WebFor I2C, if all the slave devices have different device addresses, all of the SDA pins should be connected together, and all of the SCL pins should be connected together. It's as simple as that. Naturally, you should also … 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.

A 10K pull-up resistor on the module pulls this pin HIGH and so the I2C bus is selected by default unless this pin is grounded. The module supports two different I2C addresses, either 0x76 or 0x77 which allows up to 2 sensors to be used on the same … great crowned pigeongreat crowns and smilesWebThe 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. great crusade battlefield tours
