The Design And Implementation Of Wireless Audio And Video Acquisition And Transmission System Based On CC3200

Nowadays microprocessor aiming at the realization of the Internet of Things has coming out frequently.In this paper,we have chosen CC3200,TI's industry-leading embedded microcontroller,which integrates the ARM Cortex-M4 core and the WiFi network subsystem,to study.The microprocessor is designed to replace the previous single-chip and WiFi-enabled transceivers to achieve the development of embedded products for the Internet of Things.Based on the study of CC3200 MCU,this paper encapsulates the CC3200 peripherals UART,I2 C,I2S,uDMA,and so on,which reduces the difficulty of controlling through peripherals and enhance the user friendliness of development based on CC3200.On that condition,a CC3200-based wireless audio transmission system is designed and developed.The system,CC3200 as the master chip and TLV320AIC3243 for the audio codec,has not only achieved the local recording and playback of audio,but also accomplished the feature of recording in an end and playback in the other under the use of WiFi communication.This article has prepared the camera MT9D111 driver,configuring it for video acquisition and saving as JPEG format,based on which we have designed and developed a CC3200-based wireless vedio transmission system.The client connects to the CC3200 configured as the Http Server through WiFi and you can use the browser in your smart device to browse the video data stored in the CC3200 SFLASH.Finally,the functional test of the above two systems is presented.The test results show that the wireless audio transmission system and video transmission system based on CC3200 are working normally,which basically realizes the development of the expection and has provided a reference for related solutions in the area of the Internet of Things and even the Intelligent Home.
