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 ...
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 3.3 安装中间件 ...
gpio gpio_open_device(unsigned int device) Returns a handle to an AXI GPIO controller based either on the base address or device index. The handle will allow for all pins on channel 1 to be set simultaneously. gpio gpio_configure(gpio parent, int low, int hi, int channel) ...

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...
