碩士 === 樹德科技大學 === 電腦與通訊系碩士班 === 101 === In this thesis, the research investigates the characteristics of the chips or modules such as A7125 wireless chips by AMICCOM Tech., 8051 microprocessor chips and Bluetooth modules. The study covers the interface and connection between these hardwares, which are driven and programmed using C language. The first part of this thesis introduces the RF circuit development and production, which focus on the reception and transmission of the RF wireless connections. The circuits design comprises the passive and the active circuits, e.g. the FM antenna for the passive circuits, and frequency tracing algorithm design for active circuits. The second part is the Bluetooth module application and development. The design system applies APP inventor by MIT for android software developing and C language for microprocessor firmware program. The system architecture uses PCB substrate for integrated circuit layout and elements deployed. The APP program subjects on the signal control between the built-in Bluetooth module in smart phones and the Bluetooth module of the designed wireless timer system. The third part focuses on the development for the A7125 radio frequency chip applications. In this part, the research subjects on the C programs development for the responder machine, which was previously programed using assembly language. The advantages of the C programming include easy debugging, readability for features add to improve functions, and reduction of the probability causing loop disorder phenomenon.
