Click on the aboveblue text to follow us MCU debuggers play an important role in embedded development. The price difference is usually determined by multiple factors such as functionality, compatibility, performance, and support services. 1 Basic Functionality and Protocol Support for SWD The two-wire debugging protocol (SWDIO and SWCLK) commonly used for ARM Cortex-M series … Read more

With the rapid development of electronic technology, microcontrollers are increasingly used in various electronic systems. Initially, there were not many issues in simple systems, but in complex systems, multiple microcontrollers need to work together to achieve their respective functions and communicate with each other. Therefore, learning how to choose the communication method for microcontrollers is … Read more

1 UART UART is an asynchronous serial communication protocol, with the full English name Universal Asynchronous Receiver/Transmitter. Unlike communication protocols such as SPI and I2C, it is also a commonly used IP in SoCs. Its greatest advantage is that it uses only two wires for communication, supporting full-duplex, meaning one wire (UTx) is used for … Read more
Buses, buses, they always get you tangled up. In this world, signals may be the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses are used for interconnections between peripheral chips and processors within … Read more
