板子是原子的Mini STM32.程序基本上都是原子送的例程，自己读懂以后基本上都是抄写了一遍，只不过程序只对应我板子上的芯片型号（先下载了例程，串口输出的芯片ID是4531），所以只保留了该芯片的初始化程序，并直接使用竖屏和快速IO模式。
现在的情况是，屏幕能够正常显示，各个功能函数能够正常使用，就是那个读取ID返回的值一直是FFFF。非常不解，请大家帮忙纠正下！谢谢~~~
 delay_ms(50); // delay 50 ms
 LCD_WriteReg(0x0000,0x0001); //打开TFTLCD模块的振荡器
 delay_ms(50); // delay 50 ms
 DeviceCode = LCD_ReadReg(0x00);  //读取TFTLCD驱动芯片的型号 
 printf(" LCD ID:%x ",DeviceCode); //打印LCD ID
//上面的读取ID的函数没有修改啊，为何返回值就不对了呢，但是使用原子的程序又没有什么问题！

//驱动芯片初始化 芯片型号4531，直接拷贝，没有修改的
