8 years ago There is an issue (although it goes on to work)... when I press deploy in node-red I get ... "node-red-contrib-blynk:LCD Pin already in use" this also happens every time I connect another say inject node to the lcd-print node then deploy or disconnect a node that's already connected to the lcd-print node then deploy.
this is a check i need to do better, to make sure no other widget is set on a pin, except the LCD widget. safe to ignore for now
Short tips for lcd widget are:
use advanced mode on ios set message.payload to the text you want displayed set message.topic to the line you want it shown on (0,1) set message.payload to 'clear-lcd' if you want to clear it short example using an inject node [{"id":"23f12591.81dfba","type":"blynk-server","key":"","usessl":true,"host":"","port":""},{"id":"f629c0bd.775d","type":"blynk-lcd-print","name":"","server":"23f12591.81dfba","pin":"20","x":288,"y":825,"z":"1ed41123.5fece7","wires":[]},{"id":"d31bb3f7.206a2","type":"inject","name":"","topic":"1","payload":"5","payloadType":"string","repeat":"","crontab":"","once":false,"x":92,"y":406,"z":"1ed41123.5fece7","wires":[["a431d5da.26d288","f629c0bd.775d"]]}]
please note that is just something i threw together. any suggestions on how to better do it are more than welcome
