MC9S08AC08 SPI驱动LCD5110

正在用S08的片子开发BLDC驱动器，闲着无事献上自己S08驱动5110显示屏的程序，发现S08的SPI还是相当的靠谱（IIC调试了两天都没搞好），看参考手册写完代码，编译无错误，上电LCD就点亮了，显示也很正常，下一步把IIC调好，不知道有对S08上的IIC有调试心得的没！下面附上SPI部分的代码，详细见附件里面的文件，主要在CW10.6里面开发的，在CW6.3里面编译的话可能会出现头文件错误（无赖电脑CW6.3一直装不上去，虚拟机里面用的也相当无语，只好选择CW10.6），貌似TBDM/OSBDM在CW10.6中都是无法调试的，自己做了一个简单的USBDM，在CW10.6里面完美调试。
