Using a parallel LCD(44780 based) as a serial LCD

[Art]

It sounds like OP thinks LCDOUT is serial, so trying to make the LCD module serial to accommodate that.
If it’s a matter of not enough IO pins to use parallel, a shift register would at least take care of the data lines.
You’d probably need an extra pin. The data pins are already supposed to be in their state when the enable pin transitions.

Hi All,
Yes I was confused with the use of LCDOUT and SEROUT and SEROUT2.
Thanks for the info and explanations.
