这打开关闭触摸开关电路基于众所周知的计时器 IC 555 (IC1) 驱动器就像一个开关继电器。金属表面可以有何种的形式，我们想要的但它应该是干净，非常接近的电路。 触摸板 MP1 为了接触继电器 RL1 [关于]，或以打开该联系人 RL1 板 MP2 [关]。带领 D2 亮起时的 RL1 触点闭合。两个小的金属片可以用作传感器板。 555 打开/关闭触摸开关示意图 组件列

应用背景在STM32F105和STM32F107互连型系列微控制器之前，意法半导体已经推出STM32基本型系列、增强型系列、USB基本型系列、互补型系列；新系列产品沿用增强型系列的72MHz处理频率。内存包括64KB到256KB闪存和 20KB到64KB嵌入式SRAM。新系列采用LQFP64、LQFP100和LFBGA100三种封装，不同的封装保持引脚排列一致性，结合STM32平台的设计理念，开发人员通过选择产品可重新优化功能、存储器、性能和引脚数量，以最小的硬件变化来满足个性化的应用需求。关键技术本实验将实现如下功能：开机先检测字库是否存在，如果检测无问题，则对VS1053进行RAM测试和正弦测试，测试完后开始循环播放SD卡MUSIC文件夹里面的歌曲（必须在SD卡
