WebThe SDO pin determines the I2C address of the module. This pin has a built-in pull-up resistor. Therefore, when you leave the SDO pin unconnected, the default I2C address is 0x77 Hex and when you connect it to GND, the line is pulled LOW and the I2C address becomes 0x76 Hex. SPI Interface. The sensor can also communicate via the SPI interface. 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.
