Smart DOF 2 click

Smart DOF 2 Click is a compact add-on board with a highly advanced integrated 6-axis IMU measurement unit. This board features the LSM6DSV16XTR, a high-performance 6-axis IMU with sensor fusion, ASC, MLC, Qvar, and OIS/EIS paths from STMicroelectronics. The IMU unit features an accelerometer and gyroscope that can be turned off independently of each other, still allowed to have different ODRs and power modes. The unit can be configured as a finite state machine (FSM), machine learning core (MLC), and Qvar sensing.

Click library

  • Author : Nenad Filipovic
  • Date : Mar 2023.
  • Type : I2C/SPI type

Software Support

We provide a library for the Smart DOF 2 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Smart DOF 2 Click driver.

Example Description

This library contains API for Smart DOF 2 Click driver. The library initializes and defines the I2C or SPI bus drivers to write and read data from registers. The library also includes a function for reading accelerometer and gyroscope X-axis, Y-axis, and Z-axis data and the temperature in degrees Celsius.

The demo application is composed of two sections :

Application Init

The initialization of I2C or SPI module, log UART, and additional pins. After the driver init, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
smartdof2_cfg_t smartdof2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
smartdof2_cfg_setup( &smartdof2_cfg );
SMARTDOF2_MAP_MIKROBUS( smartdof2_cfg, MIKROBUS_1 );
err_t init_flag = smartdof2_init( &smartdof2, &smartdof2_cfg );
if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( SMARTDOF2_ERROR == smartdof2_default_cfg ( &smartdof2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, "--------------------------------------\r\n" );
}

Application Task

This example demonstrates the use of the Smart DOF 2 Click boardâ„¢. Measures and displays acceleration and gyroscope data for X-axis, Y-axis, and Z-axis. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
static smartdof2_axis_t acc_axis, gyro_axis;
if ( SMARTDOF2_OK == smartdof2_get_acc_axis( &smartdof2, &acc_axis ) )
{
if ( SMARTDOF2_OK == smartdof2_get_gyro_axis( &smartdof2, &gyro_axis ) )
{
log_printf( &logger, " Accel X: %.2f mg | Gyro X: %.2f mdps\r\n", acc_axis.x, gyro_axis.x );
log_printf( &logger, " Accel Y: %.2f mg | Gyro Y: %.2f mdps\r\n", acc_axis.y, gyro_axis.y );
log_printf( &logger, " Accel Z: %.2f mg | Gyro Z: %.2f mdps\r\n", acc_axis.z, gyro_axis.z );
log_printf( &logger, "--------------------------------------\r\n" );
}
}
Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.SmartDOF2

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
