【原创】R61509/SPFD5420A驱动调试总结

 
这贴为了回应上一次在WINCE区被转走的一个帖子。调试了半个月终于把屏完全调好了。
呵呵。累啊。

環境：wince5.0
cpu：ARM920T Anyka7802
玻璃：LG liquid crystal panel
Driver IC：R61509/SPFD5420A 可以互相替代
通讯：并行16bit命令 并行18bit数据
其他：i80SYSTEM 18BIT-262


下面给出初始化的code

     {END_FLAG, END_FLAG}

有调试这个屏IC的朋友可以参考下。呵呵。
注意R400H寄存器。另外我这里旋转了270度。屏旋转注意R003H寄存器。

有关于基于WINCE+屏调试的问题大家可以互相沟通。

关键的寄存器 R003H R400H R401H R402H.
