The RS-232 interface complies with the standards for serial data communication set by the American Electronics Industry Association (EIA), with the original full designation being EIA-RS-232 (abbreviated as 232, RS232). It is widely used for connecting peripherals to computers via serial interfaces. The connection cables and the mechanical, electrical characteristics, signal functions, and transmission processes … Read more

Question: >>> How to connect the analog world to the physical world? Engineers will readily provide the answer—use ADC and DAC. Analog-to-digital converters (ADC) and digital-to-analog converters (DAC) are devices that convert analog signals into digital signals or vice versa. In this area, ADI offers a comprehensive range of data converter products, with DACs covering … Read more
The CAN bus terminal resistor, as the name suggests, is the resistor added at the end of the bus. Although small, this resistor plays a very important role in CAN bus communication. The Role of Terminal Resistors There are two main roles of the CAN bus terminal resistor: 1. Improve anti-interference capability, ensuring the bus … Read more
Communication between electronic devices is like communication between humans; both parties need to speak the same language. In electronic products, these languages are called communication protocols. Previously, articles on SPI, UART, and I2C communication were shared separately. This article compares them. Serial vs Parallel Electronic devices communicate by sending data bits to each other. A … Read more
