FSMC驱动TFTLCD IC9806 点不亮，求助。

a982108962

用的F429TFTLCD（MUC屏）实验例程，和原子哥的链接方式只有两处不一样，1，我用的A16（PD11）作为RS。2，RST我接在PG9，开机后高1ms低10ms高120ms。
#define LCD_BASE        ((u32)(0x60000000 | 0x0001FFFE))

另外初始化代码是厂家给的，我后面就加了个清屏。LCD_Clear(0xF800)   红
用的还是原子哥的初始化FMC，没有修改。只是把引脚配置哪里RS从PD13改为PD11。

我写了一句while（1）LCD_WriteReg(0xF000,0x0055);  用示波器测RS有波形，WR有波，CS持续低，RD持续高。其他DB0-15在没有连错的情况下有的有信号，有的没有。
综上所述，还驱动不起来会是什么原因？CS任何时候都是低正常吗？

}
引脚配置，就把PD11改为PD13了。
