PWM

单片微型计算机简称单片机，是典型的嵌入式微控制器（Microcontroller Unit）， 单片机芯片 常用英文字母的缩写MCU表示单片机，单片机又称单片微控制器，它不是完成某一个逻辑功能的芯片，而是把一个计算机系统集成到一个芯片上。(Microcontroller chip microcomputer referred to, is a typical embedded microcontroller (Microcontroller Unit),     Single chip Commonly used letters of the abbreviation indicates MCU microcontroller, microcontroller, also known as single-chip microcontroller, it is not complete a certain logic functions of the chip, but to a computer system integrated into a single chip.)

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.
