Glcd_Write_Text_Adv

[HyperUniverse]

Hi,

I am trying to use Glcd_Write_Text_Adv and Glcd_Write_Char_Adv, but it seems it doesn't work properly.

For example I want to read an ADC value and display it on GLCD.

Code: Select all

    ADCON0.ADON = 1 ;     //Turn ON the AD module
    adc_rd  = ADC_read(1);     // get ADC value from 1st channel
    ADCON0.ADON = 0 ;        //Turn OFF the AD module

    tlong = (long)adc_rd * 4990; 
    tlong = tlong / 1023;          // 0..1023 -> 0-5000mV

    ch     = tlong / 1000;     
  Glcd_Set_Font(Character8x7, 8, 7, 32);
  //   Glcd_Write_Char(48+ch, 41, 0, 1);         
    Glcd_Write_Char_Adv(48+ch, 41, 3);

    ch    = (tlong / 100) % 10;
  //  Glcd_Write_Char(48+ch, 49, 0, 1);         
    Glcd_Write_Char_Adv(48+ch, 49, 3);

    ch    = (tlong / 10) % 10;   
  //  Glcd_Write_Char(48+ch, 57, 0, 1);           
    Glcd_Write_Char_Adv(48+ch, 57, 3);
   
    Glcd_Dot(65,11,1) ;
    Glcd_Dot(66,11,1) ;
    Glcd_Dot(65,11,1) ;
    Glcd_Dot(66,11,1) ;

     ch    = tlong % 10;       // extract 0.001 volts digit
  //   Glcd_Write_Char(48+ch, 68, 0, 1);     
     Glcd_Write_Char_Adv(48+ch, 68, 3);

    Delay_ms(1);

I also use the Glcd_Write_Text_Adv command to display some Text received via UART.
And to clear the old message I had to implement a trick:

Code: Select all

     Glcd_Box(1, 44, 126, 54, 0);
    Glcd_Write_Text_Adv(UART_output, 1, 44);  // Write string

right before a string is being displayed, I create a box filled with nothing over the old text.
This seems to be working, but it takes a bit of time for the box to be created and the new string to be displayed.


With Glcd_Write_Char command it work perfect, that is every time a new character is being written on GLCD, the old one is being deleted.
But with Glcd_Write_Char_Adv command, the old character is not being deleted, and the new one is being written over the previous one, and the next character is being written over the previous two, and so on all the readings are written over the old ones, making it impossible to use.

Any help here?

Also it seems that Glcd_Write_Char_Adv is overriding the previous command: Glcd_Set_Font(Character8x7, 8, 7, 32); as the characters are NOT 8x7, but something more like 4x7???....yes, it looks like 4x7, not even 5x7

I have found an old post of filip, from mikroElektronika team, that says this:

Hi,

In order to use Glcd_Write_Text_Adv, you must create a custom font using the GLCD Font Creator Software :
http://www.mikroe.com/glcd-font-creator/

Once you have created the font, paste the generated code (array) to your project and use the font with Glcd_Write_Text_Adv routine.

Regards,
Filip.

Does this mean that Glcd_Write_Text_Adv and Glcd_Write_Char_Adv commands can not be used with variables that change while the program is running?



Thanks.

Hi,

Yes, you can use variables with the advanced GLCD functions. As Filip mentioned, they only work with fonts you create using MikroE's GLCD font creator tool (be sure to use the "Export for TFT and new GLCD" button when exporting your font). You also need to use Glcd_Set_Font_Adv() function to load the font you created. Instead of drawing a box to clear the old text, I just set the font to the background color and write over the old line then set the font back to foreground color to write the new text. Here is an quick example....sorry about the size...most of it is from the font code.

Peace,
Jim

thanks for reply Jim.

I can't make it work, there's no characters on my display.

I found another piece of info, that says to add some files to the project:

(hard_specific.c, xglcd_lib.c and propfont.h)

so I did add them, but the compiler warns me :

50 1161 Variable 'yy' has been declared, but not used xglcd_lib.c
127 1162 Variable 'CurCharDt' has been eliminated by optimizer xglcd_lib.c

what shall I do?

thanks

Hi,

I don't think you need to use the additional files (Xglcd etc) unless you have an older version of MikroC . The newer versions are already set up to use the advanced features. I assume you tried adjusting the Glcd contrast? Did you check the connections to see if they matched the ones in the code? I used the Glcd on EasyPic7 for the example...your Glcd might be connected to different pins.

Peace,
Jim

[HyperUniverse]

well, to understand better how this works, I've made it simple:

Code: Select all

//WARNING: This Font Require X-GLCD Lib.
//         You can not use it with MikroE GLCD Lib.

//Font Generated by MikroElektronika GLCD Font Creator 1.2.0.0
//MikroElektronika 2011 
//http://www.mikroe.com 

//GLCD FontName : seven8x12
//GLCD FontSize : 8 x 12

const unsigned short seven8x12[] = {
        0x08, 0x06, 0x00, 0x47, 0x08, 0x43, 0x0E, 0xC3, 0x07, 0xE3, 0x01, 0x7B, 0x00, 0x5F, 0x00, 0x0F, 0x00   // Code for char 7
        };

then I try to display number 7 with the font I just created above:

Code: Select all

void Show_Display_1() {
    Glcd_Fill(0x00)                    ;  // Clear GLCD
    Glcd_Set_Font_Adv(&seven8x12, 1, 0);
    Glcd_Write_Char_Adv('7', 31, 53);
}

but my display is blank.

what's wrong here?

seems that these files (hard_specific.c, xglcd_lib.c and propfont.h) are not needed since compiler v4.80

p.s. my display works fine with other variables that I display them as standard on pages.
I just want to be able to print some chars & text between pages too.

thanks

Ahhhh I see, it looks like you exported your font in the old style. That is why you you get the warning about requiring X-GLCD library. When you export your font from the GLCD Font Creator, you should use the button that says "Export for TFT and new GLCD (new library)". That code will work with the advanced GLCD functions.

Peace,
Jim

Sorry, but there is no such buttons in my Font Creator, and just to be sure I've got the latest I just download it and re-installed it again.
My previous version was 1.200, and today version is the same.

There must be something else......

Hmmm that's odd. I have had mine for while but it's still the same version (1.2.0.0). The 'export for TFT and new GLCD' button should be right next to the 'export for GLCD' button like this...




Peace,
Jim

[HyperUniverse]

Thanks for your help Jim.

Indeed I didn't have that button.
But, this was because I was using the program in "window" mode, not full screen.
As soon as I've made it "full screen" there is the button missing, popping where you pointed.

(or at lest you need the program to run in a wide enough window to be able to see that button)!!!

Now I see my big "7" on the screen.
Thanks again for your help Jim.

[Jim Walsh]

Sweet! No problem my friend, I'm glad that you were able to get it working. I have had similar experience with some of my programs. I would be missing parts even when I maximized the window. Turned out it was because I had set Windows to 'magnify mode' in order to make it easy to read stuff on the monitor, which worked great as long as it was all text, but not so much with some other programs.

Peace,
Jim

Hello,
I have tried the custom font using the GLCD Font creator by Mikroe on GLCD 240x128. I have set the font size using the T6963C_Set_Font_Adv() function and writing to it using T6963C_write_char_adv() and T6963C_Write_Text_Adv() functions.
It has been observed that it does not clear the text after writing. Instead it overwrite the new text over the old text.
I have the complete business logic on GLCD 128x64 and now I have to shift it to the 240x128 GLCD.
Please suggest the solution how the previous character or text can be cleared after writing new one.
Thanks in advance.

[filip]

Hi,

There are two ways to do this :
1. Draw a box on the place on the character that you want do delete,
2. Write a string with where you would replace this character with blank space.

Regards,
Filip.
