ima li neko bilo sta i touchscreenu koji prodaje mikroelektronika?

The touchscreen is connected directly to the analogue channels AN0 to AN3 of the PIC. Pull-down resistors are required on each of these pins (e.g. 10K resistors). There are a number of #options - these are documented at the start of the library.
It is the users responsibility to set up the analogue port correctly. The two sample codes below with give an example of how to do this.

Sigurno je vruca roba kad ti ne odgovaraju.
e sad mi nista nije jasno
ja sam mislio da je to touchscreen sa digitalnim izlazom...
no nebitno...
iz ovoga sto je zmedak5 poslao slabo sam razumeo kako se koristi...
koliko kontam on bi trebao da menja otpornost u zavisnosti od toga gde je pritisnut...
a sad mi se ko uz ku... istrosila baterija na oba instrumenta
znali iko ista o ovakvim touch screen-ovima?
googlao sam "4 Wire Resistive Touch Screens" ali nije bilo nista korisno...
edit:
napokon sam pronasao nesto korisno...
ako jos nekom zatreba evo link

evo uradio sam touchscreen sa displejem 16x2
na displeju ispisujem samo x i y poziciju.
rezultati i nisu nesto....
dosta je nelinearan touchscreen,
npr kad vucem po donjoj ivici x ose, menja se i x osa sto je normalno, ali se menja i y osa se dosta menja, sto je defektno
mada sve u svemu je ok.
npr kad stavim olovku na isto mesto dobijam malte ne identicne rezultate, a to mi je u ostalom i bitno...

svaka cast?
jesi to sam smislio ili je to neki projekat sa neta?
