The design of Music recording device Based on STM32
Abstract
Along with the rapid development of electronic industry，and people is growing consumer demand on the electronic technology products, which portable multifunction MP3 has become popular with consumers increasingly because of its compact and lightweight. The design of music playback Based on STM32 mainly uses the ARM Cortex-M3 core and STM32F103ZET6 as the central control processor, SD card as the storage medium, VS1053 audio decoder chip as well as a music display TFT Display screen equipment.It can play mp3, wav or other file formats and to achieve a portable music playback-related functions such as recording and playback. The design introduces the STM32 minimum system works, read mode of SD cards, VS1053 audio decoder chip process，the control operation method of TFT man-machine interactive equipment and the way of dredging collaterals between the main and subordinate machines. And it also designs the electrical schematic diagram of recording systems and the hardware board circuit, to achieve a record / playback, loop / repeat play, select Play function, to achieve display and interactive features by using the TFT Display screen.
