到了20ms之后，进行采样，不过感觉采样之前已经将之前的清掉了，求大神指点

曝光开始点
void StartIntegration(void) {
unsigned char i;
TSL1401_SI = 1;       /* SI  = 1 */
SamplingDelay();
TSL1401_CLK = 1;       /* CLK = 1 */
SamplingDelay();
TSL1401_SI = 0;       /* SI  = 0 */
SamplingDelay();
TSL1401_CLK = 0;       /* CLK = 0 */
for(i=0; i<127; i++) {
      SamplingDelay();
      SamplingDelay();
      TSL1401_CLK = 1; /* CLK = 1 */
      SamplingDelay();
      SamplingDelay();
      TSL1401_CLK = 0; /* CLK = 0 */
}
SamplingDelay();
SamplingDelay();
TSL1401_CLK = 1;       /* CLK = 1 */
SamplingDelay();
SamplingDelay();
TSL1401_CLK = 0;       /* CLK = 0 */
}

到了20ms之后，进行采样，不过感觉采样之前已经将之前的清掉了，求大神指点

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 = AD_Measure12(0);
*ImageData++ = (byte)(temp_int>>4);
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 = AD_Measure12(0);
      *ImageData++ = (byte)(temp_int>>4);
      TSL1401_CLK = 0; /* CLK = 0 */
}
SamplingDelay();
SamplingDelay();
TSL1401_CLK = 1;       /* CLK = 1 */
SamplingDelay();
SamplingDelay();
TSL1401_CLK = 0;       /* CLK = 0 */
}

采样的数据实际上是上一个20ms内对应的曝光时间啊没有错啊

楼主  void StartIntegration(void) {
   unsigned char i;
   TSL1401_SI = 1;       /* SI  = 1 */
   SamplingDelay();
   TSL1401_CLK = 1;       /* CLK = 1 */
   SamplingDelay();
   TSL1401_SI = 0;       /* SI  = 0 */
   SamplingDelay();
   TSL1401_CLK = 0;       /* CLK = 0 */
   for(i=0; i<127; i++) {
      SamplingDelay();
      SamplingDelay();
      TSL1401_CLK = 1; /* CLK = 1 */
      SamplingDelay();
      SamplingDelay();
      TSL1401_CLK = 0; /* CLK = 0 */
   }
这段用来干啥的？？

启动ccd采集

没问题啊？
