Click library

  • Author : Stefan Ilic
  • Date : Aug 2023.
  • Type : I2C type

Software Support

We provide a library for the Temp Alarm 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Temp Alarm Click driver.

Standard key functions :

  • tempalarm_cfg_setup Config Object Initialization function.

    void tempalarm_cfg_setup ( tempalarm_cfg_t *cfg );
  • tempalarm_init Initialization function.

    err_t tempalarm_init ( tempalarm_t *ctx, tempalarm_cfg_t *cfg );
  • tempalarm_default_cfg Click Default Configuration function.

    err_t tempalarm_default_cfg ( tempalarm_t *ctx );

Example key functions :

  • tempalarm_write_reg Temp Alarm register writing function.

    err_t tempalarm_write_reg ( tempalarm_t *ctx, uint8_t reg, uint8_t data_in );
  • tempalarm_read_remote_temperature Temp Alarm remote sensor read temperature function.

    err_t tempalarm_read_remote_temperature ( tempalarm_t *ctx, float *temperature );
  • tempalarm_set_alarm_high_limit Temp Alarm remote sensor set limit high temperature function.

    err_t tempalarm_set_alarm_high_limit ( tempalarm_t *ctx, float max_temperature );

Example Description

This example demonstrates the use of Temp Alarm Click board by reading and displaying the temperature measurements and monitoring it.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the Local sensor critical temperature at 30 degC with hysteresis of 1 degC, and Remote sensor alarm temperature at 30 degC.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    tempalarm_cfg_t tempalarm_cfg;  /**< Click config object. */

    /** 
     * 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.
    tempalarm_cfg_setup( &tempalarm_cfg );
    TEMPALARM_MAP_MIKROBUS( tempalarm_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == tempalarm_init( &tempalarm, &tempalarm_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( TEMPALARM_ERROR == tempalarm_default_cfg ( &tempalarm ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART approximately once per second. Monitoring alarm and critical state.

void application_task ( void ) 
{
    uint8_t flag_data = 0; 
    int8_t local_temp = 0;
    float remote_temp = 0;
    tempalarm_get_alarms( &tempalarm, &flag_data );
    if ( TEMPALARM_ADC_BUSY_MASK != ( TEMPALARM_ADC_BUSY_MASK & flag_data ) )
    {
        tempalarm_read_temperature( &tempalarm, &local_temp );
        tempalarm_read_remote_temp( &tempalarm, &remote_temp );
        log_printf( &logger, " Local temperature : %d degC \r\n" , ( int16_t ) local_temp );
        log_printf( &logger, " Remote temperature : %.3f degC \r\n" , remote_temp );
        log_printf( &logger, " -------------------------------- \r\n" );
    }
    if ( TEMPALARM_PIN_STATE_LOW == tempalarm_get_alr_pin( &tempalarm ) )
    {
        log_printf( &logger, " Alarm is on, remote temperature  \r\n" );
        log_printf( &logger, "      is higher then 30 degC      \r\n" );
        log_printf( &logger, " -------------------------------- \r\n" );
    }
    if ( TEMPALARM_PIN_STATE_LOW == tempalarm_get_tcr_pin( &tempalarm ) )
    {
        log_printf( &logger, " Alarm is on, local temperature  \r\n" );
        log_printf( &logger, "      is higher then 30 degC      \r\n" );
        log_printf( &logger, " -------------------------------- \r\n" );
    }
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempAlarm

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. UART terminal is available in all MikroElektronika compilers.

Hall Current Click

0

Hall Current Click is a compact add-on board that contains a precise solution for AC/DC current sensing. This board features the TLI4970-D050T4, a 16-bit digital SPI output (13-bit current value) coreless magnetic current sensor designed for the current range of ±25A from Infineon Technology. A differential measurement principle allows effective stray field suppression with a highly linear output signal without hysteresis. Due to the integrated primary conductor (current rail), there is no need for external calibration. The TLI4970-D050T4 is highly accurate over temperature range and lifetime with fast overcurrent detection with a configurable threshold.
