiler Errror
F:\B4R\Projekte\KäseLager\Objects\bin\sketch\B4RCore.cpp.o: In function `B4R::B4RString:
rintableToString(Printable*)':
F:\B4R\Projekte\KäseLager\Objects\bin\sketch/B4RCore.cpp:358:
undefined reference to `operator new(unsigned int, void*)'
Have you a idea what is wrong in the IDE ??
