1 FINSH ConsoleWith the console, we can reduce trial and error costs when debugging hardware, change PID parameters in real-time without needing to reprogram, and customize commands to call serial API for testing communication protocols. This article summarizes the entire porting process.2 Preparation Before Porting2.1 Testing EnvironmentThis test is an extension based on the io_toggle … Read more
The previous article organized common communication interfaces I (RS232/RS485/USB/TYPE-C principles and differences), and in this article, we continue to organize the principles and differences of CAN, I2C, SPI, UART, and GPIO. 1.CAN Bus Interface 1)Definition CAN stands for Controller Area Network, developed by the German company BOSCH, known for its research and production of automotive … Read more
Applications of C Language in Embedded Systems: Hardware Interface Programming Introduction The C language is a widely used programming language, especially significant in embedded system development.

Original Author: STM32 Chinese Community User Sanjie Dog This is the third review post for the NUCLEO_L552ZE_Q development board. The previous post introduced how to set up the development environment on the Windows platform. Now that the environment is ready, we can start writing programs for testing (I won’t be writing programs myself, as I … Read more
This is the 169th content shared by the platform. GPIO (General Purpose Input/Output) is a versatile interface used to connect microcontrollers, embedded systems, or other electronic devices to interact with the external world.GPIO is a highly flexible interface that can perform various functions such as digital input, digital output, analog input, and analog output. In … Read more
C++ Embedded Development: Hardware Interfaces and Real-Time Programming In today’s rapidly evolving technological environment, embedded systems have become a core component of many electronic products. C++, as a powerful programming language, is increasingly favored in the field of embedded development due to its object-oriented features. In this article, we will explore how to use C++ … Read more
This article will cover the following topics: Introduction to F1C100s, U-Boot, Linux kernel customization, and application development using C or C++. We will also provide two examples: a simple example controlling an LED blinking and another creating a GUI program with a button. F1C100s Performance Parameters The F1C100s is a low-cost, low-power 32-bit processor commonly … Read more
Requirement Description For scenarios that require extremely high real-time response (such as power failure detection), interrupts must be used. However, for the imx6ulx, which is a Linux platform, there are no convenient interrupt operations like those in RTOS. To achieve the same smooth operation, both the kernel driver and the application layer program need to … Read more
The GPIO port connects to the BEEP pin of terminal J2, allowing the buzzer to sound by inputting a high level on the GPIO port. Frequency: Pitch, kHz Duty Cycle: Sound intensity, 0~100% The duty cycle is the ratio of the time the high level is on to the signal period: Duty Cycle = (Time … Read more
