Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the GmrAngle 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 GmrAngle Click driver.

Standard key functions :

  • gmrangle_cfg_setup Config Object Initialization function.

    void gmrangle_cfg_setup ( gmrangle_cfg_t *cfg ); 
  • gmrangle_init Initialization function.

    err_t gmrangle_init ( gmrangle_t *ctx, gmrangle_cfg_t *cfg );

Example key functions :

  • gmrangle_read_data Generic read 16-bit data function.

    uint16_t gmrangle_read_data ( gmrangle_t *ctx, uint8_t reg );
  • gmrangle_write_data Generic write 16-bit data function.

    void gmrangle_write_data ( gmrangle_t *ctx, uint8_t reg, uint16_t tx_data );
  • gmrangle_calculate_angle Calculate angle function.

    float gmrangle_calculate_angle ( gmrangle_t *ctx );

Examples Description

This is an example which demonstrates the use of GMR Angle Click board.

The demo application is composed of two sections :

Application Init

Initializes GPIO pins, SPI and LOG modules.


void application_init ( void )
{
    log_cfg_t log_cfg;
    gmrangle_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.
    gmrangle_cfg_setup( &cfg );
    GMRANGLE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    gmrangle_init( &gmrangle, &cfg );

    GMRANGLE_SET_DATA_SAMPLE_EDGE; 

    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "   GMR Angle Click\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "        Start\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

Display angle value in degrees. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 300 msec.


void application_task ( void )
{
    angle = gmrangle_calculate_angle( &gmrangle );
    log_printf( &logger, " Angle is %.1f\r\n", angle );
    Delay_ms ( 300 );
} 

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.GmrAngle

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.

Altitude 6 Click

0

Altitude 6 Click is a compact add-on board that allows height measurement of an object or point related to sea level or ground level. This board features the MS5611-01BA03, a high-resolution barometric pressure sensor optimized for altimeter applications with an altitude resolution of 10 cm from TE Connectivity. It consists of a high linearity pressure sensor and an ultra-low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. Also, it provides a precise digital 24-bit pressure and temperature value, different operation modes, and a configurable host interface that supports both SPI and I2C serial communication allowing the user to optimize for conversion speed and current consumption. The high accuracy and stability of both pressure and temperature signal of the MS5611-01BA03 make this Click board™ suitable for height sensing in medical and consumer applications, indoor navigation, mobile altimeter or barometer systems, and many more.
