学习RPi + GPIO + node.js 基本的HOWTO使用nodejs在Raspberry Pi中使用GPIO引脚进行操作: 注意,您必须安装一个额外的软件包才能使pi-gpio正常工作(请参阅上面的链接)。 在接地和引脚7(在板上标记为“#4”)之间连接一个LED和一个电阻器,或者仅更改所用引脚的变量。
def cleanup(self): ''' Cleans the GPIO resources ''' The main method is move, which moves the motor the desired number of steps steps property It's possible to check the motor position or manually set the desired step using the steps property: import RPistepper as stp M1_pins = [17,...
Pinout.xyzcan be very useful to determine the correct GPIO line for the relais (2 is the one that is assumed in all the images above). We are using the assignments fromlibgpiod. Also, thegpioinfocommand is very useful in that regard. ...
简单理解就是树莓派上的 40 个GPIO 接口每一个都有两个名字,一个大名,一个小名,虽然叫法不一样,但是指代的接口都是同一个。 如果是用来接线的话,看 Board 序号可能更好找一点。如果不知道 BCM 和 Board 之间的对应关系时,也可以直接在树莓派中输入如下命令来查看: pinout 知道如何分辨树莓派上的接口后,我们...
