Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in the register. The library includes the function for configuration chip for measurement, functions for reading temperature, channel (X or Y or Z) data. The user also has the function float color6_convertingToEe(uint8_t channel, uint16_t MRES_data) which converts channel data to Ee (Input light irradiance regarding to the photodiode’s area within the conversion time interval) data.

Key functions:

• uint16_t color6_readData(uint8_t reg) - Functions for reading data from register
• float color6_convertingToEe(uint8_t channel, uint16_t MRES_data) - Functions for converting channel data to Ee data.
• void color6_goToMeasurementMode() - Functions for go to measurement mode.
• float color6_getTemperature() - Functions for reading temperature in ℃.

Example description

The application is composed of three sections:

• System Initialization - Initializes I2C module.
• Application Initialization - Initializes driver init and configuration chip for measurement.
• Application Task - (code snippet) - Reads values from the X / Y / Z channel and converts to Ee (input light irradiance regarding the photodiode’s area within the conversion time interval) data. This data logs on USB UART every 2 seconds.

void applicationTask()
{
 mikrobus_logWrite(" Channel X : ",_LOG_TEXT);
 X_data = color6_readData(_COLOR6_MREG_MEASUREMENT_X_CHANNEL );
 IntToStr(X_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Ee X channel data: ",_LOG_TEXT);
 Ee_data = color6_convertingToEe(_COLOR6_MREG_MEASUREMENT_X_CHANNEL, X_data);
 FloatToStr(Ee_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Channel Y : ",_LOG_TEXT);
 Y_data = color6_readData(_COLOR6_MREG_MEASUREMENT_Y_CHANNEL );
 IntToStr(Y_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Ee Y channel data: ",_LOG_TEXT);
 Ee_data = color6_convertingToEe(_COLOR6_MREG_MEASUREMENT_Y_CHANNEL, Y_data);
 FloatToStr(Ee_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Channel Z : ",_LOG_TEXT);
 Z_data = color6_readData(_COLOR6_MREG_MEASUREMENT_Z_CHANNEL );
 IntToStr(Z_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Ee Z channel data: ",_LOG_TEXT);
 Ee_data = color6_convertingToEe(_COLOR6_MREG_MEASUREMENT_Z_CHANNEL, Z_data);
 FloatToStr(Ee_data, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" Temperature : ",_LOG_TEXT);
 temperature = color6_getTemperature();
 FloatToStr(temperature, dataText);
 mikrobus_logWrite(dataText, _LOG_LINE);

 mikrobus_logWrite(" ",_LOG_LINE);
 Delay_ms( 2000 );
}

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.
