背景：DSP芯片为TMS320F2812，实现的是两路数据实时采集并且经过MAX7219在八位数码管（每四位数码管对应一路数据采集的值）显示。

我已经成功编写了ADC采集的程序。
#include "DSP281x_Device.h" // DSP281x Headerfile Include File
#include "DSP281x_Examples.h" // DSP281x Examples Include File
// Prototype statements for functions found within this file.
interrupt void adc_isr(void);
// Global variables used in this example:
Uint16 LoopCount;
Uint16 ConversionCount;
Uint16 Voltage1[1024];
Uint16 Voltage2[1024];
main()
{
InitSysCtrl();//初始化cpu
DINT;//关中断
InitPieCtrl();//初始化pie寄存器
IER = 0x0000;//禁止所有的中断
IFR = 0x0000;
InitPieVectTable();//初始化pie中断向量表
// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.
EALLOW; // This is needed to write to EALLOW protected register
PieVectTable.ADCINT = &adc_isr;
EDIS; // This is needed to disable write to EALLOW protected registers
AdcRegs.ADCTRL1.bit.RESET = 1;// Reset the ADC module
asm(" RPT #10 || NOP");// Must wait 12-cycles (worst-case) for ADC reset to take effect
AdcRegs.ADCTRL3.all = 0x00C8;// first power-up ref and bandgap circuits
AdcRegs.ADCTRL3.bit.ADCBGRFDN = 0x3;// Power up bandgap/reference circuitry
AdcRegs.ADCTRL3.bit.ADCPWDN = 1;// Power up rest of ADC
// Enable ADCINT in PIE
PieCtrlRegs.PIEIER1.bit.INTx6 = 1;
IER |= M_INT1; // Enable CPU Interrupt 1
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM
LoopCount = 0;
ConversionCount = 0;
// Configure ADC
AdcRegs.ADCMAXCONV.all = 0x0001; // Setup 2 conv's on SEQ1
AdcRegs.ADCCHSELSEQ1.bit.CONV00 = 0x0; // Setup ADCINA3 as 1st SEQ1 conv.
AdcRegs.ADCCHSELSEQ1.bit.CONV01 = 0x1; // Setup ADCINA2 as 2nd SEQ1 conv.
AdcRegs.ADCTRL2.bit.EVA_SOC_SEQ1 = 1; // Enable EVASOC to start SEQ1
AdcRegs.ADCTRL2.bit.INT_ENA_SEQ1 = 1; // Enable SEQ1 interrupt (every EOS)
// Configure EVA
// Assumes EVA Clock is already enabled in InitSysCtrl();
EvaRegs.T1CMPR = 0x0080; // Setup T1 compare value
EvaRegs.T1PR = 0x10; // Setup period register
EvaRegs.GPTCONA.bit.T1TOADC = 1; // Enable EVASOC in EVA
EvaRegs.T1CON.all = 0x1042; // Enable timer 1 compare (upcount mode)
// Wait for ADC interrupt
while(1)
{
LoopCount++;
}
}
interrupt void adc_isr(void)
{
Voltage1[ConversionCount] = AdcRegs.ADCRESULT0 >>4;
Voltage2[ConversionCount] = AdcRegs.ADCRESULT1 >>4;
// If 40 conversions have been logged, start over
if(ConversionCount == 1023)
{
ConversionCount = 0;
}
else ConversionCount++;
// Reinitialize for next ADC sequence
AdcRegs.ADCTRL2.bit.RST_SEQ1 = 1; // Reset SEQ1
AdcRegs.ADCST.bit.INT_SEQ1_CLR = 1; // Clear INT SEQ1 bit
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; // Acknowledge interrupt to PIE
return;
}

而且经文献查的利用MAX7219的显示程序有：
//初始化MAX7219
void InitDisplay(void)
{
WriteWord(0x0b,0x07);//设置扫描界限
WriteWord(0x09,0xff);//设置译码模式
WriteWord(0x0a,0x0a);//设置亮度级别
WriteWord(0x0c,0x01);//设置为正常工作模式
}
//向MAX7219写入字（16位）
void WriteWord(uchar addr,uchar num)
{
uchar entire;
entire=(addr<<8)+num;
GpioAataRegs.GPDDAT.bit.GPIOD0;//将LOAD信号置为低电平，准备移入数据
delay(200);
GpioDataRegs.GPDDAT.bit.GPIOD0=1;//将LOAD信号置为高电平，锁存进相应寄存器
}

然而问题来了，不管我怎么把显示程序加入主程序中，都无法调试成功，请有知晓的大神告知！拜托了，最近愁的都吃不下饭。

楼主，你的硬件电路是什么样的。
