解析单片机攻防技术与防御措施
<p>电子设备的单片机执行程序一般都是基于仿真器进行下载,储存于芯片内部。就模块级设备而言,其主要是由于单片机与DSP芯片结合设计,单片机可以衔接仿真器,以JTAG接口为辅助直接性读取,保存执行代码。此设计方式的风险性较高,尽管只是利用仿真器读取执行代码,但是随单片机破解技术的更新发展,应针对单片机自身采取有效的防御性措施。据此,本文主要对单片机攻防技术与防御措施进行了详细分析。</p><p>Th
智能数字音乐盒的设计与实现
<p>随着科技的飞速发展,人们的生活节奏越来越快,多数人长期处于压力过大的状态。音乐对于调节人的心理压力来说是一种很有效的方式,因此,各式各样的音乐盒开始普及。由于容量大、操作方便、价格便宜等优点,数字音乐盒逐渐成为人们的首选。这里以电子技术为基础,设计了一款数字音乐盒。它以单片机为核心,主要由外围控制电路、外接电路、发声电路、电源电路等组成整个系统。音乐的播放可用按键或者红外遥控器实现,同时还可
