Or perhaps your microcontroller has two I2C ports and of course defaults to the one that you aren't using. If the pin is connected to GND the SAD[0] bit is 0, if the pin is connected to VDD_IO the SAD[0] bit is 1. Specify the I2C address of the sensors when multiple I2C devices with the expected address for LSM9DS1 are connected to the same hardware board. settings. You'll need to move the SparkFun_LSM9DS1_Arduino_Library folder into a libraries folder within your Arduino sketchbook. // Use either IMU_MODE_I2C or IMU_MODE_SPI imuA. :param ~busio.

In I2C mode, this selects the LSb of the I2C Feb 1, 2017 · Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. However, it seems all the LSM9DS1 boards in my possession have the same I2C address. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. I'm just starting out learning about this stuff and I am having troubles reading from the sensor. 3V, ground, and the I2C clock (SCL) and I2C data (SDA) pins from the hat. LSM9DS1 can have multiples peripheral addresses which depends on the logic level on pins SDO_A/G and SDO_M of the sensor. 1 , I'm double-checking the LSM9DS1 C drivers on Github from ST, which are working: /** @defgroup LSM9DS1_Infos * @{ * */ /** I2C Device Address 8 bit format if SA0=0 -> 0xD5 if SA0=1 -> 0xD7 **/ #define LSM9DS1_IMU_I2C_ADD_L 0xD5U #define LSM9DS1_IMU_I2C_ADD_H 0xD7U /** I2C Device Address 8 bit format if SA0=0 -> 0x3D if SA0=1 -> 0x39 **/ #define LSM9DS1_MAG_I2C_ADD_L 0x3DU #define Specify the I2C address of the sensors when multiple I2C devices with the expected address for LSM9DS1 are connected to the same hardware board. commInterface = IMU_MODE_I2C; // [mAddress] sets the I2C address or SPI CS pin of the Apr 18, 2023 · Change the address either in your code, or jumper the address pin on the BNO085 breakout. accel/gryo and mag I2C addresses: JP1 pulls the SDA and SCL data lines high through R1 and R2. SPI serial data output (SDO) for the magnetometer.
