最近做了一个小项目，里面一个小部分，基于STM32刷卡带触摸屏，功能可能有点简单，但是可以继续往下编。还有刷卡号的识别要更改。
使用触摸屏-SPI程序时如果出现触摸不灵或者误差大，可以按照下面方法进行校正修改，如果使用可以强制校准程序则不需要，只需通过K_UP按键强制校准即可。
如果下载程序后对触摸屏划线，没有出现线条，可以显示触摸值变化，这个是因为没有对触摸屏校正，因此只需要在 touch.c 这个文件内的函数 void TOUCH_Init(void)，将这个函数内的语句
if(TouchAdj.posState != TOUCH_ADJ_OK)
{
TOUCH_Adjust(); //校正
}
改成
if(TouchAdj.posState == TOUCH_ADJ_OK)
{
TOUCH_Adjust(); //校正
}
编译后将HEX下载到开发板内进行触摸屏校正，校正完成后再修改为!=就可以了。
