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
Introduction Why Should We Understand Both Hardware and Software? In 2010, while I was at Huawei, I temporarily took a break from my regular duties to participate in recruitment efforts. To recruit more people for my department and compete for HC numbers (the number of positions available), I worked hard to ensure that every candidate … Read more
The following is an example program that simulates an SPI (Serial Peripheral Interface) bus controller using the C language, implementing the functionality of SPI through simulated GPIO pin operations, including initialization, sending bytes, and receiving bytes. This example is suitable for general microcontroller platforms, and the GPIO operation code needs to be modified according to … Read more
Applications of C Language in Embedded Systems 1. Introduction In modern technology, embedded systems are ubiquitous, ranging from household appliances to industrial automation devices. These systems often have limited computational resources, making the choice of programming language crucial. The C language, due to its efficiency, portability, and direct control over hardware, is particularly well-suited for … Read more
