Thermo 9 Click

Thermo 9 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 : Jovan Stajkovic
• Date : Jan 2020.
• Type : I2C/SPI type

Software Support

Example Description

This demoapp measures temperature every 3 seconds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Thermo9

Example Key Functions

• thermo9_cfg_setup Config Object Initialization function.

void thermo9_cfg_setup ( thermo9_cfg_t *cfg );

• thermo9_init Initialization function.

err_t thermo9_init ( thermo9_t *ctx, thermo9_cfg_t *cfg );

• thermo9_send_cmd Function is used to send the command to the device.

void thermo9_send_cmd ( thermo9_t *ctx, uint8_t cmd_byte );

• thermo9_calibation Function resets and calibrates the device in order for it to work properly.

void thermo9_calibation ( thermo9_t *ctx );

• thermo9_read_temp Function is used to read temperature in degree centigrade.

float thermo9_read_temp ( thermo9_t *ctx );

Application Init

Logger initialization, Click initialization and calibration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo9_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_printf( &logger, "---- Application Init ----\r\n" );

    //  Click initialization.

    thermo9_cfg_setup( &cfg );
    THERMO9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo9_init( &thermo9, &cfg );
    Delay_ms ( 100 );
    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "    Thermo 9 Click   \r\n" );
    log_printf( &logger, "---------------------\r\n" );
    thermo9_calibation( &thermo9 );
    Delay_ms ( 100 );
    log_printf( &logger, "      Calibrated     \r\n" );
    log_printf( &logger, "---------------------\r\n" );
}

Application Task

This example shows capabilities of Thermo 9 Click by measuring temperature every 3 seconds and displaying temperature in degrres Celsius via USART terminal.

void application_task ( void )
{
    //  Task implementation.
    temp_val = thermo9_read_temp( &thermo9 );
    log_printf( &logger, "-- Temperature : %.2f °C\r\n", temp_val );

    log_printf( &logger, "-----------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

Calibration function must be used once in order to get calibrations!

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.
