Class Name

Dimmer

Description

Drive an analog pin from a DCS ranged value. Traditionally used for a dimmable LED or bulb. Reminder that most microcontrollers use PWM to achieve dimming analog outputs and this may or may not be compatible with your connected device.

Constructor 1

Dimmer(unsigned int address, char pin, int minOutput=0, int maxOutput=255)

• address - The DCS address of the value to sync to.
• pin - The analog output pin to be controlled.
• minOutput - [Optional] Used to limit the output range. Defaults to zero (always/full OFF) to map the minimum DCS value to.
• maxOutput - [Optional] Defaults to 255 (always/full ON) to map the maximum DCS value to. Do not exceed 255.

Constructor 2

Dimmer(unsigned int address, char pin, unsigned int (*map_function)(unsigned int newValue))

• address - The DCS address of the value to sync to.
• pin - The analog output pin to be controlled.
• map_function - A custom function which can be used to provide arbitrary (nonlinear, conditional, etc) mappings between DCS values and output pin values.

Example 1

DcsBios::Dimmer apuRpm(0x10BE, A0); // The brightness of an LED on pin A0 will correspond to the position of RPM of the APU.

Example 2

DcsBios::Dimmer lEngCore(0x10A8, A1, 64, 191); // The brightness of an LED on pin A1 will correspond to the position of LENG Core RPM, restricted to the middle 50% of the LED's brightness range
