【晒样片】 TI设计套装-用于2 线、4 到 20 mA 电流环路系统
【晒样片】TI设计套装-第二期(工业应用)-RTD温度发送器参考设计:用于2线、4到20mA电流环路系统前段时间刚好做了个温控板,一个是为了学习一下PID控制,另外朋友刚好需要做这样个东西,所以就做了块板,控制用NXP的LPC1114,温度传感器用的是MAX6675,SPI接口的K型温度传感器,效果还可以,刚好看到这个EEWORLD的这个活动,所以想申请几个TI的芯片再玩玩由于活动页面中的几个芯片我不需要,所以我就点TI设计套装中去找需要的电池(锂离子)保护解决方...

使用BBB的ADC
本帖最后由wytalfred于2014-3-821:49编辑 BeagleboneBlack的处理器芯片AM3359上的8个ADC脚同时也是触摸屏控制器(TSC),我们知道一般的电阻屏分为4线、5线或8线的,除去触摸屏以外的ADC接口可以作为普通的ADC使用。(我们在查询TI公司的4000页AM33xx手册时需要到TouchscreenController这一章去找有关ADC的内容。)特别注意:BeagleboneBlack的ADC管脚最大只能输入1.8V!!!...

TMC2208测试(问题排查)
TMC2208测试报告目录1.问题回顾2.测试平台展示3.针对性测试3.1.待机电流特性3.2.匀速过程电流特性4.总结 问题回顾 在上次测试中,主要对待机电流,微步的平滑度,电机加速/减速等进行测试,通过测试出的相电流波形不难看出电流波形圆滑,也不存在畸变的情况。但是保持电流的波动较大,匀速阶段也存在些许毛刺。初步推断是由于杜邦线的原因,为此我又进行了测试。 测试平台展示 本次测试和上次使用的平台一样,唯一的区别是将对接杜邦线改为新的单...
