Part Number: TM4C123GH6PM
Tool/software: TI-RTOS
I am working on TIRTOS platform using TM4c123GH6PM.. I want to create LED Toggling using C++ using concept of Classes and Objects . Below is my code where I have used one idle function and tried to toggle LED. My code is on .cpp extension. Empty.c file I have excluded from build because it was not supporting classes and object..
#include <xdc/std.h> //mandatory - have to include first, for BIOS types
#include <ti/sysbios/BIOS.h> //mandatory - if you call APIs like BIOS_start()
#include <xdc/runtime/Log.h> //needed for any Log_info() call
#include <xdc/cfg/global.h>//header file for statically defined objects/handles
#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_types.h"
#include "inc/hw_memmap.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
#include "inc/hw_ints.h"
#include "driverlib/interrupt.h"
#include "driverlib/timer.h"
#include <time.h>
void hardware_init(void);
void ledToggle1(void);
void main(void)
{
hardware_init(); // init hardware via Xware
BIOS_start(); // Start BIOS Scheduler (never returns)
class LED_Status
{
public:
int ON;
int OFF;
};
LED_Status status;
status.ON=8;
status.OFF=0;
}
void hardware_init(void)
{
//Set CPU Clock to 40MHz. 400MHz PLL/2 = 200 DIV 5 = 40MHz
SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_XTAL_16MHZ|SYSCTL_OSC_MAIN);
// ADD Tiva-C GPIO setup - enables port, sets pins 1-3 (RGB) pins for output
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3);
}
void ledToggle1(void)
{
GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_3, status.ON); // LED ON
SysCtlDelay(2000000); // DELAY
GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_3, status.OFF); // LED OFF
SysCtlDelay(2000000);
}
I am getting the following errors when I compile .cpp file.

How could this problem be solved. I have to use C++ concepts like Classes and Objects.
This code runs fine on NON RTOS .cpp files but its not working here
