标题: 程序的数据采集问题
void ImageCapture(unsigned char *ImageData) {

unsigned char i;
unsigned int  temp_int;

TSL1401_SI = 1;       /* SI  = 1 */
SamplingDelay();
TSL1401_CLK = 1;       /* CLK = 1 */
SamplingDelay();
TSL1401_SI = 0;       /* SI  = 0 */
SamplingDelay();

//Delay 20us for sample the first pixel
for(i = 0; i < 20; i++) {
      Cpu_Delay1us();
//}

//Sampling Pixel 1
temp_int = ADCvalue(0);
*ImageData=temp_int; 编译时  这一行一直警告  可能会对是数据烧近最小系统是确实丢失了数据请问大神门  怎么改？谢谢
TSL1401_CLK = 0;       /* CLK = 0 */

for(i=0; i<127; i++) {
      SamplingDelay();
      SamplingDelay();
      TSL1401_CLK = 1; /* CLK = 1 */
      SamplingDelay();
      SamplingDelay();
      //Sampling Pixel 2~128
      temp_int=ADCvalue(0);
      *ImageData++=temp_int;
      TSL1401_CLK = 0; /* CLK = 0 */
}
SamplingDelay();
//SamplingDelay();
TSL1401_CLK = 1;       /* CLK = 1 */
SamplingDelay();
//SamplingDelay();
TSL1401_CLK = 0;       /* CLK = 0 */
}
}
