Click library

  • Author : MikroE Team
  • Date : jul 2020.
  • Type : I2C type

Software Support

We provide a library for the Force4 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 Force4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void force4_cfg_setup ( force4_cfg_t *cfg );

  • Initialization function.

    FORCE4_RETVAL force4_init ( force4_t ctx, force4_cfg_t cfg );

Example key functions :

  • This function reads 12bit ADC data from device.

    uint16_t force4_read_adc ( force4_t *ctx )

Examples Description

This example shows the use of Force 4 Click. It reads 12bit ADC value, using I2C communication, at the interval of one second. The result is represented on the UART terminal.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger, and makes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    force4_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 );
    Delay_ms ( 100 );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    force4_cfg_setup( &cfg );
    FORCE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    force4_init( &force4, &cfg );
    Delay_ms ( 100 );
}

Application Task

It reads 12bit ADC value, using I2C communication, at the interval of one second. The result is represented on the UART terminal.


void application_task ( void )
{
    adc_val = force4_read_adc( &force4 );
    log_printf( &logger, "ADC value: %d\r\n", adc_val );
    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.Force4

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.
