Nodemcu serial to lcd display

PostPosted: Tue May 25, 2021 6:23 pm

There are serial back pack lcd's available from Scott Edwards website. I am unable to write to the display or rather get a working message. Found a Scott edwards add on for arduino on git hub but obviously doesn't compile for nodemcu. As far as I can tell the library provides serial timing for the chip. There must be timing errors without it. Does anyone have an add on for the display or working code? A simple Hello World would be great
Thanks

Excuse my ignorance, but can't you use the standard available Serial class and one of the UARTs of the ESP? :?
Or possibly, if you want to use other GPIO's for serial, softwareserial?

Tried software serial and the rest but apparently the timing doesn't work out correctly so the display is jumbled. The add on that won't compile states it does a few tricks to setup the timing correctly.

Scott Edwards has serial backpack LCDs for sale on his website. I can't seem to obtain a functional message or write to the display. On Github, I discovered a Scott Edwards add-on for Arduino, however, it clearly does not compile for nodemcu. As far as I can determine, the library manages the chip's serial time. Help me!
