Hello, i am comming from the c world, i think i have to read some theory parts to work with this things ;-)
Oh, then it is a quite big change. Fundamentally, it is not possible to cast a C++ function to a C style function. The closest workaround that I've found is creating a C function wrapper to call my C++ function:
void mFunc_information(uint8_t param) { lcdml_utils.information(param); }
LCDML_add(0, LCDML_0, 1, "Information", mFunc_information);
mFunc_information
is passed to LCDML_add
and lcdml_utils
is an instance of the LcdmlUtils
class that I wrote.
The reason I'm asking is because the TaskScheduler library also has a object oriented (C++) interface.
Has the possibility been investigated to add support for C++ style callbacks? std::bind from?
This would allow the callbacks to be realized as member classes, thereby being able to use member variables with references to the LCDMenuLib2 and U8G2.
