Hello!
Is it possible to the stamp the following way; ?
LCD1 connects to following:
-Pin 0: Enable
-Pin 2: R/W
-Pin 3: RS
-Pin 4-7: DB4 - DB7
LCD2 connects to following:
-Pin 1: Enable
-Pin 2: R/W
-Pin 3: RS
-Pin 4-7: DB4 - DB7
And then print out to LCD1 using the lcdout 0 command and printing to lcd2 using the lcdout 1 ?
Will the lcd1 panel turn black when it becomes disabled?
Anyone?

·· No you cannot connect two LCD Displays in that manner and get them to work.· As for I becoming black when it’s disabled…I am not sure what you mean.· When idle the display will retain its contents.· When turned off using the command it will go blank, but the display data will be intact.· If you remove power it will then need to be reinitialized before it can be written to again.· I hope this helps.· Take care.
