摘要
同步串行接口具有传输速度快、抗干扰能力强等特点,在具有串行数据传输的电子设备中得到了广泛的应用。同步串行数据的接收需要专用芯片,这使得具有同步串行接口的电子设备的应用受到了限制。针对具有同步串行接口的绝对值编码器,提出了串行数据转换和读取的实现方法,给出了详细的硬件原理图及其电路设计要点,并提供了关键的软件代码。这为具有同步串行接口设备的数据并行采集提供了一种低成本的实现方案。
Synchronous serial interface has been widely used in electronic equipment with serial data transmission because of its features of high transmission speed and strong anti-interference capability. Since dedicated chip is needed for receiving synchronous serial data,the application of electronic equipment with synchronous serial interface is limited. Aiming at the absolute value encoder with synchronous serial interface,the implementing method of serial to parallel data conversion and reading is proposed. The detail hardware schematic diagram and key points of circuit design are given,and the critical software coding is provided. This offers the low cost implementing scheme of data parallel acquisition for synchronous serial interface devices.
