WebbSometimes the bus is called IIC or I²C bus. The original communication speed was defined with a maximum of 100 kbit per second and many applications don’t require faster transmissions. For those that do there is a 400 kbit fastmode and – since 1998 – a high speed 3.4 Mbit option available. Webb22 jan. 2024 · I2C is made up of two signals: a clock (SCL), and a data line (SDA). By default, the lines are pulled high by resistors. To communicate, a device pulls lines low and releases them to let them rise back to high. Ones and Zeroes As a digital bus, I2C ultimately transmits 1s and 0s between two circuits.

Webb9 juli 2024 · Answer. The clock of the I2C bus is composed of four regions: Low time. Rise time. High time. Fall time. Because the I2C module uses pins in open-drain mode, the fall time is relatively negligible, since the drivers will be pulling low reasonably quickly. The other three times compose the overall clock speed. WebbThe I2C bus consists of two lines: serial data line (SDA) and serial clock (SCL). Both lines require pull-up resistors.
