Library for RGBW color sensor on PSOC 5LP
This example program is written with PSOC Creator 4.1. The hardware used is:
- CY8CKIT-059 PSOC 5LP Prototyping Kit
- VEML6040: RGBW color sensor with I2C interface
- standard LCD display
Warning: Be careful, when you program the PSOC. Always disconnect the PSOC from the sensor while programming. The sensor can only stand up to 3.6 V, so the 5 V from the USB connection could kill it.
You can copy only the files veml6040.h and veml6040.c into your project to use the sensor. The I2C element in TopDesign is named ICM.
| Function name | Function purpose |
|---|---|
| VEML6040_checkSensor | Check if sensor responds. If yes a 0 will be given back, otherwise a 1. |
| VEML6040_setConfiguration | Configure sensor. For further information read data sheet. |
| VEML6040_getRed | Returns the value for red light intensity. |
| VEML6040_getGreen | Returns the value for green light intensity. |
| VEML6040_getBlue | Returns the value for blue light intensity. |
| VEML6040_getWhite | Returns the value for white (= unfiltered) light intensity. |
| VEML6040_getCCT | Returns the correlated color temperature. |
| VEML6040_getAmbientLight | Returns the ambient light in lux. |
There are other functions which are used mainly in background.
