Detailed Description
SiTI DM632/DM633/DM634 16-channel, 16-bit PWM constant-current LED driver
Constructor & Destructor Documentation
◆ Dm632() [1/2]
| Dm632 | ( | Spi | SpiModule, |
| SpiChipSelectPin | LatchPin, | ||
| double | speedMhz = 6 |
||
| ) |
Construct a DM632 16-channel, 16-bit PWM LED controller attached directly to an SPI port
- Parameters
-
SpiModule The SPI module to use LatchPin The latch pin to use speedMhz The speed, in MHz, to use
◆ Dm632() [2/2]
| Dm632 | ( | ChainableShiftRegisterOutput | upstreamDevice | ) |
Construct a DM632 16-channel, 16-bit PWM LED controller attached to the output of another shift register
- Parameters
-
upstreamDevice The shift register this DM632 is attached to
Member Function Documentation
◆ Clear()
| Task Clear | ( | ) |
Clear the outputs of all LEDs
- Returns
- An awaitable task that completes upon success
Implements ILedDriver.
◆ updateFromCurrentValue()
|
protectedvirtual |
Set the individual LED brightness values based on the direct value written to this register
Note that the state is always set to true when this is called; only the brightness is adjusted
Implements ChainableShiftRegisterOutput.
◆ FlushAsync()
|
inherited |
Flush data to the port
- Parameters
-
force Whether to flush all data to the port, even if it doesn't appear to have changed.
- Returns
- An awaitable task that completes when finished
Implements IFlushable.
◆ Write()
|
inherited |
Immediately update all the pins at once with the given value.
Flush() will be implicity called.
- Parameters
-
value A value representing the data to write to the port
- Returns
- An awaitable task that completes upon successfully writing the value.
◆ FlushIfAutoFlushEnabled()
|
protectedinherited |
Classes extending this class should call this function after the internal pin data structure is updated.
- Returns
Member Data Documentation
◆ HasGlobalBrightnessControl
| bool HasGlobalBrightnessControl => true |
Gets whether this display has global brightness control (Hint: it does!)
◆ HasIndividualBrightnessControl
| bool HasIndividualBrightnessControl => true |
Gets whether this display has individual brightness control (which it does!)
Property Documentation
◆ Brightness
|
getset |
Gets or sets the brightness of the display
The DM632 has no global brightness control, so this property emulates this functionality by scaling each LED's output value by this value.
◆ Leds
◆ Children
|
getsetinherited |
◆ CurrentValue
|
getprotected setinherited |
The current value of the port
◆ AutoFlush
|
getsetinherited |
Whether or not written data should automatically be flushed to the controller
◆ Parent
|
getprotected setinherited |
The parent shift register (if not null) this device is attached to
