数据采集系统 MAX1403.C 该文件是用于MAX1403的代码，包含了McBSP初始化、MAX1403初始化、McBSP读写等函数，读者可加入自己的工程之中去，并根据自己的要求适量修改之。 TLC5510A.C 该文件是用来驱动TLC5510A的代码，由于TLC5510A是总线型的高速AD，其访问较为简单，访问的方法及细节请见本书第17章。 MAX5444.C 该文件是驱动MAX5444的代码，由于MAX5444是单路高精度DA，所以，代码中只需执行系统初始化、McBSP初始化之后即可对MAX5444进行写数据操作，从而输出电压值。 AD7541A.C 该文件是驱动AD7541A的代码，AD7541A是总线型的高速DA，其访问方式如同片外RAM一样，请参考本书第17章的介绍 pdf 文件是“数据采集系统”的电路图实例，本电路图注重于高速AD、高精度AD、高速DA、高精度DA的连接方法以及外围电路设计，为读者朋友提供一个完整的电路实例。而C6713电路部分，只涉及C6713与四个AD/DA器件的连接关系，至于C6713的其他部分（如SDRAM、FLASH等）都略去,读者可参考另外相关的章节。(Data Acquisition System)

步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
