树莓派通过I2C接口可控制多个传感器和组件。它们的通信是通过SDA(数据引脚)和SCL(时钟速度引脚)来完成的。每个从设备都有一个唯一的地址,允许与许多设备间快速通信。ID_EEPROM引脚也是I2C协议,它用于与HATs通信。 SPI是串行外设接口,用于控制具有主从关系的组件,采用从进主出和主进从出的方式工作,树莓派上SPI由SCLK...

pi-gpio is a simple node.js based library to help access the GPIO of the Raspberry Pi (Debian Wheezy). It's modelled loosely around the built-in fs module. It works with:original Raspberry Pi (A and B) model B revision 2 boards Raspberry Pi Model A+ Raspberry Pi Model B+var...
Export elegant OOP APIs to control Raspberry Pi GPIO pins with Node.js. Based onnode-rpiowhich is a high performace library. Installation npm install rpio2 --production By default the module will use/dev/gpiomemwhen using simple GPIO access. To access this device, your user will need to ...
我们去使用GPIO子系统时,首先是获得某个引脚对应的gpio_desc。 gpio_device表示一个GPIO Controller,里面支持多个GPIO。 在gpio_device中有一个gpio_desc数组,每一引脚有一项gpio_desc。 3. 怎么编写GPIO Controller驱动程序 分配、设置、注册gpioc_chip结构体,示例:drivers\gpio\gpio-74x164.c ...
