由于寄存器方式需要学习的太多，只好采用现成的函数编写程序。
首先实验128x64.dot的黑白LCD，这款用的焦躁，其中的初始化LCD程序已能在多款类似芯片下成功显示。
此次驱显得是类0108芯片的LCD。采用两款：大屏幕的和小屏幕的，尽管芯片不同，但采用0108 驱动都正常，仅仅是在控制电压上改改而已。
按照原GPIO程序中的口定义函数，将PORTD0~D3定义为输出方式，以控制4线制的LCD。
定义如下：
选择I/O口：
IO_FUN_SEL(MKL_PORTD,0,1);//LCD Clock
IO_FUN_SEL(MKL_PORTD,1,1);//LCD Data
IO_FUN_SEL(MKL_PORTD,2,1);//Cmd:1=Data & 0=Command
IO_FUN_SEL(MKL_PORTD,3,1);//Reset LCD
定义为输出I/O口：
GPIO_DDR_OUTPUT(MKL_PORTD,0);//LCD Clock
GPIO_DDR_OUTPUT(MKL_PORTD,1);//LCD Data
GPIO_DDR_OUTPUT(MKL_PORTD,2);//Cmd:1=Data & 0=Command
GPIO_DDR_OUTPUT(MKL_PORTD,3);//Reset LCD:- Enable

其中
LCD Clock为LCD写时钟，下沿有效
LCD Data为LCD数据，保持后由Clock锁存
Cmd:1=Data & 0=Command为命令数据描述，1写入LCD的是数据，0写入的是控制命令
Reset LCD为LCD复原信号，0有效，1还原。
说明：经过测试，LCD Select chip set——cs信号用处不大，只有这个LCD，省略了。
将以前在M051上成功运行显示符号的程序改吧改吧直接移过来，就Ok了。

主程序中的系统时钟等照旧，只是增加了LCD显示部分。dispOut()，以及将8位字符转成1bit写入LCD的相关程序先不给出，希望先自己尝试编程。上述LCD初始化之后，LCD屏幕应该能看到变化的，说明已能控制LCD了。过几天忙完后给出完整程序。
