[Question]Maximum file size in COF application ?

jhpark

I got new device, DMG10600F101_01W. And I found it's COF and it has the different spec (for programming) from DMG10600T101_A5WTR.

Especially, it should use 23.icl file to save the image files (background, icon or else).
And document say each file has limited section(?) in 256 kbytes (page.12),
does this mean that 23.icl file also has the limitation of max file size in 256 KB ???

YES   it is
DMG10600F101_ The flash size of 01W is 16M, and a font library is 256KB. The available space is 0-63, totaling 64 font libraries

DMG10600F101_01W
The Naming convention of this model is the same as your previous screen, but its background image is factory named 32

Ops, I  didn't check my deivce's flash memory size !! Yes it's 16M.
(I thought COF device should have 8M..)

Thanks you so much lijiayan and wangyuxiang, I almost forgot to check !

I guess "font library" is also adopted to 32.ICL too and
32.ICL's filesize should be under 256KB ?

lijiayan

Of course, each font space is 256KB, and the difference is whether the flash size is 8M or 16M

If so, do I have to keep the file size of 32.ICL to under 256 KB ?
Well, normally, 32.ICL's file size is big as it has many larger image files...

One ID is 256K, which depends on how much memory 32ICL occupies; If the memory size of 32.ICL is 257K, then it takes up 32.33 ID numbers, and the next one is the ID number starting from 34.

Thanks for your information !
I see that the numbering will be happened.

Then, do I have to care it  ? or <system> will handle the numbering automatically ?

The file number needs to be set by yourself, and it is important to ensure that each font does not conflict.

Sure I know I must set the background image file to 32.ICL,
but what I want to get the confirmation is that :  what if my 32.ICL file size exceed the 256KB ?

For example, my 32.ICL's file size is 500KB,
do I have to split it to 32, 33.ICL files by myself ? 32.ICL(256KB) and 33.ICL(244KB).
Or I can just put 32.ICL and system split it 32 and 33.ICL files internally ?
