f28027 内置温度传感器操作

麻烦各路大神帮我看下操作有什么问题，一直跳到非法操作中断那里去

void main(void)

{

//  long sum=0;

//  float vol=0;

    int16 sensorSample,DegreesC;

//  int i=0;



// Step 1. Initialize System Control:

// PLL, WatchDog, enable Peripheral Clocks

// This example function is found in the DSP2802x_SysCtrl.c file.

   InitSysCtrl();



// Step 2. Initalize GPIO:

// This example function is found in the DSP2802x_Gpio.c file and

// illustrates how to set the GPIO to it's default state.

   InitGpio();



// Step 3. Clear all interrupts and initialize PIE vector table:

// Disable CPU interrupts

   DINT;



// Initialize PIE control registers to their default state.

// The default state is all PIE interrupts disabled and flags

// are cleared.

// This function is found in the DSP2802x_PieCtrl.c file.

   InitPieCtrl();



// Disable CPU interrupts and clear all CPU interrupt flags:

   IER = 0x0000;

   IFR = 0x0000;



// Initialize the PIE vector table with pointers to the shell Interrupt

// Service Routines (ISR).

// This will populate the entire table, even if the interrupt

// is not used in this example.  This is useful for debug purposes.

// The shell ISR routines are found in DSP2802x_DefaultIsr.c.

// This function is found in DSP2802x_PieVect.c.

   InitPieVectTable();





// Step 4. Initialize all the Device Peripherals:

// This function is found in DSP2802x_InitPeripherals.c

// InitPeripherals(); // Not required for this example



// Step 5. User specific code:



   InitAdc();

   AdcOffsetSelfCal();



   InitLCD12864();
