LCD Inquiry and Help
PostPosted: Sat Mar 05, 2005 7:19 am     Reply with quote
Hi,

I got a 16x2 LCD Display with part number PVC160203PTL from PICVUE Electronics (http://www.picvue.com.tw).

My concern really is that I can't make any character to display on LCD? I follow the connection provided in the LCD.C driver from PICC Compiler where it use PortD.

My PIC18F452 is working since I made a simple routine that will blink an LED.

Anybody in the community who have use this LCD module? I guess I miss something here... the connection provided in the LCD.C utilizes the 4-bit data scheme.

BTW, anyone has a datasheet on this... I visit the site and I can't find any.

Any code drivers for this LCD module will help.

Thank u.

I guess its not PYL but rather PTL coz if you search at google.com u can find that the part number is available in some of the online store.
