Bit-bang interface

WebSep 1, 2024 · The SPI interface can be either three or four wires. One significant advantage of it is that data can be transmitted without interruption. In a continuous stream, any number of bits may be sent or received. Data is sent in packets with I2C and UART, each of which is limited to a certain number of bits. In computer engineering and electrical engineering, bit banging is a "term of art" for any method of data transmission that employs software as a substitute for dedicated hardware to generate transmitted signals or process received signals. Software directly sets and samples the states of GPIOs (e.g., pins on a microcontroller), and is responsible for meeting all timing requirements and protocol sequencing of the signals. In contrast to bit banging, dedicated hardware (e.g., UART, SPI
