initializing command for CGM 064128f

[anjaz]

hi,

AM trying to configure CGM 064128f Graphical lcd i need to get the initializing commands of this LCD(HEX code)

i will b thankful if u culd mail me the details .............
with the purpose of the HEX code u suggested

i have the datasheet with me available but am trying to configure graphical lcd first time so needed only the improtant commands the HEX codes needed to initialize the Graphical LCD .........

This demonstration code:

Should work with a KS0713.

Look in the source zip file for "CFAX_WINTESTDlg.cpp". Within that file you need "OnInitialize()":

typedef unsigned char ubyte;

ubyte
  control;  //value of "*port_control_address"

#define DATA_ADDR (port_data_address)
#define CONT_ADDR (port_control_address)

//inverted at the port
#define CLR_RD (DlPortWritePortUchar(CONT_ADDR,(control|=0x01)))
#define SET_RD (DlPortWritePortUchar(CONT_ADDR,(control&=~0x01)))
  
//inverted at the port
#define CLR_WR (DlPortWritePortUchar(CONT_ADDR,(control|=0x02)));(Sleep(1))
#define FCLR_WR (DlPortWritePortUchar(CONT_ADDR,(control|=0x02)))
#define SET_WR (DlPortWritePortUchar(CONT_ADDR,(control&=~0x02)))
  
//straight at the port
#define SET_RS (DlPortWritePortUchar(CONT_ADDR,(control|=0x04)))
#define CLR_RS (DlPortWritePortUchar(CONT_ADDR,(control&=~0x04)))

//inverted at the port
#define CLR_RES (DlPortWritePortUchar(CONT_ADDR,(control|=0x08)))
#define SET_RES (DlPortWritePortUchar(CONT_ADDR,(control&=~0x08)))

#define DATA(x) (DlPortWritePortUchar(DATA_ADDR,(x)));(Sleep(1))
#define FDATA(x) (DlPortWritePortUchar(DATA_ADDR,(x)))
