基于单片机及nRF2401的无线通信模块(2)

Abstract

This paper introduces a design AT89S52 single chip control with the core of wireless communication control module design system, detailed instructions on the system of basic principle, hardware frame, main circuit and software frame. The whole system uses modular design, including between microcontroller and lower level computer wireless communication control circuit, and wireless communication module with PC based on serial interface between the RS-232 standard serial communication interface circuit and USB high-speed communication interface circuit. This communication control system through the PC's RS-232 serial communication and USB high-speed communications, thus through wireless communication control module formation and lower level computer connection, control, and a machine motion controller will receive data storage to communication within the memory expansion.

This module communication method is simple, remoting real-time control outside, still can be widely used in industrial supervisory control and data acquisition system. This system has reliable performance, strong anti-jamming capability, low power consumption, high performance-to-price advantages in wireless communication domain, has important application value and good development prospect.
