LCD 3 fire?

Recommended Posts

Exista Lcd (16x2) care sa aibe doar 3 fire? si anume:

 

"The LCD module has three wires: +5 V (red), GND (black or brown), and a

serial in line (white). The baud rate may be set to 300, 1200, 2400, or 9600 by

using a set of jumpers (J1, J2, and J3) on the back of the LCD display." din PIC Robotics McGraw-Hill 2004.

 

Am vazut acolo o schema cu un pic 16F84 care era conentat la LCD printr-o singura legatura(serial in line (white)). Programul de afisare era facut in picbasic iar ce se afisa pe lcd se scotea printr-un singur pin al picului.

Tipul lcd-ului:TRULY MCC162B3-1

Cam asa ceva http://www.seetron.com/slcds.htm si se numeste

LCD Serial Controller, nu se gaseste asa ceva in Romania, nu?:smt005

 

 

Multumesc.

Asa cum se poate vedea si din poze: se ia un display "normal" si i se ataseaza un "serializator". Se poate face asa ceva. Sunt scheme la 3 si chiar la 2 fire. De xemplu: http://www.myke.com/lcd.htm

Vezi ca ai pus din greseala la sfarsitul linkului un punct. Si nu e acelasi lucru, ala e un LCD cu 3 fire care intra in pic iar eu vorbeam de un Serial LCD.

Pai LCD-ul tau probabil ca are inglobat serializatorul direct pe placa unde este si controlorul LCD-ului.Intr-adevar e o idee buna fiindca scapi de sarmaraie inutila si mai salvezi ceva pini din microcontroller.ALEKS
