Click library

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

Software Support

We provide a library for the Accel8 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 Accel8 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void accel8_cfg_setup ( accel8_cfg_t *cfg );

  • Initialization function.

    ACCEL8_RETVAL accel8_init ( accel8_t ctx, accel8_cfg_t cfg );

  • Click Default Configuration function.

    void accel8_default_cfg ( accel8_t *ctx );

Example key functions :

  • This function reads Accel axis data.

    void accel8_get_accel_axis ( accel8_t ctx, int16_t x_axis, int16_t y_axis, int16_t z_axis );

  • This function reads Gyro axis data.

    void accel8_get_gyro_axis ( accel8_t ctx, int16_t x_axis, int16_t y_axis, int16_t z_axis );

  • This function returns Interupt state.

    uint8_t accel8_get_interrupt ( accel8_t *ctx );

Examples Description

This application measures accelermeter and gyroscopic data and temperature.

The demo application is composed of two sections :

Application Init

Initialization driver init, reset chip and start configuration chip for measurement.


void application_init ( void )
{
    log_cfg_t log_cfg;
    accel8_cfg_t cfg;

    uint8_t temp_write;

    /** 
     * 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.

    accel8_cfg_setup( &cfg );
    ACCEL8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel8_init( &accel8, &cfg );

    log_printf( &logger, " *-* Device Reset *-* \r\n");
    temp_write = ACCEL8_PM1_DEVICE_RESET;
    accel8_generic_write( &accel8, ACCEL8_REG_PWR_MGMT_1, &temp_write, 1 );
    temp_write = ACCEL8_GYRO_RESET | ACCEL8_ACCEL_RESET | ACCEL8_TEMP_RESET;
    accel8_generic_write( &accel8, ACCEL8_REG_SIGNAL_PATH_RESET, &temp_write, 1 );

    log_printf( &logger, " *-* Device Configuration *-* \r\n" );
    accel8_default_cfg ( &accel8, ACCEL8_INTE_DATA_RDY_ENABLE, ACCEL8_GYRO_CFG_FULL_SCALE_RANGE_250dbs, &range);

    Delay_ms ( 1000 );
    log_printf( &logger, " --- Start Measurement --- \r\n" );
}

Application Task

Reads Accel X/Y/Z axis, Gyro X/Y/Z axis and device Temperature. All data logs on the USBUART every 2 sec.


void application_task ( void )
{   
    float temperature;
    int16_t x_gyro_axis;
    int16_t y_gyro_axis;
    int16_t z_gyro_axis;
    int16_t x_accel_axis;
    int16_t y_accel_axis;
    int16_t z_accel_axis;

    //  Task implementation.

    accel8_get_accel_axis( &accel8,&x_accel_axis, &y_accel_axis, &z_accel_axis );
    accel8_get_gyro_axis( &accel8, &x_gyro_axis, &y_gyro_axis, &z_gyro_axis );
    temperature = accel8_get_temperature( &accel8 );

    // LOGS DATA

    log_printf( &logger, "________________ Accel 8 Click _________________\r\n" );
    log_printf( &logger, "|  Data   | X axis | Y axis | Z axis |  Range  |\r\n" );
    log_printf( &logger, "|_________|________|________|________|_________|\r\n" );
    log_printf( &logger, "|  Accel  | %d  | %d  | %d  | %dg |\r\n", x_accel_axis, y_accel_axis, z_accel_axis, accel_range );
    log_printf( &logger, "|_________|________|________|________|_________|\r\n" );
    log_printf( &logger, "|  Gyro   | %d  | %d  | %d  | %ddps|\r\n", x_gyro_axis, y_gyro_axis, z_gyro_axis, gyro_range );
    log_printf( &logger, "|_________|________|________|________|_________|\r\n" );
    log_printf( &logger, "|  Temp   | %.2f  C         |\r\n" , temperature);
    log_printf( &logger, "|_________|_________________|\r\n" );

    log_printf( &logger, " \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.Accel8

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.

Fuse Click is a compact add-on board that contains a programmable electronic power breaker. This board features the STPW12, an integrated electronic power breaker optimized to monitor the input power from STMicroelectronics. Connected in series to the power rail, it can disconnect the electronic circuitry on its output if the power consumption overcomes the programmed limit. The intervention of the protection is communicated to the MCU through a signal on the fault pin. The device can also be enabled/disabled through a dedicated Enable pin with a direct PWM mode, which can be achieved through an external PWM signal.
