Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

A HD44780 parallel interface LCD is what the LCDOUT command talks to!

Re: Using a parallel LCD(44780 based) as a serial LCD
If you are going to use a "serial backpack", then instead of the LCDOUT command, you would just use SEROUT or SEROUT2
and in addition to what Art said... the LCDOUT command will work with either 4 or 8 data lines to the LCD (but you probably already knew that)

Re: Using a parallel LCD(44780 based) as a serial LCD
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.
Regards,
