Two LCD 2004 on one Wemos d1 mini ?

#1 Post by Beowolf » 30 Jul 2020, 18:18

Hello everybody,

I would like to connect two or more LCD displays to a Wemos d1 mini. On the Wemos is ESPEasy Mega.
I don't really know how to address multiple displays. It is set with "Display - LCD2004".

Each display has a different address, of course. I can only address row and column via web address. For example:

http: //192.168.xx.xx/control? cmd = lcd, 3.1, Test:

How do I send this to LCD 2?

greetings
Manfred

Right now, there does not seem to be support to send out a command to an LCD module on a specific task, or to address a "2nd" or later module.

As a matter of fact, based on how the task data is handled in that plugin, I doubt the plugin will work at all (as expected) with multiple instances of the same plugin.

Now that I2C multiplexers and multiple instance configuration for many (I2C) devices is implemented, and recently the "[taskname]." prefix PR 3198 has been merged, this is now available after upgrading to a recent release (20210114 or newer).
