Hier ein Beispiel wie man C-Code in die C++ Welt einbindet (aus dem Demo Programm):
/**********************************************************************\
* IO Extension Demo Program
* main.cpp
* v 1.1.0
\**********************************************************************/
extern "C"
{
#include "RP6M256.h"
#include "RP6M256Lib.h"
#include "RP6M256uart.h"
#include "RP6I2CmasterTWI.h"
#include "Yourcode.h" <- include your C-code modules inside 'extern "C"'!
}
#include "ioExt.h" <- include your C++-code modules outside of 'extern "C"'!
. . . . // nicht aller Code ist hier vom Source Code abgebildet – nur die wichtigen Stellen
int main() __attribute__((noreturn));
int main()
{
initRP6M256(); <- function calls of C-code modules
I2CTWI_initMaster(400);
initLCD();
clearLCD();
// init RP6 Io Extension
ioExt::Initialize(); <- function calls of C++-code modules (with namespaces)
// set RTC test date and time in local structure
ioExt::rtc.setDay(07);
ioExt::rtc.setMonth(03);
ioExt::rtc.setYear(2013);
ioExt::rtc.setHour(23);
ioExt::rtc.setMinute(59);
ioExt::rtc.setSecond(55);
