just alter or copy the original "PutChar" function and edit it to the new font and change the size for the font.

Hy,
I'm stuck, I still can not display a large print, or "float" with the function of Pommie:

Code:

void ftoa(float f,char* String,char Places){
long power;
char n,i;
    power=1;
    while(power*10<=f)
        power*=10;
    while(power>=1){
        n=(char)(f/power);
        f-=n*power;
        power/=10;
        *String++=n+'0';
    }
    *String++='.';
    for(i=0;i<Places;i++){
        f*=10;
        n=(char)f;
        f-=n;
        *String++=n+'0';
    }
    *String=0;
}

How to use this function to convert a float into a string and display it with the GLCD library?

And my second problem, I tried to understand how the display using the putchar function to create my display large font (I need to display from 0 to 9 and the dot ".".
Could you help me, because I'm stuck for a few days, and your support since the beginning helped me a lot, and I hope that this will continue..

Thank You

Hi,

I encounter a problem:
I can not write where I want on the axis "y", I still lag 8.i only write on the lines 0, 8, 16, ... even if I do:

Code:

SetPos(50,7); 
PutChar('R');

he writes to the line 0.

Is it possible to solve this problem?
Thank you in advance

Hi,

I have a little problem (yes another!), concerning to display a float ..
this is what I do:

Code:

# include <ftoa.h>
...
float voltage;
DataToLcd char [30];
...
voltage = 30.2359;
ftoa (voltage, DataToLcd, 2);

and after that, I have my "char" DataToLcd which is "30.23" is:
DataToLcd [0] ='3 '
DataToLcd [1] ='0 '
DataToLcd [2] = ''.
DataToLcd [3] ='2 '
DataToLcd [4] ='3 '
DataToLcd [5] = ''.
...
DataToLcd [29] = ''.

but then how to display it:
I do fine:

Putchar (DataToLcd);
PutMessage (DataToLcd);

it does not work!

you have an idea?

Thank you in advance

Pommie · 9th April 2009, 10:48 AM

Something like,

Code:

    i=0;
    while(DataToLcd[i]!=0)
        PutChar(DataToLcd[i++]);

Mike.

Pommie thank you ... it works very well ...
Will you have an idea on my previous post on the writing area on the screen. By the coordinate "y" must always be a multiple of 8? can we change this?
Thank you again

Pommie · 10th April 2009, 03:54 AM

It is possible to write characters to any position on the screen. The way to do it is to load each vertical byte of the character into a 16 bit variable and scroll it the required number if pixel (0-6). You then inclusive or this with the screen to draw the character.

Mike.

Hi Pommie,

can you tell me what level of the library I need to change something in order to write where I want?

I can not..

Thank you in advance

jorg1n · 20th April 2009, 03:20 PM

Hi,
I looked again the principle of transmission, and features in the documentation of my display, and I think the solution lies in this function and in the last line:

Code:

void WritePosition(void){
	if(XPos>63){
		b_GLCD_GCS1=1;
		b_GLCD_GCS2=0;
	}
	else{
		b_GLCD_GCS1=0;
		b_GLCD_GCS2=1;
	}
	GLCD_Write_Cmd(0x40+(XPos&0x3f));	//column=0
	GLCD_Write_Cmd(0xb8+((YPos&0x3f)>>3));	//row=0		//row=0	
}

But I can not change it correctly to write to all the lines ...

Can you help me please
Thanks a lot

Pommie · 20th April 2009, 03:49 PM

The routine that needs rewriting is the PutChar routine. Unfortunately, the changes required are extensive and I don't have the time to help.

You could write a slower version that looked at each byte of the char and used the plot routine to draw it.

Mike.

Hi,

Pommie, have you received my MP?
can you answer my message MP, even if the answer is no?
Thank you in advance.

PS: attached documentation of my display, as on page 12, I looked at the controls and I find it odd that in the WritePosition, when we want to set the value of Y using the direction of X and vice versa.

Thank you again

jorg1n · 23rd April 2009, 07:05 AM

Hi,

For display on all "y" axes, I dropped (I failed ...), I do otherwise.

For against, I'm still stuck on the display of a larger police, are what you could help me please.

Thank you in advance
