80MHz 12 bit ADC processor LPC4370.LPCxpresso do a LPC LINK2 and LABTOOLS open source oscilloscope demo set. (£84 from Mouser, seems quite well liked.) The LPC LINK2 is £14 + VAT from Mouser, it has the ADC on board. The Lab tools board has signal co…

驱动能力 电源驱动能力 -> 输出电流能力 -> 输出电阻 指输出电流的能力,比如芯片的IO在高电平时的最大输出电流是4mA -> 该IO口的驱动驱动能力为4mA 负载过大(小电阻) -> 负载电流超过其最大输出电流 -> 驱动能力不足 -> 输出电压下降 -> 逻辑电路无法保持高电平 -> 逻辑混乱 XX 一般说驱动能力不足是指某个IO口/引脚无法直接用高电平驱动某个外设,需要加三级管(驱动脚由三极管的发射极或集电极提供)或者MOS管. IO与输出电流 单…

在Web前端开发中,我们经常会遇见需要动态的将一些来自后端或者是动态拼接的HTML字符串绑定到页面DOM显示,特别是在内容管理系统(CMS:是Content Management System的缩写),这样的需求,更是遍地皆是. 对于对angular的读者肯定首先会想到ngBindHtml,对,angular为我们提供了这个指令来动态绑定HTML,它会将计算出来的表达式结果用innerHTML绑定到DOM.但是,问题并不是这么简单.在Web安全中XSS(Cross-site scripting,…
