The previous article introduced the ARM DesignStart program, which mentioned the Cortex-M1/M3 DesignStart FPGA version, supporting Xilinx and domestic Gowin platforms. This article will guide you through how to build an Cortex-M3 soft core processor on FPGA based on the ARM DesignStart program, using the Xilinx Artix-7™ series FPGA as an example. It will cover how to customize an ARM Cortex-M3 SoC soft core, add GPIO and UART
With the development of industrial technology, the application field of HMI (Human-Machine Interface) is becoming increasingly broad. The custom communication protocol implemented by Topway's intelligent LCD display module can maintain the confidentiality of enterprise data to a certain extent, enhance the diversity of product functions, and solve the problem of incompatible communication protocols.
The serial communication rules for HMI, except for standard Modbus protocol products, are mostly based on the protocol rules set by the original manufacturer.
The Raspberry Pi can be used to create a system from scratch or to work with an existing system. Beginners will definitely start with an existing system. Later on, you can compile the kernel, debug the kernel, and build your own root filesystem. I will also introduce some basic commands, learning while using. Additionally, I will share some knowledge about Linux that I have learned. Please point out any mistakes.
To facilitate learning about the Raspberry Pi and Linux, and to
Editor's Note: This is an old article from several years ago that I came across today and found it to be quite insightful, so I would like to share it with everyone.
When it comes to domestic CPU products like Loongson, the biggest controversy surrounding it is its performance. Although the early products from Loongson did not satisfy everyone, with the disclosure of the new

Arduino is an open-source hardware platform that can be used to develop various interactive application devices. It is one of the commonly used platforms for technology learning, product prototyping, and maker activities. It is also one of the best platforms for cultivating maker spirit and hands-on abilities. The emergence of Arduino has greatly lowered the threshold for interactive design, allowing amateurs to create various

The first time I encountered the MVP design pattern was in 2014 when I read "Building High-Quality Android Applications: 50 Essential Tips for Android Development". Since then, I have gradually tried to use it, and so far, it is not a model that can be perfectly applied to every scenario; it
Today, I would like to introduce NVIDIA Jetson TX2 NX.
In a very warm working environment, the RTC clock occasionally experiences delays or timeouts. A mature RTC circuit design may seem simple, but how can we ensure the accuracy of the RTC clock? When occasional anomalies occur, how can we quickly locate and resolve the issues? This article will share a case study.
The industrial control board uses the NXP PCF8563 RTC chip solution. During the environmental temperature
