EW32FA3FLW 320*240 LCD

[Csiffary Zsolt]

Sziasztok!

Ujra elovettem az EW32FA3FLW 320*240 LCD-t, ennek a felelesztesevel
probalkozom. Persze most sem indul el. Tudna Valaki segiteni benne? Hol
rontom el? A lenti programnak kellen inicializalni az LCD-t es kiirni hogy
EPSON. Minta program, egy doksiban talaltam...

Van valakinek valamilyen mukodo programja (PIC, AVR vagy barmi mas
kontroller) ami bekapcsolja az LCD-t, kiir ra valamit? Legyszi kuld el
nekem!

Elore is koszi, Zsolt


Szerintem a BEKOTESE???

1- VSS
2- VDD
3- N.C.
4- A0
5- WR
6- RD
7-14- D0-D7
15- CS
16- RST
17- VEE
18- SEL1
19- VLED
20- VLSS

Ezt talaltam hozza.

PIC-cel probalom eleszteni, eddig nem sok sikerrel.
Parancs es adat irast a kovetkezo rutin vegezne:

A busy flag olvasa, D6 H- belso ciklusban van. Uresen tesztelve az LCDBUSY
