13DOF Click

13DOF Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example displays values registered by sensors on Click board.

Example Libraries

• MikroSDK.Log
• Click.13DOF

Example Key Functions

• c13dof_cfg_setup Config Object Initialization function.

void c13dof_cfg_setup ( c13dof_cfg_t *cfg );

void c13dof_default_cfg ( c13dof_t *ctx );

• c13dof_bmi088_read_accel Function reads 16-bit X-axis, Y-axis data and Z-axis data.

void c13dof_bmi088_read_accel ( c13dof_t *ctx, int16_t *accel_x, int16_t *accel_y, int16_t *accel_z );

• c13dof_bmi088_accel_read_bytes Function read a sequential data starting from the targeted 8-bit register address.

err_t c13dof_bmi088_accel_read_bytes ( c13dof_t *ctx, uint8_t *data_out, uint8_t reg_address, uint8_t n_bytes );

• c13dof_bmi088_read_gyro Function reads 16-bit X-axis, Y-axis data and Z-axis data of BMM150 sensor on 13DOF Click board.

void c13dof_bmi088_read_gyro ( c13dof_t *ctx, int16_t *gyro_x, int16_t *gyro_y, int16_t *gyro_z );

Application Init

Initialization driver enables - BME680 Low power gas, pressure, temperature & humidity sensor, BMI088 6-axis Motion Tracking Sensor and BMM150 Geomagnetic Sensor, also write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c13dof_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    c13dof_cfg_setup( &cfg );
    C13DOF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c13dof_init( &c13dof, &cfg );
    c13dof_default_cfg( &c13dof );
}

Application Task

This is a example which demonstrates the use of 13DOF Click board. Measures and display temperature in degrees Celsius [ C ], humidity data [ % ], pressure [ mbar ] and gas resistance data from the BME680 sensor. Measures and display Accel and Gyro data coordinates values for X-axis, Y-axis and Z-axis from the BMI088 sensor. Measures and display Geomagnetic data coordinates values for X-axis, Y-axis and Z-axis from the BMM150 sensor. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for each second.

void application_task ( void )
{
    temperature = c13dof_bme680_get_temperature( &c13dof );

    log_printf( &logger, "----------------------------------------------------------\n");
    log_printf( &logger, "Temperature : %.2f C \r\n", temperature );

    humidity = c13dof_bme680_get_humidity( &c13dof );
    log_printf( &logger, "Humidity : %.2f %% \r\n", humidity );

    pressure = c13dof_bme680_get_pressure( &c13dof );
    log_printf( &logger, "Pressure : %.2f mbar \r\n", pressure );

    gas_res = c13dof_bme680_get_gas_resistance( &c13dof );
    log_printf( &logger, "Gas Resistance : %ld \r\n", gas_res );
    
    ready_check = c13dof_bmm150_check_ready( &c13dof );

    while ( ready_check != C13DOF_BMM150_DATA_READY )
    {
        ready_check = c13dof_bmm150_check_ready( &c13dof );
    }
    
    c13dof_bmi088_read_accel( &c13dof, &accel_x, &accel_y, &accel_z );
    c13dof_bmi088_read_gyro( &c13dof, &gyro_x, &gyro_y, &gyro_z );
    c13dof_bmm150_read_geo_mag_data( &c13dof, &mag_x, &mag_y, &mag_z, &r_hall );
    
    log_printf( &logger, "Accel X : %d ", accel_x );
    log_printf( &logger, " Y : %d ", accel_y );
    log_printf( &logger, " Z : %d \r\n", accel_z );
    
    log_printf( &logger, "Gyro X : %d ", gyro_x );
    log_printf( &logger, " Y : %d ", gyro_y );
    log_printf( &logger, " Z : %d \r\n", gyro_z );
        
    log_printf( &logger, "Mag X : %d ", mag_x );
    log_printf( &logger, " Y : %d ", mag_y );
    log_printf( &logger, " Z : %d \r\n", mag_z );

    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
