A Node-RED node to control a Pimorini Pi-LITEr 8 LED add-on board for a Raspberry-Pi.
Run the following command in the root directory of your Node-RED install
npm install node-red-node-piliter
Requires the WiringPi gpio command to be installed in order to work. See the WiringPi site for details on how to do this.
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.
{led:3,state:0}to set LED3 off.
