LSM6DSL click

LSM6DSL click measures linear and angular velocity with six degrees of freedom. It carries the LSM6DSL high-performance 3-axis digital accelerometer and 3-axis digital gyroscope. The click is designed to run on a 3.3V power supply. LSM6DSL click communicates with the target microcontroller over SPI or I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.

Mode 1: I2C slave interface or SPI serial interface is available.

Mode 2: I2C slave interface, or SPI serial interface and I2C interface master for external sensor connections, are available.

LSM6DSL inertial module features

The LSM6DSL is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 0.65 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience.

The event-detection interrupts enable efficient and reliable motion tracking and contextual awareness, implementing hardware recognition of free-fall events, 6D orientation, click and double-click sensing, activity or inactivity, and wakeup events

The LSM6DSL has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±245/±500/±1000/±2000 dps (degrees per second).

Code snippet

The following code snippet initializes the module, the driver, and peripherals, and then outputs the measured data to UART every two seconds.

01 void main()

03     char txt [100];
04     float x,y,z;

11      * Starts measurements for acceleration and rotation at specified
12      * rate (104 HZ) and selected full-scale (+-2G, +-245DPS).
