Heater Click

Heater Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

The devices resolution depends on settings applied. User should consult the datasheet and choose resolution value that corresponds to the settings applied.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Heater

Example Key Functions

• heater_cfg_setup Config Object Initialization function.

void heater_cfg_setup ( heater_cfg_t *cfg );

• heater_init Initialization function.

err_t heater_init ( heater_t *ctx, heater_cfg_t *cfg );

• heater_default_cfg Click Default Configuration function.

void heater_default_cfg ( heater_t *ctx );

• heater_read_data This function writes data to the desired register.

uint16_t heater_read_data ( heater_t *ctx );

• heater_read_mv Read data in mV.

float heater_read_mv (  heater_t *ctx  );

• heater_read_temp Read data in C.

float heater_read_temp (  heater_t *ctx  );

Application Init

Initialization of PWM module and start heating up

void application_init ( void )
{
    log_cfg_t log_cfg;
    heater_cfg_t cfg;
    heater_config_t cfg1;

    /** 
     * 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 ----\r\n" );

    //  Click initialization.

    heater_cfg_setup( &cfg, &cfg1 );
    HEATER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    heater_init( &heater, &cfg, &cfg1 );
    
    frequency = 500;
    
    heater_set_duty_cycle( &heater, heater.pwm_period );
    status_dev = HEATER_HEATING;
    
    log_printf( &logger, " ***** APP INIT ***** \r\n" );
    Delay_ms ( 500 );

}

Application Task

Durning the task device is heating up to 50 degree C and then cooling down to 40 degree C

void application_task ( void )
{
    temp_read = heater_read_temp( &heater );
    
    if ( ( temp_read > HOT_TEMP ) && ( status_dev == HEATER_WAITING ) )
    {
    status_dev = HEATER_COOLING;
    }
    else if ( ( temp_read < COOL_TEMP ) && ( status_dev == HEATER_WAITING ) )
    {
    status_dev = HEATER_HEATING;
    }

    if ( status_dev == HEATER_HEATING )
    {
    heater_pwm_start ( &heater );
    heater_set_led1_status( &heater, HEATER_LED_ON );
    heater_set_led2_status( &heater, HEATER_LED_OFF );
    status_dev = HEATER_WAITING;
    }
    else if ( status_dev == HEATER_COOLING )
    {
    heater_pwm_stop ( &heater );
    heater_set_led1_status( &heater,HEATER_LED_OFF );
    heater_set_led2_status( &heater,HEATER_LED_ON );
    status_dev = HEATER_WAITING;
    }

    log_printf( &logger,  " - Temperature: %.2f %s\r\n", temp_read, log_degree );
    
    log_printf( &logger, "***************\r\n" );

    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
