Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the TempHum12 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 TempHum12 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void temphum12_cfg_setup ( temphum12_cfg_t *cfg );

  • Initialization function.

    TEMPHUM12_RETVAL temphum12_init ( temphum12_t ctx, temphum12_cfg_t cfg );

  • Click Default Configuration function.

    void temphum12_default_cfg ( temphum12 *ctx );

Example key functions :

  • Temperature data

    float temphum12_get_temperature ( temphum12_t *ctx, uint8_t temp_in );

  • Relative Huminidy data

    float temphum12_get_humidity ( temphum12_t *ctx );

  • Interrupt state

    uint8_t temphum12_get_intrrupt_state ( temphum12_t *ctx );

Examples Description

This application measures temperature and humidity.

The demo application is composed of two sections :

Application Init

Initializes driver init and configuration device for measurement.


void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum12_cfg_t cfg;
    uint16_t tmp;
    uint8_t read_reg [ 2 ];

    /** 
     * 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.

    temphum12_cfg_setup( &cfg );
    TEMPHUM12_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum12_init( &temphum12, &cfg );

    temphum12_default_cfg( &temphum12 );

    Delay_ms ( 1000 );
    Delay_ms ( 500 );
    log_printf( &logger, "--- Start measurement ----\r\n" );
}

Application Task

Reads Temperature and Humidity data and this data logs to the USBUART every 1 sec.


void application_task ( void )
{
    float temperature;
    float humidity;

    temperature = temphum12_get_temperature( &temphum12, TEMPHUM12_TEMP_IN_CELSIUS);

    log_printf( &logger, "Temperature: %.2f \r\n", temperature );
    Delay_1sec( );

    humidity = temphum12_get_humidity( &temphum12 );

    log_printf( &logger, "Humidity: %.2f \r\n", humidity );

    log_printf( &logger, "-----------------------------\r\n" );
    Delay_1sec( );
}

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.TempHum12

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.

Temp&Hum 21 Click is a compact add-on board representing temperature and humidity sensing solution. This board features the HIH8130-021-001, a highly accurate, fully-calibrated digital humidity and temperature sensor from Honeywell Sensing and Productivity Solutions. This sensor, characterized by its high accuracy (±2% RH and ±0.5°C over a wide operating temperature range) and high resolution, provides factory-calibrated 14-bit data to the host controller with a configurable I2C interface. It also comes with alarm features with selectable alarm thresholds by an MCU or externally.

RFid Click - Example

0

This is a sample program which demonstrates the use of the ST's CR95HF contactless transceiver. The CR95HF is used in the applications such as near field communication (NFC) using 13.56 MHz wireless interface. In this example, when the RFid tag is put over the RFid Click antenna, the tag ID will be displayed on the TFT display.
