we are using rpi-gpio and node.js to read/write to raspberry version 1 pins. we have a led connected to gnd (pin 3) and gpio4 (pin 7). using write works perfectly: gpio.setup(7, gpio.DIR_OUT, write); function write() { gpio.write(7, true, function(err) { if (err) throw ...
板卡上主要包含: 1组DIP40接口 3组PMOD接口 1组RPi 40Pins接口 既可以插入小脚丫PCIE接口板卡使用,又可兼容树莓派扩展板卡与PMOD扩展模块,丰富了小脚丫核心板接口,提高了小脚丫板卡的兼容性。硬件说明板卡框图DIP40接口小脚丫系列中所有板子的大小兼容标准的DIP40封装,尺寸只有52mm x 18mm,双列直插引脚顺序统...
3. 那么RPi.GPIO在R2上是如何使用的呢? 3.1 首先在R2上面运行一个Ubuntu镜像,然后下载代码:git clonehttps://github.com/BPI-SINOVOIP/RPi.GPIO 这里如果不清楚如何安装一个Ubuntu镜像到R2,欢迎留言。 3.2 安装Python环境 1sudo apt-getupdate2sudo apt-getinstall python-dev python3-dev ...

1、从 RPi.GPIO 迁移 - Migrating from RPi.GPIO If you are familiar with the RPi.GPIO library, you will be used to writing code which deals with pins and the state of pins. You will see from the examples in this documentation that we generally refer to things like LEDs and Buttons rathe...
