To build a stable and reliable Profibus-DP network, termination resistors can be considered a “small component with a big role”! Many engineers often overlook their importance, resulting in spending several days troubleshooting inexplicable communication failures, only to find out that it was the termination resistors causing the trouble. Today, we will analyze this seemingly simple … Read more
In a Profibus-DP network, the bus length is one of the key factors affecting system stability. As the bus length increases, signal attenuation, delay, and interference also increase, which changes the requirements for termination resistors. Today, we will discuss in detail how to correctly choose and install termination resistors for different lengths of Profibus-DP buses. … 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
