OrangePi ZERO 2 peripheral application development ultrasonic module (HC-SR04)

The distance measurement function can be achieved using the HC-SR04 ultrasonic distance sensor, which can measure the range of objects up to 13 feet (approximately 3.96 meters). They have low power consumption (good for battery-operated devices), are cheap, easy to connect, and are insanely popular among hobbyists. Plus, it even looks cool, like a pair […]

OrangePi ZERO 2 peripheral application development using wiringOP programming to light up an LED and shell script compilation

This article is a C/C++ programming tutorial based on the installation of the wiringOP library. It does not introduce the functions in the wiringOP library uniformly, but explains the usage and meaning of the functions based on the usage scenarios. 1. Create a new .c file The LED used by the blogger is a board […]

Orange Pie cooperates with IIC to drive OLED & uses SourceInsight to interpret the source code

OLED screen introduction & amp; hardware wiring OLED is also an old acquaintance. For a detailed introduction, see: IIC protocol and OLED_iic oled-CSDN Blog Review the Orange Pie hardware wiring again: According to previous studies, I learned that OLED screen drivers require the IIC protocol. When learning C52, I used code to simulate the IIC […]

ubuntu22.04 builds orangepi5plus development environment

Building the development environment of orangepi5plus can be said to be full of twists and turns. For this reason, I summarized a script file to fully automatically build the environment. buiild_env_5p_driver.sh file content #!/bin/sh ## 1.Create folder ROOTPATH=$(pwd)/orangepi-5plus mkdir -p ${ROOTPATH} & amp; & amp; cd ${ROOTPATH} ## 2. Download the cross-compilation tool wget https://mirrors.tuna.tsinghua.edu.cn/armbian-releases/_toolchain/gcc-arm-11.2-2022.02-x86_64-aarch64-none-linux-gnu.tar.xz […]

Allwinner Orangepi serial communication development

Developed using the wiringPi library: Copy: cp ../wiringpifromWindows/wiringOP-master/examples/serialTest.c .. Use the serial port assistant (Anxinke): connect the pins TX–RX, RX–TX, GND–ground Data interaction: Allwinner’s board calls the wiringpi library to transmit data through the serial port, and there is a problem of how to receive data always wrong, or the received data is incomplete: The […]
