Foreword
The use of reprogrammable memory technology in vehicle electronic control units (ECUs) has increased
in recent years, and is expected to continue in the future. Use of this technology has increased the
flexibility of being able to use a single ECU hardware part to be used in many different vehicle
configurations, with the only difference being the software and calibrations programmed into the unit.
Reprogramming of those ECUs in the service environment also allows for ease of field modification of
system operation and calibrations. Variations in reprogramming capability and the multiple tools
necessary to reprogram vehicles are a burden on aftermarket repair facilities that service different makes
of vehicles.

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)

滤波器广泛应用于数字信号处理、通信、自动控制领域,但设计可变宽频带有源滤波器则比较困难。利用单片机控制参数可编程的双二阶通用开关电容有源滤波器,精确设置有源滤波器的中心频率f，品质因数Q及有源滤波器的工作方式。本系统主要分为两个部分:即程控滤波器和程控放大器。程控放大器电压增益为40dB，通过单片机控制DA进行分压，可精确实现要求的10dB步进，误差小于0.5 ，通带为100Hz-500KHz，输入电压峰－峰值范围为10mV，在输入范围内无明显失真。由MAX264为核心的滤波器，可设置为高通、低通滤波器。通过单片机直接给出控制频率，使-3dB截止频率在1KHz-20KHz内可调，步进1KHz，误差小于1 。整个系统以52单片机为控制核心，电路简单，性能稳定，且具有较高精度，滤波参数调节通过单片机控制，较为方便。(Filters are widely used in digital signal processing, communications, automatic control area, but the design variable wideband active filter is more difficult. Control parameters using single-chip programmable universal switched-capacitor biquad active filter, active filter accurately set the center frequency f, quality factor Q and the active filter works. The system is mainly divided into two parts: the program-controlled filters and programmable amplifiers. Programmable amplifier voltage gain of 40dB, the DA through the partial pressure of single-chip control, can accurately achieve the required 10dB step, the error is less than 0.5 , passband to 100Hz-500KHz, input voltage peak- the range of 10mV, the input range no significant distortion. By the MAX264 as the core of filter can be set to high pass, low pass filter. Given directly by the microcontroller controls the frequency, the-3dB cutoff frequency at 1KHz-20KHz adjustable, step 1KHz, error is less than 1 . The entire system for)
