Click library

• Author : MikroE Team
• Date : Jun 2020.
• Type : GPIO type

Software Support

We provide a library for the Sht1x 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 Sht1x Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void sht1x_cfg_setup ( sht1x_cfg_t *cfg );

  - Initialization function.

  ‍SHT1X_RETVAL sht1x_init ( sht1x_t *ctx, sht1x_cfg_t *cfg );

• Click Default Configuration function.

  ‍void sht1x_default_cfg ( sht1x_t *ctx );

Example key functions :

• Set pin on output.

  ‍void sht1x_output_sda ( sht1x_t *ctx, sht1x_cfg_t *cfg );

  - Set pin on input.

  ‍void sht1x_input_sda ( sht1x_t *ctx, sht1x_cfg_t *cfg );

• Set SDA high function.

  ‍void sht1x_sda_high ( sht1x_t *ctx );

  Examples Description

‍This click measures temperature and humidity.

The demo application is composed of two sections :

Application Init

‍Initialization driver enables GPIO.

void application_init ( void )
{
    log_cfg_t log_cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info(&logger, "---- Application Init ----");
 
    sht1x_cfg_setup( &cfg );
    SHT1X_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    sht1x_init( &sht1x, &cfg );
}

Application Task

‍This example demonstrates the use of SHT1x Click board by measuring temperature and humidity, and displays the results on USART terminal.

void application_task ( void )
{
    sht1x_read_results( &temperature, &humidity );
    log_printf( &logger, " Temperature: %.2f ", temperature );
    log_printf( &logger, " C \r\n" );
  
    log_printf( &logger, " Humidity: %.2f ", humidity );
    log_printf( &logger, " %% \r\n", humidity );
    
    Delay_ms ( 1000 );
}  

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.Sht1x

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.
