Embedded Programming in ALGOL: Hardware Interfaces and Real-Time Systems Introduction ALGOL (Algorithmic Language) is a historic programming language that, although less popular today compared to languages like C and Python, played a significant role in the development of computer science. This article will introduce how to use ALGOL for embedded programming, particularly in the application … Read more
As we all know, the engine speedometer in a car dashboard can monitor and display the engine speed in real-time, such as 1200 revolutions per minute. If we perform open-source hardware programming with a Raspberry Pi, utilizing a Hall sensor to detect magnetic fields and count the number of rotations, we can ultimately develop a … Read more
It is believed that the first task for anyone learning Arduino or other microcontrollers is to light up an LED, similar to the ‘Hello World’ program in C language. This time, we will also try to light up an LED using the GPIO of the Raspberry Pi. 1. Understanding Raspberry Pi B’s GPIO GPIO (General-purpose … Read more
In previous sections, we used the GPIO output function for the LED lights. This time, we will finally need to use the GPIO input function. The human infrared sensing module is quite simple to use. After completing our experiment, we will combine it with the previous buzzer to create a simple human detection alarm. 1. … Read more

Introduction In the previous article, we briefly introduced the difference between bare-metal drivers and device drivers, as well as the driver architecture of character devices in the Linux kernel. Without an operating system, upper-layer applications directly access the driver interface, and application engineers need to know the driver interface for each device. When accessing Flash, … Read more
Click on the above“Mechanical and Electronic Engineering Technology” to follow us The ultrasonic sensor is an electronic sensor based on acoustic principles. It measures the distance between the sensor and an object by emitting ultrasonic pulses and receiving reflected signals, and is used to detect the presence of objects. It has widespread applications in modern … Read more

Previously, it was explained that when external registers need to be added, the bus interconnection module must be changed. In the bus interconnection module, each register has a wire connected to the bus interconnection module for reading data and enabling signals. If there are relatively few registers, it seems there is no problem. But what … Read more
