蓝牙音箱的空气放电ESD整改案例
     ESD空气放电,是指静电枪头没有直接接触金属,通过空气放电的方式注入PCB板上;按照实验标准的测试方法,对于孔缝等人体无法直接接触的端口进行空气放电实验。   一、描述:   本次实验产品是一款蓝牙音箱,其外露的端口主要有AUX,以及USB金属端口;AUX端口为塑胶,按照实验标准,对其进行空气放电8KV,在测试的时候,我们发现样机很容易会出现声音异常现象,并且无法正常关机,需直接断电

基于FPGA+MCU的大型LED显示屏系统设计
传统的大型LED显示屏系统以单片机MCU、ARM 或PLD为核心控制芯片,以FPGA为核心的led显示屏控制系统设计实现起来比较复杂,并且需要以高性能的FPGA芯片作为基础,而以微处理器为核心的LED显示屏控制系统不够灵活,在改变LED屏幕显示尺寸时,需要大幅修改系统设计,PLD虽在处理速度上有较大提高且能很好地控制多模块显示,但其在时序电路描述方面明显不如FPGA。提出了基于FPGA与单片机MC

永磁步进电机的识别经验和技巧
当需要识别未知的步进电机的特性时,我们有下列的建议,这些建议可以帮助大家快速、准确的识别步进电机。现在市场上常见的步进电机大多数是单极型、双极型或通用型。 我们先来认识一下这三种步进电机。 下图是一个单极步进电机。它有4极(两对线圈)定子和6齿永磁铁转子。每对线圈有一个中心抽头,它可能在电机内部连在一起,再用一根引线到外面,也有可能是用两根线单独引到外面。一般中心抽头接到电源正
