Hello  
I am trying to send text to a 1602a LCD on raspberry pi 3+ using the Node-Red LCD node but I always get a typedError message. I have search all over for the correct format with no success. I am pretty sure the wiring is ok, I checked many times, and even redid it using other GPIO pins, but still no success ...

Here is my simple flow if it may help.  
I am using the latest version of Node-red. V 1.0.4

Cheers

Eric
