Originally, I planned to do something big over the weekend, like WIFI and web pages. However, after two days of work and discussions with foreign friends, I realized that there was a problem with the firmware. After communicating with a senior expert at night, I found out that the official firmware for the ESP32S has … Read more
RPPAL is a powerful library that provides a user-friendly interface for Raspberry Pi, allowing you to easily access peripherals such as GPIO, I2C, PWM, SPI, and UART. It not only enables you to control these peripherals effortlessly but also supports USB-to-serial adapters, allowing for more interesting development on the Raspberry Pi. The Core Advantages of … Read more
In the world of electronics, lighting up an LED is often the first task for those learning Arduino or other microcontrollers, similar to the “Hello World” in C programming. This time, we will also try to light up an LED using the GPIO of the Raspberry Pi. 1. Understanding the GPIO of Raspberry Pi B … Read more
Chapter 1: Basics of RPi.GPIO Module Importing the Module To import the RPi.GPIO module: import RPi.GPIO as GPIO By doing this, you can refer to it as GPIO for the rest of this script. You can check if the module was imported successfully by throwing an exception: try: import RPi.GPIO as GPIO except RuntimeError: print("Error … Read more
The previous LED light used the output function of GPIO, and this time we finally need to use the input function of GPIO. Since the use of this human infrared sensing module is relatively simple, we will create a simple human sensing alarm system in conjunction with the previous buzzer after the experiment is complete. … Read more
Course OK01 explains how to get started with the Raspberry Pi and how to enable the OK or ACT LED indicators near the RCA and USB ports. This indicator was initially designed to indicate the OK status but was renamed ACT in the second version of the Raspberry Pi. — Robert Mullins Acknowledgments Translated from … Read more
1. Overview Many friends have already started playing with Arduino, and they usually use the official Arduino IDE to write programs to control Arduino hardware. To make control more convenient, Microsoft launched Windows Remote Arduino in the Windows IoT program. In simple terms, Windows Remote Arduino is an open-source Windows runtime component that allows us … Read more
1、GPIO Structure and Registers GPIO includes multiple 16-bit I/O ports, each of which can independently set 3 types of input modes and 4 types of output modes, and can be independently set or reset. GPIO consists of registers, input drivers, output drivers, and other components, as shown in the figure below. GPIO operates through 7 … Read more
