WG320240B CCS drivers
PostPosted: Sat Jan 31, 2009 9:29 am     Reply with quote
plop,

i want to use this LCD screen for a personal project
it has a S1D13305 controller, wich is compatible SED1335

as you can see in the datasheet, SEL is used for selecting 6800 or 8080 mode.

and CCS drivers were design for the 8080 mode

and i noticed something odd on my display, with my multimeter in "ringing mode" if i touch VDD and SEL it rings.

which mean i forced to use 6800 mode, can i do something about it? i mean, it's weird. what is this pin for if i can't use it

thanks

also, what is frame ground for?

well, it was forced to Vss not VDD, so no problem^^

but, i wired him up like that :



and made this code :

SED1335.c :

Code:

#ifndef GLCD_RST
#define GLCD_RST           PIN_C4
#endif

#ifndef GLCD_RD
#define GLCD_RD            PIN_c2
#endif

#ifndef GLCD_WR
#define GLCD_WR            PIN_c1
#endif

#ifndef GLCD_CS
#define GLCD_CS            PIN_c3
#endif

#ifndef GLCD_A0
#define GLCD_A0            PIN_c0
#endif


program :

Code:

#include <16F877A.H>
#fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 20000000)

#define LARGE_LCD 1
#include<sed1335.c>
#include<graphics.c>

//==========================

void main()
{
delay_ms(500);
glcd_init(ON);

   while(1)
      {

      delay_ms(500);
      glcd_fillScreen(ON);
      output_toggle(pin_c7);
      delay_ms(500);
      glcd_fillScreen(OFF);
      output_toggle(pin_c7);
      }
}


The only thing I get is vertical and horizontal line who aren't moving, they appear at a random place each time power it on.
