电子琴原理 什么是声音?上过初中的朋友都知道声音是由震动所产生的.一定频率的震动就产生了一定频率的声音. 理论研究第一步,让喇叭发出do re mi fa sol la si的音,我们先不管do的频率是不是261hz,更重要的是我们必须知道,每个音之间的频率关系,初中老师说,do re mi这三个音相邻两个音是全音关系,mi 和 fa 是半音关系,fa sol la si 这四个音相邻两个音也是全音关系.全音关系意味着振动频率关系为2的开六次方,即1.12246,半音关系意味着频率关系为2的开1
The LatticeMico System software is composed of three bundled applications: Mico System Builder (MSB) C/C++ Software Project Environment (C/C++ SPE) Deployment 设计流程: 1.创建一个diamond目标器件的工程,注意综合工具手册要求 2.使用MSB创建一个微控制器平台,添加core,选取所需外设,定义连接.组合好一个MCU.
