The Design Of Digital Mixing Console Channel Module Based On MSP430

As the development of digitalization, the developing ang manufacturing of digital mixing console has been paid more and more attention. The transmission of digital signal can obviously decrease attenuation and anti-jamming. It is useful to make a transition from analog mixing console to digital mixing console, and the digital ones have become the preferred mixing console. There are not problems on timbre ant more, the interface of live mixing consoles has become more and more flexible, and the UI of these ones has become much User-friendlier. Nowadays, in the developed countries, with the development of network for live mixing consoles, the broadcasting station audio-systems which contain mixing console have become internet-oriented; it is beneficial that we can optimize the management of database and other resource.This paper designs the new generation digital mixing console. It is one product which unifies the embedded system technology and the digital mixing console, is a section of novel intellectualized the network third generation product. It not only realizes the digitization in mixing console's internal each kind of signal's processing, but also introduces the embedded operating system, causes mixing console's function becomes more formidable, the contact surface is also friendlier, the control is also easier, moreover may meet each kind of personalized need. Fast develops now again the embedded system technology applies the digital mixing console's design, causes the mixing console modulation, the network and the intellectualization, has the widespread use value and the huge practical significanceFirstly, this thesis introduces the development and the domestic or overseas status in quo; in succession, it explain the configuration and characteristic of digital mixing console and illuminates the module partition of entire system, we can divide the system into three portions: audio-processing module, host control module and channel module; afterward, it summarizes the system's design and existent problems. In the process of design, given the communication among channel sub-modules or between host control module and channel sub-modules, this thesis refers to the local bus such as CAN(Control Area Network) Bus, furthermore, it also design abundantly peripheral interface which can provide more and more humanistic operation on digital mixing console with users.This article designs the digital mixing console channel module, achieves the demand parameters, the single device debugging passes, with the master control module, is accused the module debugging on-line to pass, the prototypical production debugging completes. But the application procedure also waits for further consummating, because the first digital mixing console uses in the television station, broadcasting station's live program , safe and stable are the most important consideration questions, the digital mixing console the question which halts the phenomenon is needs to try to solve. The next this article designs the OLED display monitor size is small, next step must improve, and adds on the graphical display contact surface to the system, causes the operation user-friendly.
