Overview of RS232 The RS-232 interface complies with the serial data communication interface standard established by the Electronic Industries Alliance (EIA). The original designation is EIA-RS-232 (abbreviated as 232, RS232). It is widely used for connecting computer serial interface peripherals. This includes connection cables as well as mechanical, electrical, signal, and transmission processes. The RS-232-C … Read more
The RS-485 interface forms a half-duplex network, typically using a two-wire system with shielded twisted pair transmission. This wiring method allows for a bus topology structure, enabling up to 32 nodes to be connected on the same bus. Initially, data was output as analog signals for simple process quantities, and later, the RS-232 interface was … Read more
The I2C bus is one of the most commonly used communication protocols in embedded systems, serving as a “dedicated highway” between microcontrollers and various sensors and memory devices. Today, let’s discuss how this protocol works and how to use it to read data from temperature and humidity sensors. I2C Protocol Basics The I2C protocol uses … Read more
