Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Thermo 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 Thermo Click driver.

Standard key functions :

  • Config Object Initialization function.

    void thermo_cfg_setup ( thermo_cfg_t *cfg );

  • Initialization function.

    THERMO_RETVAL thermo_init ( thermo_t ctx, thermo_cfg_t cfg );

Example key functions :

  • Function gets thermocouple temperature data.

    float thermo_get_temperature ( thermo_t* ctx );

  • Function checks fault states of MAX31855 sensor on Thermo Click board.

    uint8_t thermo_check_fault ( thermo_t* ctx );

  • Function reads the 32-bit of data from the sensor.

    uint32_t thermo_read_data ( thermo_t* ctx );

Examples Description

This example measures temperature and then logs the results.

The demo application is composed of two sections :

Application Init

Initializes driver and start write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo_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 ----" );

    thermo_cfg_setup( &cfg );
    THERMO_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo_init( &thermo, &cfg );

    if ( thermo_check_fault( &thermo ) )
    {
        display_error_msg();
    }
    else
    {
        log_printf( &logger, "Status OK\r\n" );
    }

}

Application Task

Temperature measured by the thermocouple is converter and the results are logged.


void application_task ( void )
{
    temperature = thermo_get_temperature( &thermo );

    log_printf( &logger, "Temperature : %f\r\n", temperature );

} 

Note

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.Thermo

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.

Oximeter 5 Click is a compact add-on board suitable for measuring blood oxygen saturation. This board features the MAX30102, integrated pulse oximetry, and heart-rate monitor module from Analog Devices. The MAX30102 includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. It operates on a single 1.8V power supply acquired from both mikroBUS™ power rails for the internal LEDs, communicating through a standard I2C compatible interface. The MAX30102 can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
