Read cursors position on LCD?

[lab310]

Yes , found that info too, but I'm using 4-bit connection to LCD so this won't work. No one mentions if this is possible when using 4bit instead of 8.
I have complex manu map, and could to some things much easier if I knew possition of cursor .

Well.... you could try connecting the R/W line, assign a 2nd pin to the RS bit, put it and the existing RS pin line thru an AND gate (two Diodes and a Resistor would suffice) to the LCD, drive the new RS bit pin Low (forcing LCD RS Low) and then issue an LCDIN instruction... Do you feel lucky?

Lab,

do you really want to pay this price?

As Melanie already said, it is the PIC controlling the LCD, so how can you loose the cursor position?
