[solved] The MIOS_GLCD_FONT is corrupted

nsunier · May 4, 2008, 6:00pm

I’m currently writing an application based on the example code provided by TK.

All was working like a charm until today. Sometimes, when I add some code concerning the LCD display the MIOS_GLCD_FONT seems to be corrupted. The other fonts provided in .\modules\glcd_font directory works well.

I’ve two section in the void DISPLAY_Tick(void) function:

display AIN changes
display DIN changes

Here is my function (the DIN part is still under development):

/////////////////////////////////////////////////////////////////////////////
//  This function is called in the mainloop when no temporary message is shown
//  on screen. Print the realtime messages here
/////////////////////////////////////////////////////////////////////////////
void DISPLAY_Tick(void) __wparam
{
	// do nothing if no update has been requested
  if( !app_flags.DISPLAY_UPDATE_REQ )
    return;                  
                             
  // clear request           
  app_flags.DISPLAY_UPDATE_REQ = 0;

	switch (last_ain_func) // pot related display update
  {
    case 1:  // current pot = submaster
      // print pot name
      MIOS_GLCD_FontInit(GLCD_FONT_BIG);
      MIOS_GLCD_GCursorSet(16,0);
      MIOS_LCD_PrintCString(pot_name[last_ain_pin]);
      
      // print pot value
      MIOS_GLCD_GCursorSet(16,4);
      MIOS_LCD_PrintBCD3(cur_pot_values[pot_event_map[last_ain_pin][0]]);
      
      // print pot meter value
      MIOS_GLCD_FontInit(GLCD_FONT_METER_ICONS_V_BIG);
      MIOS_GLCD_GCursorSet(0,0);
      MIOS_LCD_PrintChar(pot_meter[cur_pot_values[pot_event_map[last_ain_pin][0]]][0]);
      
    // set LED
	    if (cur_pot_values[pot_event_map[last_ain_pin][0]]>1)
	    MIOS_DOUT_PinSet(led_map[pot_event_map[last_ain_pin][0]][0], 0x01);
	    else
	    MIOS_DOUT_PinSet(led_map[pot_event_map[last_ain_pin][0]][0], 0x00);
    	
    break;
    
    case 2:  // current pot = grandmaster
      // print pot name
      MIOS_GLCD_FontInit(GLCD_FONT_BIG);
      MIOS_GLCD_GCursorSet(16,0);
      MIOS_LCD_PrintCString(pot_name[last_ain_pin]);
      
      // print pot value
      MIOS_GLCD_GCursorSet(16,4);
      MIOS_LCD_PrintBCD3(cur_pot_values[pot_event_map[last_ain_pin][0]]);
      
      // print pot meter value
      MIOS_GLCD_FontInit(GLCD_FONT_METER_ICONS_V_BIG);
      MIOS_GLCD_GCursorSet(0,0);
      MIOS_LCD_PrintChar(pot_meter[cur_pot_values[pot_event_map[last_ain_pin][0]]][0]);
      
    // set LED
	    if (cur_pot_values[pot_event_map[last_ain_pin][0]]>1)
	    MIOS_DOUT_PinSet(led_map[91][0], 0x01);
	    else
	    MIOS_DOUT_PinSet(led_map[91][0], 0x00);
  
    break;
    	
    default:
    break;
  }
  last_ain_func=0;

  switch (last_din_func) // buton related display update
  {
    case 1:  // current button = flash
      // print pot name
      MIOS_GLCD_FontInit(GLCD_FONT_BIG);
      MIOS_GLCD_GCursorSet(16,0);
      MIOS_LCD_PrintCString(but_name[last_din_pin][0]);

    break;

    default:
    break;
  }
  last_din_func=0;
}

  {"        ","        "},  // not connected 
  };

When I disable the switch(last_ain_func) or switch(last_ain_func) there isn’t any problem. But when I enable both it works but it just like if the MIOS_GLCD_FONT was corrupted: the MIOS is rebooting and the © T.K. aren’t visible (blank display or erratic characters). All the other parts are still working (other fonts, AIN, DIN, DOUT, MIDI send, …). I have to reload the MIOS itself in order to get back the display.

What could be the problem? Too much code inside this function? (I’ve tried to put this portion of code inside the void Tick(void) function: same problem). I’m very lost inside this problem. Any idea is welcome.

EDIT

This problem is not only due to the void DISPLAY_Tick(void) function. When I just add an if statement in the void DIN_NotifyToggle(unsigned char pin, unsigned char pin_value) function it produces the same problem.

Do you think my code is too big and overwrite the memory area used for the MIOS_GLCD_FONT? I’m using a PIC18F452. How can I verify this?

Does your code overwrite the area between 0x7c00..0x7fff?

Or did this ever happen?

Best Regards, Thorsten.

Sorry ??? How can I verify this?

[/tt]

(red marked text is the code area, which contains the graphical default font)

You will also find the allocated addresses in the .lst and .map file

So, which address range is allocated by your application?

Btw.: you can “repair” the graphical default font by uploading MIOS again

So it’s clearly an overwrite!! What should I do? To change my PIC?

I don’t understand very well what you told me about .lst and .map files. Should I post them? Which files exactly? main.lst and project.map?

Best regards,

nsunier

T.K · May 4, 2008, 9:08pm

So it’s clearly an overwrite!! What should I do? To change my PIC?

If you don’t find a way to reduce code size, then yes: just change to a PIC18F4620, it can save you from a lot of additional programming effort

I don’t understand very well what you told me about .lst and .map files. Should I post them?

No - you asked how to verify the allocated memory areas, I proposed three different possibilities to find this out. If the content of main.lst and project.map doesn’t make sense to you, then you rely on the output of MIOS Studio

Best Regards, Thorsten.

nsunier · May 5, 2008, 7:42am

I’ve burned a PIC18F4620 with the bootloader v1.2b; loaded the MIOS.

I’ve a problem to recompile my code for the new processor. I’ve changed in Makefile.orig file the following lines:

PROCESSOR = p18f452 -> PROCESSOR = p18f4620

OBJS = pic18f452.o mios_wrapper.o app_lcd.o main.o -> OBJS = pic18f4620.o mios_wrapper.o app_lcd.o main.o

When I do a make I get this message:

rm -rf _output/*
rm -rf _output
rm -rf *.cod *.map *.lst
rm -rf *.hex
mkdir -p _output

In the Makefile.orig file, there is written: LKR_FILE = $(MIOS_PATH)/etc/lkr/$(PROCESSOR).lkr

In the ./etc/lkr/ directory I can only found the p18f452.lkr file

Is there a file missing?

Best regards,

nsunier

stryd_one · May 5, 2008, 11:29am

http://svnmios.midibox.org/trunk/etc/lkr/

Not sure what you’re using as a skeleton?

T.K · May 5, 2008, 6:04pm

It seems, that you are using an older SDCC version (you can verify this with “sdcc --version”

The latest release is v2.8.0

Yes, and maybe you need to add the p18f4620.lkr file to the etc/lkr directory, if it isn’t in there yet (don’t remember, if it was in your .zip package)

Best Regards, Thorsten.

nsunier · May 5, 2008, 7:22pm

I’ve installed the latest version of SDCC (v2.8.0) instead of the old one (v2.5.0). I’ve added the p18f4620.lkr file to the etc/lkr directory. And I’ve succeeded in compiling the code.

I can add a little bit of code and it still works. But after adding some extra lines, the MIOS Studio writed this message: “Sending block 00007D00-00007DFF” -> corruption of the display font. I can’t understand!! In the Microchip description there is written that PIC18F4620 has twice the memory of the PIC18F452. And I haven’t add twice the initial code!?

PIC18F452

Flash: 32 Kbytes

RAM: 1,536

EEPROM: 256 bytes

PIC18F4620

Flash: 64 Kbytes

RAM: 3,968

EEPROM: 1024 bytes

What’s going wrong?

Best regards,

nsunier

T.K · May 5, 2008, 7:41pm

The default default font location is always the same. If your application overwrites this location, the font has to be included into the project, and initialized from there.

Under

http://svnmios.midibox.org/trunk/modules/glcd_font/

you will find a new font: GLCD_FONT_NORMAL

This is exactly the MIOS font, which you now have to include into your project

In order to update, download following files and copy them into the modules/glcd_font directory:

glcd_font.h, glcd_font.mk, glcd_font_normal.asm, glcd_font_normal.inc, glcd_font_normal.xpm

Thereafter add “glcd_font_normal.o” to the OBJS variable of your Makefile

Thereafter initialize this font in Init() with:

MIOS_GLCD_FontInit(GLCD_FONT_NORMAL);

instead of

MIOS_GLCD_FontInit(MIOS_GLCD_FONT);

In general, you now always have to use GLCD_FONT_NORMAL instead of MIOS_GLCD_FONT - so, probably you also need to change this at other places in your code.

Best Regards, Thorsten.

nsunier · May 5, 2008, 7:46pm

Two questions:

If I do that, what will be the new max available upper block address?

Best regards,

nsunier

T.K · May 5, 2008, 7:53pm

I cannot say exactly, what will happen with my copyright message. The new font should be selected before it is print… or do you see a different text?

Did you already try this out, or was it just a question?

Now, it doesn’t matter anymore where the font is located (it will be located by the linker automatically…)

The new upper address is 0xffff.

Best Regards, Thorsten.

nsunier · May 5, 2008, 8:05pm

It’s just a question.

I’ve added the new font (and disabled all unused ones: like I was already doing). And I get this message:

Seems that there is an error in the .lkr script.

Does it work, when you replace:

CODEPAGE NAME=page START=0x3000 END=0x7FFF

by

CODEPAGE NAME=page START=0x3000 END=0xFFFF

Best Regards, Thorsten.

nsunier · May 5, 2008, 8:25pm

It works now!

But… The system font used for your copyright message and for the rebooting message is corrupted. How can I modify the MIOS in order it uses the new font?

Best regards,

nsunier

T.K · May 5, 2008, 8:30pm

Fine!

It’s strange, that the wrong font is used for the copyright message, according to the code it should work. Are you sure?

For the reboot message it’s clear, but there is no solution, as the font is not statically assigned anymore, but under control of your application. However, since the message is only displayed after code upload, and not under normal circumstances, it should be acceptable, no?

Best Regards, Thorsten.

nsunier · May 5, 2008, 8:37pm

The GLCD_FONT_NORMAL font is initialized in the void DISPLAY_Init(void) function. When do you display your copyright message? Before when this function is called?

For the reboot message, yes it’s acceptable.

Best regards,

nsunier

EDIT

Oups! I’ve read too quicly your previous answer. If I put the initialization in the Init() function, it works!

T.K · May 5, 2008, 8:57pm

Alright, thats what I expect.

Init() will be called before the copyright message (and before the LCD initialisation), whereas DISPLAY_Init() will be called after the copyright message

Best Regards, Thorsten.
