LCD12864的串行驱动程序，采用MSP430F149作为微处理器。调试的时候由于IO口不足，无法用并行的方式连接液晶，用串行方式连接，只占用两个普通的IO端口，节省资源。环境是IAR,并采用模块化编程，方便移植到其他的集成开发环境中。

必须校准系统,校准方法，如下：将7455平放，保证z轴向下，这是如果系统是Ok的，那么x轴输出为0，y轴输出为0，z轴输出为63左右，如果不为以上参数，应该做如下调整：测量值比实际值小的情况下，往校准寄存器里面写入一个2*误差值； 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

应用背景Verilog语言编写的ddr2控制器，主要通过控制ddr2的用户侧界面控制ddr2的读写，本程序主要完成一次简单的写地址，写数据到ddr2里，并且再写地址，读数据回来，以此校验ddr2的读写。关键技术通过在xilinx ise工具里进行综合仿真，并且在xilinx v5 110t板子上成功实现读写。通过控制用户侧界面的ap_af_addr,app_wdf_addr,等app信号写进ddr2控制器里，在读回read_data_fifo信号
