Library Description

The library covers all functionalities of the click board.

Key functions:

float temphum4_getTemperature() - Read temperature form sensor

float temphum4_getHuminidy() - Read humidity from sensor

void temphum4_Configuration(uint16_t _data) - Configure sensor

Examples Description

The application is composed of three sections:

 

  • System Initialization - Initializes I2C module and CS pin, RST pin as OUTPUT and INT pin as INPUT.
  • Application Initialization - Initializes Driver init and settings chip mode ACTIVE and configuration measurement.
  • Application Task - (code snippet) - Reads the temperature and huminidy and logs to the USBUART every 500 ms.

 

void applicationTask()
{
 Temperature = temphum4_getTemperature();
 Huminidy = temphum4_getHuminidy();

 FloatToStr(Temperature,temp_txt);
 mikrobus_logWrite("Temperature : ",_LOG_TEXT);
 mikrobus_logWrite(temp_txt,_LOG_LINE);

 FloatToStr(Huminidy,hum_txt);
 mikrobus_logWrite("Huminidy : ",_LOG_TEXT);
 mikrobus_logWrite(hum_txt,_LOG_LINE);

 Delay_ms( 500 );
}

Other mikroE Libraries used in the example:

  • I2C
  • UART
  • Conversions

Additional notes and information

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.

USB UART click

Simple example which demonstrates working with &lt;b&gt;USB UART&lt;/b&gt; click board in mikroBUS form factor. This code demonstrates how to use uart library routines. Upon receiving data via RS232, MCU immediately sends it back to the sender.

Stretch click

Stretch click is a mikroBUS add-on board with circuitry for measuring stretch forces with conductive rubber cords. The click has screw terminals for connecting 2mm-diameter and 1m-long conductive rubber cord. The resistance of the chord increases when stretched, impacting the voltage available on the AN pin.
