gcc -Wall -o gpio_led gpio_led.c -lwiringPi 1. 成功编译后会在当前目录下生成一个名为gpio_led的文件,使用 sudo ./gpio_led命令即可运行程序,当然你不想程序运行了也可以使用Ctrl+C结束程序运行。 用BCM2835 C Library实现 同样新建一个名为gpio_led.c的程序文件,然后输入如下程序内容: 纯文本查看 复...
自己摸索了一下,实现简单的GPIO控制方法,作者的Zero安装的是Armbian系统,使用python写了一个读写寄存器的简单模块,通过这个模块,即可实现对GPIO的控制。 作者以前使用过STM32的MCU,这类MCU,如果要实现对GPIO的控制,只需要根据datasheet查找相应GPIO寄存器并进行配置,即可实现IO控制,例如,要将内存地址为0x12345678的寄存器...
GPIO Zero supports a number of different pin implementations (low-level pin libraries which deal with the GPIO pins directly). By default, theRPi.GPIOlibrary is used (assuming it is installed on your system), but you can optionally specify one to use. For more information, see theAPI - Pi...
7.2、删除dt_python_demo.c中 #include "wifiiot_gpio.h"#include "wifiiot_gpio_ex.h"#include "wifiiot_pwm.h"7.3、修改applications/sample/wifi-iot/app/BUILD.gn文件：lite_component("app") { features = [ "demo:python", ]} 7.4、将libpython.a添加到W800 Makefile中。8、编译，...
在这种情况下,所有的引用都必须带上 GPIO Zero 库前缀: button = gpiozero.Button(2) (2)针脚编号 - Pin Numbering This library uses Broadcom (BCM) pin numbering for the GPIO pins, as opposed to physical (BOARD) numbering. Unlike in the RPi.GPIO library, this is not configurable. However, tr...
Jetson TX1, TX2, AGX Xavier, and Nano development boards contain a 40 pin GPIO header, similar to the 40 pin header in the Raspberry Pi. These GPIOs can be controlled for digital input and output using the Python library provided in the Jetson GPIO Library package. The library has the sa...

最近入手OrangePi Zero一块,程序上需要使用板子上自带的LED灯,在网上一查,不得不说OPi的支持跟树莓派无法相比。自己摸索了一下,实现简单的GPIO控制方法,作者的Zero安装的是Armbian系统,使用python写了一个读写寄存器的简单模块,通过这个模块,即可实现对GPIO的控制。
Jetson TX1,TX2,TX2 NX,AGX Xavier和Nano开发板包含一个40引脚GPIO接头,类似于Raspberry Pi中的40引脚接头。可以使用Jetson GPIO Library包中提供的Python库来控制这些GPIO的数字输入和输出。该库与Raspberry Pi的RPi.GPIO库具有相同的API,以便提供一种将Raspberry Pi上运行的应用程序移动到Jetson板的简便方法。 包装组...
