Hi all!

I have a 1602A V2.0 and have searched all part to integrate with NODEMCU. The problem is I can not find anything useful. Even I'm thinking it's impossible to make the connection and display a message even.

I would appreciate any information or contribution.

Thank you very much for your time.

Hello
I have a very similar LCD but its the 20x4 version. I used the code for the lcd1602.lua done by Vladimir.

I am able to print Hello World using this:

Code: Select all

i2c.setup(0, 4, 3, i2c.SLOW)
lcd = dofile("lcd1602mod.lua")()
lcd.light(0)
lcd.locate(0,1)
lcd.put("Hello World!")

However, I can't move the cursor, the next "put" command it adds to the end of the previous output. So, lot's still to figure out.
