Timer Click

Timer Click is a mikroBUS add-on board with Maxim’s DS1682 total elapsed time recorder. The main feature of the IC is its elapsed time counter (ETC) used in conjunction with the ALARM pin.

Click library

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

Software Support

We provide a library for the Timer 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 Timer Click driver.

Standard key functions :

  • Config Object Initialization function.

    void timer_cfg_setup ( timer_cfg_t *cfg );

  • Initialization function.

    TIMER_RETVAL timer_init ( timer_t ctx, timer_cfg_t cfg );

Example key functions :

  • Get elapsed time counter (ETC) data function

    uint32_t timer_get_etc_data ( timer_t *ctx );

  • Get elapsed time counter (ETC) seconds function

    uint32_t timer_get_etc_seconds ( timer_t *ctx );

  • Set elapsed time counter (ETC) time function

    void timer_get_time ( timer_t ctx, uint16_t time_days, uint8_t time_hours, uint8_t time_minutes, uint8_t *time_seconds );

Examples Description

This application is multifunctional 3-axis digital accelerometer that can also be configured as a 45-degree Tilt sensor.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, soft reset, sets ETC and EC start ( seconds ), hardwere reset and > start write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    timer_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.

    timer_cfg_setup( &cfg );
    TIMER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    timer_init( &timer, &cfg );
    Delay_ms ( 200 );

    log_printf( &logger, "   Driver  Init   \r\n" );
    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "    Soft Reset    \r\n" );

    timer_soft_reset( &timer );
    Delay_ms ( 500 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "  Set ETC and EC  \r\n" );

    timer_set_etc_seconds( &timer, 86390 );
    timer_set_ec_seconds( &timer, 0 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "  Hardwere Reset  \r\n" );

    timer_hw_reset( &timer );
    Delay_ms ( 500 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "        ETC       \r\n" );
    log_printf( &logger, "------------------\r\n" );
}

Application Task

This is a example which demonstrates the use of Timer Click board. Timer Click communicates with register via I2C by write to register and read from register, display time ( days, hours, minutes and seconds ) which we
received reading from the target register address of DS1682 total > elapsed time recorder. Results are being sent to the Usart Terminal where you can track > their changes. All data logs write on usb uart changes for every 1 sec.


void application_task ( )
{
    static uint8_t time_seconds_new = 0xFF;
    uint8_t time_hours;
    uint8_t time_minutes;
    uint8_t time_seconds;
    uint16_t time_days;

    timer_get_time( &timer, &time_days, &time_hours, &time_minutes, &time_seconds );

    if ( time_seconds_new != time_seconds )
    {
        log_printf
        ( 
            &logger, " %d days    %d:%d:%d \r\n", 
            time_days, 
            time_hours, 
            time_minutes, 
            time_seconds
        );
        log_printf( &logger, "------------------\r\n" );
        time_seconds_new = time_seconds;
    }
    Delay_ms ( 1 );
}

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.Timer

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.
