                                 ILI8325初始化代码 可以用GPIO直接驱动，应该没有问题 所以省略了

                                 高人指点一下吧

                                 LZ是对FSMC的配置存在疑问吗？

huh1012

                                 ILI9325的初始化程序使用GPIO直接驱动是正确的 应该只可能是FSMC的配置有问题了吧...

最好用示波器看看波形对不对。

也可以改改参数试试（把时序改慢点），把下面参数都改成 15：
p.FSMC_AddressSetupTime = 2;  
  p.FSMC_AddressHoldTime = 1;  
  p.FSMC_DataSetupTime = 5;

哎 没有示波器 可怜啊~
CS信号 自己控制的时候 显示正常
如果把CS信号交给FSMC控制 就没显示了
但是这三个参数也试了不少了....都一样不显示

还是靠自己....
终于搞定了
