Discussion - EVE / accessing custom font Glyphs in Flash

« on: January 13, 2021, 07:54:01 PM »

Currently I am setting the “start_of_Graphic_data” (p + 32), to the location of where the glyph file is in RAM.

local Xfont = assetLoader.ImageInfo[xfont].index;
local Glyph = assetLoader.ImageInfo[glyph].index;
MCU_WriteMem32(Xfont + 32, Glyph);

For a glyph stored in Flash ([0x02F000 -> 0x057000]) for instance,
How would I compute the flash address to store in the “start_of_Graphic_data” ?
Is there anything else I need to modify in the xfont (Font Metrics Block)?

Discussion - EVE / BT Flash questions...

« on: December 28, 2020, 02:55:46 PM »

When accessing the BT Flash, do we use the address 0x800000 for access/reference once its been initialized or use a relative address (0x00000) ?
Is the BT Flash persistent, or does it need to be initialized after every GPU reset?

Discussion - EVE / UTF 8 characters with Keys widget

« on: October 09, 2020, 02:48:01 PM »

Has anyone tried using the Keys, CMD_KEYS, widget with custom (UTF8) characters?
I am able to display international characters (Ä ö Ü ü ß â é è î ô) in Text and Button, but not in the Keys widget. BT81X Is there anything special needed to be done for the Keys widget?
