Do you have a non-flash video like a .AVI or .WMV? My PC is flash disabled.

Right click and save as:

EDIT: Just fixed file should work well!

hi, everyone. I got to this thread through google. I have been working on the same display over the last couple days and would love to share it with folks here and get some help as well.

My code came from a CCS package I got on the web. I then adapted it for PICC (12f675) and then I decided that for what I wanted to do (as a prototype of a little portable scope), I needed something faster. so I went to ARM7. the code is compiled under Keil uvision3, mdk3.70.

I haven't figured out a way to post code so I will just put up a picture of the program running on proteus.

it works fine but has trouble displaying lower case letters some of the times so I am working through that right now. the display allows attributes (normal, overline, underline, strike, and reverse) to be attached to each string to be displayed.

two issues with the program now:

1) it doesn't display some of the lower case letters some of the times. see the red arrow. it should have displayed "hello, world", all in lower case but it is been shifted by 1 letter.

2) it has some remaining lines on the last line (page 8, d0, per the datasheet). now sure how data go there.

i will post the code once I figure out how to do so.

as for the arrow you:

You either have a extra character in the beginning of your font table or you are minus-ing the wrong amount from it.

To place code here just put the code in these brackets

[ code] CODE here [ /code]

remove the spaces within the brackets. You will then see it like:

Code:

or you can upload a ZIP or C or H file.

To upload you have to be in Advanced Mode [Go Advanced] button on the bottom right of quick reply

do me 1 favor try printing this to the LCD:

Code:

		lcd_gotoxy(1,0);
		lcd_str("XYZ[\]^_`abc", NORMAL);

This should help me think better. Show a image when done please.

AtomSoft · 18th June 2009, 12:10 AM

oh and for the extra bits that appear in bottom left try clearing the screen before first write.

Try this as your main:

Code:

/*****************************************************************

*****************************************************************/

int main(void)
{
 
    mcu_init();

	while (1) {
//	     lcd_chr('c');
//	     lcd_chr('b');

            lcd_cls();
            lcd_gotoxy(0,0);
            lcd_str("0- XYZ[\]^_`abc", NORMAL)

//	     lcd_str("0-HELLO, WORLD!", NORMAL);

            lcd_gotoxy(1,0);
            lcd_str("1-01234567890012", NORMAL);

            lcd_gotoxy(2,0);
            lcd_str("2-hello, world!", OVERLINE);

            lcd_gotoxy(3,0);
            lcd_str("3-ABCDEFGHIJKLMN", UNDERLINE);

            lcd_gotoxy(4,0);
            lcd_str("4-abcdefghijklmn", STRIKE);

            lcd_gotoxy(5,0);
            lcd_str("5-OPQRSTUVWXYZ", OVERLINE | STRIKE);

            lcd_gotoxy(6,0);
            lcd_str("6-opqrstuvwxyz", UNDERLINE | STRIKE);

            lcd_gotoxy(7,0);
            lcd_str("7-  BYE BYE", STRIKE | OVERLINE | UNDERLINE | REVERSE);

//	     lcd_cls();
	}
}

if I change the code to

Code:

lcd_str("XYZ[\\]^_`abc", NORMAL);

note the "\\" because "\" is the escape sequence in C.

the output is perfectly normal.

[/code]

the dots at the bottom of the screen has something to do with the 7110 model in proteus, I suspect.

If I turn comm to normal, in lcd_init():

Code:

lcd_write_command(comm_reverse); // (15) common output normal (0xC8 reverse)

I get a flipped but otherwise fine screen.

here is how to make the 'a' disappear,

.

Code:

		lcd_gotoxy(0,0);
   	lcd_str("0-XYZ[\\]^_`abc", NORMAL);
		lcd_gotoxy(1,0);
		lcd_str("1-XYZ[\\]^_abc", NORMAL);

try removing some of the comments from the font

Code:

                  0x00,0x41,0x41,0x7f,0x00,  // 5d ]
                  0x04,0x02,0x01,0x02,0x04,
                  0x40,0x40,0x40,0x40,0x40,

                  0x20,0x54,0x54,0x54,0x78,  // 61 a

Im not sure why you get this issue. I have comments also but no issue like this. would it be possible for you to post the proteus model and stuff so i can check it here?

sure. see attached.

eliminating the comments made no difference. also, have you noticed that the char ']' was not displaced at all?

Jason, your instinct was right. I used lcd_chr() to trace the problem back to char 5c, '\', which is a control char for c. I rewrote that line from:

Code:

0x02,0x04,0x08,0x10,0x20,  // 5c \

to

Code:

0x02,0x04,0x08,0x10,0x20,  // 5c 55

and everything is golden!

thank you so much for your help.

millwood	hi, everyone. I got to this thread through google. I have been working on the same display over the last couple days and would love to share it with folks here and get some help as well. My code came from a CCS package I got on the web. I then adapted it for PICC (12f675) and then I decided that for what I wanted to do (as a prototype of a little portable scope), I needed something faster. so I went to ARM7. the code is compiled under Keil uvision3, mdk3.70. I haven't figured out a way to post code so I will just put up a picture of the program running on proteus. it works fine but has trouble displaying lower case letters some of the times so I am working through that right now. the display allows attributes (normal, overline, underline, strike, and reverse) to be attached to each string to be displayed. two issues with the program now: 1) it doesn't display some of the lower case letters some of the times. see the red arrow. it should have displayed "hello, world", all in lower case but it is been shifted by 1 letter. 2) it has some remaining lines on the last line (page 8, d0, per the datasheet). now sure how data go there. i will post the code once I figure out how to do so.

AtomSoft	as for the arrow you: You either have a extra character in the beginning of your font table or you are minus-ing the wrong amount from it. To place code here just put the code in these brackets [ code] CODE here [ /code] remove the spaces within the brackets. You will then see it like: Code: Code Here or you can upload a ZIP or C or H file. To upload you have to be in Advanced Mode [Go Advanced] button on the bottom right of quick reply __________________ AtomSofts eBay Store AtomSoftTech: C18 TIPS & TRICKS v9 PDF My Name: Jason Lopez http://atomsofttech.info/ \| My YouTube Videos!

AtomSoft	do me 1 favor try printing this to the LCD: Code: lcd_gotoxy(1,0); lcd_str("XYZ[\]^_`abc", NORMAL); This should help me think better. Show a image when done please. __________________ AtomSofts eBay Store AtomSoftTech: C18 TIPS & TRICKS v9 PDF My Name: Jason Lopez http://atomsofttech.info/ \| My YouTube Videos!
