Click library

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

Software Support

We provide a library for the Thermo9 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 Thermo9 Click driver.

Standard key functions :

• Config Object Initialization function.

void thermo9_cfg_setup ( thermo9_cfg_t *cfg );

• Initialization function.

THERMO9_RETVAL thermo9_init ( thermo9_t *ctx, thermo9_cfg_t *cfg );

Example key functions :

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

void thermo9_send_cmd ( thermo9_t *ctx, uint8_t cmd_byte );

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

void thermo9_calibation ( thermo9_t *ctx );

• Function is used to read temperature in degree centigrade.

float thermo9_read_temp ( thermo9_t *ctx );

Examples Description

This demoapp measures temperature every 3 seconds.

The demo application is composed of two sections :

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( 2000 );
}  

Note

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

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.Thermo9

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.
