The Design Scheme Of New Type Muti-function Bluetooth Sound Box Based On AU6210

This paper proposes a design scheme of multi-functional bluetooth speakersbased on AU6210chip.The speaker has play function which traditional speakerowns.At the same time, it has powerful functions such as RTC, alarm, headphones,infrared remote control, bluetooth, Mobile-phone. It has small volume so that it canbe easy carried. And it runs by battery without power supply. Characteristics andhistory of the traditional speakers are elaborated in details.The traditional speakerwill compare with the new bluetooth speaker in the aspects of humanity, operability,convenience. The advantages and disadvantages between them will be discussed.In the paper, a new type of multifunctional design of bluetooth speakers basedon AU6210chip was introduced from the aspects such as hardware, software,debugging. First of all, the hardware aspect, the author introduces thecharacteristics of main control chip AU6210and compare to other chips.The paperintroduces the species of external AU6210module and show how it works, one byone. Secondly, the software aspect,according to customer’s demand, Introduced theprocess of software development in the aspects of program functionrequirement, the effect of the operation which users should achieve, Initializationmodule function about on and off, GPIO port initialization, how to write programabout the bluetooth module and scanner LED screen. Finally, after completion ofthe hardware and software, the paper introduces the debugging work. Debug mode,method and tools is described in detail.Introduce the mistakes and solutions whichhave appeared in the process debegging. Show what should be careful in the aspectof software writing in order to avoid errors. And this paper disc usses the feasibilityof scheme.
