Webb13 feb. 2016 · I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line). Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. The clock signal is always controlled by the master. pay federal withholding tax onlineWebb4 apr. 2024 · I2C Register is a python library which aims to make communicating with registers on I2C devices dead simple.
