epson sed1330fba
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,
