基于手机蓝牙与FPGA的多功能琴键设计

Multifunctional keyboard design based on bluetooth and FPGA

在大众生活环境和质量普遍改善、业余文化生活需求不断提升的情况下,人们对电子琴系统设计的要求也越来越高。本文介绍了一种手机蓝牙与FPGA的多功能琴键设计方法,可实现手机蓝牙触屏控制弹奏的暂停与启动,也可通过蓝牙模块传输音乐到手机存储、回放。蓝牙模块HC-05负责接收无线数据并交由FPGA处理。用户通过操作安卓APP界面按钮实现对Lattice可编程FPGA多功能琴键进行无线控制。设计具有一定的实用价值。

With the general improvement of the living environment and quality of the public,people have higher and higher requirements for the design of electronic organ system.This paper introduces a design method of multifunctional keyboard for bluetooth and FPGA, which can control the pause and start of playing by bluetooth touch screen and transmit music to mobile phone storage and playback by bluetooth module. The bluetooth module HC-05 receives wireless data transmission to the FPGA for processing.Through the APP interface buttons, the user realizes the wireless control of the Lattice programmable FPGA multifunctional keyboard.The design has certain practical value.
