Library Description

Library contains generic functions that will allow a user to easily get started with the click board.

Key functions:

• uint32_t color9_getGreen() - Return the value of the green color mesurement.
• uint32_t color9_getBlue() - Return the value of the blue color mesurement.
• uint32_t color9_getRed() - Return the value of the red color mesurement.

Examples description

The application is composed of three sections :

• System Initialization - Initialize GPIO, I2C and LOG structures.
• Application Initialization - Initialize the driver and test if the sensor is present. If the ID read from the sensor is correct execute the initialization procedure./li>
• Application Task - Wait for the color data to be available then read the data and send it to the serial port.

void applicationTask()
{
   char txt[20];
   uint8_t convComplete;
   uint32_t measurementData;

   convComplete = color9_gStatusreg();

   if( convComplete & 0x08 )
   {
      convComplete = 0;
      mikrobus_logWrite("Ir:    ",_LOG_TEXT);
      measurementData=color9_getIr();
      LongToStr(measurementData,txt);
      Ltrim(txt);
      mikrobus_logWrite(txt,_LOG_LINE);

      mikrobus_logWrite("Green: ",_LOG_TEXT);
      measurementData=color9_getGreen();
      LongToStr(measurementData,txt);
      Ltrim(txt);
      mikrobus_logWrite(txt,_LOG_LINE);

      mikrobus_logWrite("Blue:  ",_LOG_TEXT);
      measurementData=color9_getBlue();
      LongToStr(measurementData,txt);
      Ltrim(txt);
      mikrobus_logWrite(txt,_LOG_LINE);

      mikrobus_logWrite("Red:   ",_LOG_TEXT);
      measurementData=color9_getRed();
      LongToStr(measurementData,txt);
      Ltrim(txt);
      mikrobus_logWrite(txt,_LOG_LINE);

      mikrobus_logWrite("--",_LOG_LINE);
   }
}

• C_String Library

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.
