Understanding UART, I2C, SPI, TTL, RS232, RS422, RS485, CAN, USB, SD Card, 1-WIRE, and Ethernet in Embedded Development
In microcontroller development, interfaces such as UART, I2C, and RS485 are commonly used, and understanding them can be somewhat ambiguous. This article organizes these concepts. The reading time is approximately 10 minutes. Universal Asynchronous Receiver-Transmitter (UART) The UART port refers to a type of physical interface (hardware). UART is an asynchronous, full-duplex serial bus. It … Read more
