I2C Bus speed (Hz)

Rate at which data is transferred over I2C bus

Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / I2C properties

Description

Set the rate at which data is transferred over the I2C bus in Hertz. This speed determines the data communication rate between peripherals that are connected by the I2C bus.

Settings

100000

For every I2C module, you can individually configure the bus speed, SDA and SCL pins. However, not all Arduino^® boards support configuring I2C module 0 and module 1. This table lists the I2C modules supported by different Arduino boards.
