WebThe I2C protocol uses open drain pins. The pins can pull signal voltages low, but they cannot pull them high. The system relies on pull up resistors to do this. This library enables the … WebPull Up Resistors. The I2C protocol uses open drain pins to pull signal voltages low and pull up resistors to pull voltages back up again. This library enables the Teensy's 22 kΩ internal pull up resistor by default. Many sensors that support I2C often have internal pullups as well. These may provide enough resistance for your application.
