与8051微处理器生成3线信号使用多个DS1267数字电位器

资料介绍
摘要: DS1267是一个双串行移位寄存器“型接口的数字电位器。移位寄存器的数据移入输入引脚以及转移的最后一位移位寄存器被写入时的数据输出引脚。这允许多个DS1267s菊花链连接在一起,并在同一串行总线编程。本应用笔记介绍了如何完成这个电路实例和伪代码例子展示了如何开发任何微处理器的代码。

APPLICATION NOTE 409
Using Multiple DS1267 Digital Potentiometers With an 8051
Microprocessor Generating 3-Wire Signals

Abstract: The DS1267 is a dual digital potentiometer with a serial "shift register" type interface. The shift
register has an input pin where data is shifted in as well as an output pin which shifts data out of the last bit of
the shift register when being written. This allows multiple DS1267s to be daisy-chained together and
programmed together on the same serial bus. The application note describes how to accomplish this with circuit
examples and pseudo code examples showing ……
