Library Description

Library contains generic functions for working with the click board.

Key functions:

• void thermo8_setResolution(uint8_t rCfg) - Function for setting the measurement resolution.
• uint8_t thermo8_aleGet() - Function for returning the state of the alert pin.
• float thermo8_getTemperatue() - Function for reading the temperature.

Examples description

The application is composed of the three sections :

• System Initialization - Initialize the GPIO, I2C and LOG structures.
• Application Initialization - Initialize the communication interface and configure the click board.
• Application Task - Wait for the interrupt pin to be triggered. When the measured temperature breaches the upper or lower limit the temperature value as well as the status of the breach is is shown on the serial port (UART).

void applicationTask()
{
   float T_Data;
   char text[15];
   char alert;
   char alertOn;

   Delay_ms(2000);
   alert = thermo8_aleGet();

   if(alert == 0)
   {
      T_Data  = thermo8_getTemperatue();
      alertOn = thermo8_getAlertstat();
      FloatToStr(T_Data,&text[0]);
      text[5] = 0;
   }

   if(alertOn & THERMO8_TLOWER_REACHED)
   {
      mikrobus_logWrite("Temperature under the low limit: ",_LOG_TEXT);
      mikrobus_logWrite(&text[0],_LOG_TEXT);
      mikrobus_logWrite("°C",_LOG_LINE);
   }

   if(alertOn & THERMO8_TUPPER_REACHED)
   {
      mikrobus_logWrite("Temperature over the high limit: ",_LOG_TEXT);
      mikrobus_logWrite(&text[0],_LOG_TEXT);
      mikrobus_logWrite("°C",_LOG_LINE);
   }
}

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
