Is there a maximum number of custom fonts?

[papatrexasgre]

Hello all. Like the subject suggests, is it safe to assume that there is a maximum of 6 custom fonts you can load?

I am currently loading 22 fonts in to 22 different fontVariables, but only the first 6 seem to actually load. Commenting out the first 6 and loading the remaining again gives me 7,8,9,10,11,12 fonts and not the rest. When I say "gives me" I mean that I have a simple routine that ...

.up to arialBold10
.
.
gfx_Cls();
lcdString(1,1, 1, 1, WHITE,arialBold50,"aBold50","  ");
pause(1500);
gfx_Cls();
lcdString(1,1, 1, 1, WHITE,arialBold60,"aBold60","  ");
pause(1500);
gfx_Cls();
lcdString(1,1, 1, 1, WHITE,arialBold71,"aBold71","  ");
pause(1500);
gfx_Cls();
lcdString(1,1, 1, 1, WHITE,arialBold80,"aBold80","  ");
pause(1500);
gfx_Cls();
.
.
.up to arial91

after the first 6 fonts the remaining appear as if I am using the built in FONT1 or FONT2 not sure.
I am loading the fonts like this:

 /*
    arialBold10 := file_LoadImageControl("Op12.da1", "Op12.gc1", 1);
    arialBold14 := file_LoadImageControl("Op12.da2", "Op12.gc2", 1);
    arialBold18 := file_LoadImageControl("Op12.da3", "Op12.gc3", 1);
    arialBold22 := file_LoadImageControl("Op12.da4", "Op12.gc4", 1);
    arialBold26 := file_LoadImageControl("Op12.da5", "Op12.gc5", 1);
    arialBold36 := file_LoadImageControl("Op12.da6", "Op12.gc6", 1);
    */
    arialBold50 := file_LoadImageControl("Op12.da7", "Op12.gc7", 1);
    arialBold60 := file_LoadImageControl("Op12.da8", "Op12.gc8", 1);
    arialBold71 := file_LoadImageControl("Op12.da9", "Op12.gc9", 1);
    arialBold80 := file_LoadImageControl("Op12.d10", "Op12.g10", 1);
    //arialBold91 := file_LoadImageControl("Op12.d11", "Op12.g11", 1);

    arial10 := file_LoadImageControl("Op12.d12", "Op12.g12", 1);
    arial14 := file_LoadImageControl("Op12.d13", "Op12.g13", 1);
    arial18 := file_LoadImageControl("Op12.d14", "Op12.g14", 1);
    arial22 := file_LoadImageControl("Op12.d15", "Op12.g15", 1);
    arial26 := file_LoadImageControl("Op12.d16", "Op12.g16", 1);
    arial36 := file_LoadImageControl("Op12.d17", "Op12.g17", 1);
    arial50 := file_LoadImageControl("Op12.d18", "Op12.g18", 1);
    arial60 := file_LoadImageControl("Op12.d19", "Op12.g19", 1);
    arial71 := file_LoadImageControl("Op12.d20", "Op12.g20", 1);
    arial80 := file_LoadImageControl("Op12.d21", "Op12.g21", 1);
    arial91 := file_LoadImageControl("Op12.d22", "Op12.g22", 1);

you can see above what I mean with "commenting out".
based on the above loading I will see 50,60,71,80,10 and 14 properly and the rest with FONT1.

Thank you for reading me.

I suspect you are running out of RAM, check that the handle is not 0 after loading the image control.

Is your program running from RAM or Flash?

Check out this app note to find out how to run the program from Flash http://www.4dsystems.com.au/appnote/4D-AN-00039/

Thank you for the quick reply.

This is the output I get while programming:

No Errors, code size = 7282 bytes out of 14400 total
Initial RAM size = 1494 bytes out of 14400 total
Program will run from ram so total initial RAM size = 8776 bytes out of 14400 total
Download to RAM successful.

But loading the program to flash yields the exact same result.

Read the app note, there's more to it than just downloading to flash

hmmmm now I see. OK since I will be using a parent/child scheme and since there is not a limitation when it comes to the number of fonts, I will try to manage the memory better. Thanks for once more for showing me the way
