j1939在康明斯电控发动机上的应用情况和基本概念(j1939 electronically controlled Cummins engine in the application and basic concepts)

采用载波移相技术和PR控制器的STATCOM仿真(Carrier phase shift technique H bridge cascade is simulated by STATCOM PR controller)

说明：  此应用笔记收集了用软件实现的主模式SPI程序。提供了8 个不同的SPI 主模式传输例。示例中包含SPI时钟相位和极性两个子例程：一个是用C 语言编写的例程，一个是为了提高速度用汇编语言编写的可被C 语言调用的例程。一个例子是在“C”程序中如何调用汇编同时提供了EEPROM接口例子。SPI是摩托罗拉商标。 此文档中描述的SPI功能使SPI处理的软件 最小化。在系统中使用C8051F30X 器件作为 总线上的SPI 主器件。(This application note collection implemented in software SPI master mode procedures. Provides 8 different SPI master mode transfer cases. Examples include SPI clock phase and polarity of the two sub-routines: one is written in C language routines, one is to increase the speed of assembly language written in C language can be called routine. One example is in the &quot C&quot programs how to call assembly also provides examples of EEPROM Interface. SPI is a Motorola trademark. SPI described in this document processing software capabilities to minimize the SPI. In the system C8051F30X SPI device as the primary device on the bus.)
