STM32 使用 SPI_DMA 实现两台计算机之间的高速通信方式

这个源代码实现了51单片机多路舵机同时控制程序，已通过测试

主要涉及ad7799寄存器的读写，各种寄存器的配置-read and write of ad7799 register

应用背景ADXL345 是AD 公司的一款 3轴、数字输出的加速度传感器。stm32驱动该传感器进行通信和获得数据。关键技术功能简介：主函数不停的查询ADXL345的转换结果，得到x、y和z三个方向的加速度值（读数值），然后将其转换为与自然系坐标的角度，并将结果在LCD模块上显示出来。DS0来指示程序正在运行，通过按下WK_UP按键，可以进行ADXL345的自动校准（DS1用于提示正在校准）。
