| Abstract: | By using ＂Yixian Tong＂, the USB broadcast playing and controlling system is designed, in which the whole external equipment is linked to the main controlling computer by only one USB cable. Thus its structure is simplified and its reliability improved. This paper describes in detail the hardware circuit design and software module programming, including the designs of the interface circuit, control circuit, analog-digital and digital-analog conversion circuit, FM circuit, and the programming of the USB firmware, USB driver routine, playing and controlling window procedure. The system is functionally powerful and quite cost-effective. It has broad market prospects in the small radio stations of various schools, enterprises and public institutions. |
