Samsung KS0108

[Konrad]

I am messing with a KS0108 display. I have not had time to finish my code at the moment, but this mostly works. When I implement more functions I will post them. I thought I would post it as when I searched for example code here I couldn't find any.

// lcd.c for
// Samsung KS0108

#byte PORTA= 0x0F80
#byte PORTB= 0x0F81
#byte PORTC= 0x0F82
#byte PORTD= 0x0F83

//board specific definitins for pins
#define lcd_enable PIN_C0 //Enable pin on LCD
#define lcd_cmd PIN_C1 //Data/Command Pin 4 on LCD
#define lcd_rw PIN_C2 //Read/Write Pin 5 on LCD
#define lcd_cs1 PIN_B1 //ChipSelect1 Pin 15 on LCD
#define lcd_cs2 PIN_B2 //ChipSelect2 Pin 16 on LCD
#define lcd_rst PIN_C5 //Reset Pin 17 on LCD

#byte lcd_data = PORTD //ensure PORTD is declared as a byte
#use fast_io(D)

#define LCD_LEFT 1
#define LCD_RIGHT 0

void lcd_init(void);
void lcd_write(int1 half);
void lcd_gotoxy(int8 x, int8 y);
void lcd_clrscr(void);
void lcd_newline(void);

I can't get this code to compile. The structure fonts is to big. What processor were you guys using. My CCS says structures casn only go up to 256. Let me know.. TTY

[Mark]

From the addresses of the ports, I would say that this is probably an 18 series pic.

[curt2go]

Hey "me" can you post the bmp.c so I can try it out. I went to that site. Cool stuff but could not find the file.. Thanx .. TTY

[Konrad]

This file must contain 1024 char's
My own logo is here, so I have not posted a full array.
From the site I have previously posted,
download and run glipic, and add the appropriate header & footer.

I till have not had time ti finish this code, but I plan to post graphical plotting similar to borland turbo c or quickc.

const char bmp[1024] =
{
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x80,0x00,0x00,0x80,0x00,0x00,0x00,0x80,0x80,

I have not done much work since, I found out that actually ccs glcd example is actually for the KS0108, though they didn't say so
hope this helps

ps both drivers will work at the same time i.e. use mine for the bitmap (it is quicker) and the ccs driver for plotting or large fonts etc

[Guest]

Where is the main program ?
Is this just the driver ?
How can i write say PICMICRO Forum on the display
could you just do an example

[BOB_SANTANA]

Here is an Example of writting text
to make the text smaller just change the 2 in the glcd_text57 () to 1 to get 5x7

[Guest]

Thanks Bob

For your example
i now understand howto send text (Thanks very much)
Now if its not too much can you please explain to me how to send values
like example say the value of int value = 100
How do i display this as i can't seems to understand the

displayVoltage(value1); is used to display the value

[BOB_SANTANA]

Hi here is a program example for you to display number
i program just counts from 0-200
BTW i still haven't figured how to clear the screen without having to use
glcd_init(OFF)
for example with this program you would notice that i really only have to clear the data after the =sign so if there is anyone out there i hope they can help i am still learning like you sorry

[Guest]

Thanks Bob

I do hope someone would explain it to me its driving me mad here

[ckielstra]

[ckielstra]

[Guest]

Its the part of clearing the lcd without having to clear everthing

Cheers
