sed1330fba

Hi,

I’m having problem with graphic controller SED1330FBA connected to Seiko G2436 graphic LCD. Anyone have the sample code to initialize this configuration?

Any help or pointer will be appreciated.

Thanks & regards,

Hi wh,

I've used SED1330 + data vision 32240.
Its similar than G2436 ?
whats your problem ?

Thank you very much for your response.

G2436 is 240x64 dots/pixel. I search google and know that 32240 is 320x240 dots.

OK it seems different. But my problem is I don't understand how to calculate various parameters that needed to initialize the LCD controller. The example shown in S1D13305(or SED1330) seems to be very confusing. May be I was missing something.

Best regards,
wh

Hi dainis & all who reply,

Thanks a lot for the response.

Actually I did read the technical manual before I post this thread. But it was an unsuccessful attempt since I couldn’t understand the application notes section. Since all mention the technical notes, I take another look at it. Still unsuccessful.

Following is what I get:

1) When power is on, I brought all RES, CS, RD, WR, and A0 to high. After 100uS, I set RES to low for more than 1mS, this is described as reset in the datasheet. At this point, the display was clear and I can see some flipping on LCD. (My guess the reset operation was successful).
2) Next I start to send system initialize parameter to SED1330.
Following is a summary:

Command: SYSTEM_SET
P1 0x38 ; M0: Internal CGROM
; M1: CGRAM is 32 char maximum
; M2: 8 lines per char
; W/S: Single-panel drive
; IV: No top-line compensation
P2 0x87 ; [FX]: 8
; WF: 2-frame AC drive
P3 0x07 ; [FY]: 8
P4 0x1D ; C/R: character per line
P5 0xC0 ; TC/R:
P6 0x27 ; L/F:
P7 0x28 ; APL(8)
P8 0x00 ; APH(8)

After this command, the LCD became all black, and I wonder there is something wrong with my calculation.

May someone explain how to calculate various parameters needed for the operation of SED1330, please?

I’m using LCD from Seiko (G2436, 240 x 64 pixel). The crystal on the controller board is 10MHz.

Thanks & regards,

This is an init sequence I've used, maybe it might be of some help.

Code: 
void InitLCD(void)
{
 // system set
 WriteCtrl(0x40);
 WriteData(0x30);        // P1   -> PRT=0, IV=1, W/S=0, M0-M2=0
 WriteData(0x80 + (fontsize-1));        // FX   -> WF=1, FX=7
 WriteData(0x07);        // FY   -> FY=7
 WriteData(character_per_row-1 );     // C/R  -> Char per line - 1
 WriteData((xtal / 70 / ypixels-1) / 9 );     // TC/R -> ( f_osc / f_frame / [L/F] - 1 ) / 9
 WriteData(ypixels-1 );       // L/F  -> Line per graphic screen - 1 (127)
 WriteData(character_per_row );         // APL  -> Virtual screen low byte ( char per line)
 WriteData(0);          // APH  -> Virtual screen low byte

 // scroll
 WriteCtrl(0x44);
 WriteData(T_BASE & 0xFF);
 WriteData(T_BASE >> 8);
 WriteData(ypixels-1 );

 WriteData(G_BASE & 0xFF);
 WriteData(G_BASE >> 8);
 WriteData(ypixels-1 );

 // cursor direction
 WriteCtrl(0x4c);

 // horizontal scroll pos
 WriteCtrl(0x5a);
 WriteData(0x00);

 // cursor write
 WriteCtrl(0x46);
 WriteData(0x00);        // low byte
 WriteData(0x00);        // high byte

 // overlay
 WriteCtrl(0x5b);
 WriteData(0x01);

 // display on/off
 WriteCtrl(0x59);        // display on
 WriteData(0x14);        // layers 1 + 2

 /*
 // cursor format
 WriteCtrl(0x5d);
 WriteData(0x07);        // width
 WriteData(0x87);        // height and type
 */
}
