本套程序使用 IAR for arm v6.3 所编译。使用 IAR 编译效率快，在 IAR 中一定要注意各种变量的定义，注意 unsigned char 与 unsigned short int 的使用界限，如果超过了 255，就不要用 unsigned char 了，尤其是在图像采集存到数组中时。正交解码功能用 s16 型变量，即 typedef short int s16;直接读取即可，就能测出正反转(This set of programs is compiled using IAR for arm V6.3. It is efficient to compile using IAR. In IAR, we must pay attention to the definition of various variables. We should pay attention to the use limit of unsigned char and unsigned short int. If more than 255, do not use unsigned char, especially when image collection is stored in an array. The function of orthogonal decoding is S16 type variable, that is, typedef short int S16; direct reading can be used to detect positive and reverse.)
