Constructor & Destructor Documentation
| MicroBitLightSensor | ( | const MatrixMap & | map ) |
Constructor.
Create a representation of the light sensor.
- Parameters:
-
map The mapping information that relates pin inputs/outputs to physical screen coordinates. Defaults to microbitMatrixMap, defined in MicroBitMatrixMaps.h.
Definition at line 84 of file MicroBitLightSensor.cpp.
| ~MicroBitLightSensor | ( | ) |

Member Function Documentation
| int read | ( | ) |
This method returns a summed average of the three sections of the display.
A section is defined as: ___________________ | 1 | | 2 | | 3 | |___|___|___|___|___| | | | | | | |___|___|___|___|___| | 2 | | 3 | | 1 | |___|___|___|___|___| | | | | | | |___|___|___|___|___| | 3 | | 1 | | 2 | |___|___|___|___|___|
Where each number represents a different section on the 5 x 5 matrix display.
- Returns:
- returns a value in the range 0 - 255 where 0 is dark, and 255 is very bright
Definition at line 120 of file MicroBitLightSensor.cpp.
| void startSensing | ( | MicroBitEvent | ) |
The method that is invoked by sending MICROBIT_DISPLAY_EVT_LIGHT_SENSE using the id MICROBIT_ID_DISPLAY.
- Note:
- this can be manually driven by calling this member function, with a MicroBitEvent using the CREATE_ONLY option of the MicroBitEvent constructor.
