High Precision Data Collector Based on PIC Single Chip

Abstract

介绍利用PIC单片机对24位的Δ ∑模数转换芯片进行应用而开发的一种通用高精度数据采集器。具体介绍了数据采 集器中的A/D转换芯片的工作原理,PIC单片机的通讯模块,实现数据采集工作的相应电路及程序流程图。In this paper, a common high precision data collector which uses PIC microchip to control the 24 bit Δ-∑ A/D converter is introduced. The principle of A/D converter, the communicating block of PIC microchip, the corresponding circuit and the flowchart are introduced in detail
