Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
Raspberry Pi-LITEr output node. The Pi-LITEr must be fitted.

|
||
|
|
Operates in one of 5 different modes :
|
||
|
|
|
||
|
|
- Byte Mode - expects a value between 0 and 255, and each of the LEDs represent 1 bit.
|
||
|
|
- Meter Mode - expects a value between 0 and 8, the led lit corresponds to the input value - like a meter needle.
|
||
|
|
- Bar Mode - expects a value between 0 and 8, similar to meter - but all the leds up to the value are turned on - like a mini bar chart.
|
||
|
|
- All LEDs Mode - expects a 1 or 0 - turns on and off ALL the LEDs
|
||
|
|
- Object Mode - expects a object specifying the LED and state eg. <code>{led:3,state:0}</code> to set LED3 off.
