10DOF click

10DOF click is a mikroBUS add-on board for enhancing hardware prototypes with 10DOF functionality (10 degrees of freedom). The click board carries two modules from Bosch: BNO055, a 9-axis absolute orientation sensor and BMP180, a digital pressure sensor.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

We provide a library for the C10Dof 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for C10Dof Click driver.

Standard key functions :

• Config Object Initialization function.

void c10dof_cfg_setup ( c10dof_cfg_t *cfg );

• Initialization function.

C10DOF_RETVAL c10dof_init ( c10dof_t *ctx, c10dof_cfg_t *cfg );

• Click Default Configuration function.

void c10dof_default_cfg ( c10dof_t *ctx );

Example key functions :

• This function writes data to the desired register.

void c10dof_write_byte( c10dof_t *ctx, uint8_t reg, uint8_t data_in, uint8_t slave_addr );

• This function reads the ID value od the BMP180 chip.

uint8_t c10dof_bmp180_chip_ID ( c10dof_t *ctx );

• This function sets default configuration for the BMP180 sensor function.

void c10dof_default_configuration_BMP180 ( c10dof_t *ctx );

Examples Description

This is a example which demonstrates the use of 10DOF Click board. It measures temperature, humidity and pressure data from the BME180 chip sensor and accel, gyro and magnetometar coordinates values for X-axis, Y-axis and Z-axis.

The demo application is composed of two sections :

Application Init

Initialize the driver and sets the default configuration of BMP180 and BNO055 chip.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c10dof_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.

    c10dof_cfg_setup( &cfg );
    C10DOF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c10dof_init( &c10dof, &cfg );
    c10dof_default_cfg( &c10dof );
}
  

Application Task

Displays temperature, humidity and pressure data from the BMP180 and BNO055 sensors.

void application_task ( void )
{
    c10dof_read_accel( &c10dof, &accelX, &accelY, &accelZ );
    Delay_ms ( 10 );
    c10dof_read_gyro( &c10dof, &gyroX,  &gyroY, &gyroZ );
    Delay_ms ( 10 );
    c10dof_read_mag( &c10dof, &magX,  &magY, &magZ );
    Delay_ms ( 10 );
    
    temperature = c10dof_get_temperature( &c10dof );
    Delay_ms ( 10 );
    c10dof_get_measurements( &c10dof, &temperature, &pressure );
    Delay_ms ( 10 );

    log_printf( &logger, "Accel X : %d  |  ", accelX );
    log_printf( &logger, "Gyro X  : %d  |  ", gyroX );
    log_printf( &logger, "Mag X   : %d  |  ", magX );
    log_printf( &logger, "Temp.   : %.2f C  \r\n", temperature, deg_cel);

    log_printf( &logger, "Accel Y : %d  |  ", accelY);
    log_printf( &logger, "Gyro Y  : %d  |  ", gyroY);
    log_printf( &logger, "Mag Y   : %d  |  \r\n", magY);

    log_printf( &logger, "Accel Z : %d  |  ", accelZ);
    log_printf( &logger, "Gyro Z  : %d  |  ", gyroZ);
    log_printf( &logger, "Mag Z   : %d  |  ", magZ);
    log_printf( &logger, "Press.  : %.2f mbar \r\n", pressure);

    log_printf( &logger, "--------------------------------------------------------------------\r\n", pressure);
    Delay_ms ( 500 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.10Dof

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
