  这是一个TFT液晶的初始化程序，小弟对液晶不太了解，想看看液晶的驱动过程，Driver_IC = Read_Reg(0x00)                   ;这句读出来 Driver_IC是液晶的型号？

我怎么通过 Driver_IC这个数值确定是哪一款液晶，或者说怎么 通过 Driver_IC的数值来查找  这块TFT的驱动资料，我想找到datasheet对这个过程的描述，自己写一下TFT的驱动

好像不同的TFT彩屏都有一个ID，用一个函数读出来，具体什么TFT对应哪一个ID，你可以去找一下战舰版的STM32的TFT程序，那里面有具体的内容，你看看就知道了，另外，驱动程序有的是厂家已经写好了，所以不是所有的都需要自己写

这个有点像ILI9325驱动程序
