开发工具 Arduino学习笔记4_Arduino软件模拟PWM
注:1.这篇文章断断续续写了很久,画图技术也不精,难免错漏,大家凑合看.有问题可以留言.
     2.论坛排版把我的代码缩进全弄没了,大家将代码粘贴到arduino编译器,然后按ctrl+T重新格式化代码格式即可看的舒服.
一、什么是PWM
PWM 即Pulse Wavelength Modulation 脉宽调制波,通过调整输出信号占空 ...
开发工具 Arduino应用_Arduino连接超声波传感器测距
超声波传感器适用于对大幅的平面进行静止测距。普通的超声波传感器测距范围大概是 2cm~450cm,分辨率3mm(淘宝卖家说的,笔者测试环境没那么好,个人实测比较稳定的 距离10cm~2m 左右,超过此距离就经常有偶然不准确的情况发生了,当然不排除笔者技术 问题。)
测试对象是淘宝上面最便宜的SRF-04 超声波传感器,有四个脚 ...

可编程逻辑 Create a 1-Wire Master with Xilinx PicoBlaze
Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wir ...
可编程逻辑 HDB3编解码器设计
HDB3(High Density Bipolar三阶高密度双极性)码是在AMI码的基础上改进的一种双极性归零码,它除具有AMI码功率谱中无直流分量,可进行差错自检等优点外,还克服了AMI码当信息中出现连“0”码时定时提取困难的缺点,而且HDB3码频谱能量主要集中在基波频率以下,占用频带较窄,是ITU-TG.703推荐的PCM基群、二次群和 ...
