Loading custom font

[semir-t]

Is there any example on how to load the custom font using this library ?

No, I haven't implemented this feature. Although it should be possible if you're willing to dig into the FT81x's documentation.

Yes, I am already trying to do that but without any luck.

I am guided by the following application note and I managed to generate the data that needs to be loaded. This data is loaded by following code:

ft81x.writeGRAM(1000,148,SAMApp_ShowCustomFont_MetricBlock);
ft81x.writeGRAM(1000 + 148,5510,SAMApp_ShowCustomFont_FontBmpData);
ft81x.beginDisplayList();
ft81x.clear(WHITE);
ft81x.clear(FT81x_COLOR_RGB(255,255,255));
ft81x.drawText(240, 230, 34, FT81x_COLOR_RGB(0,0,0), FT81x_OPT_CENTER, "Font1\0"); 
ft81x.sendCommand(BITMAP_HANDLE(6));
/* ft81x.sendCommand(BITMAP_SOURCE(1000)); */
/* ft81x.sendCommand(BITMAP_SOURCE(1090)); */
/* ft81x.sendCommand(BITMAP_SOURCE(-508)); */
ft81x.sendCommand(BITMAP_SOURCE(-708));
ft81x.sendCommand(BITMAP_LAYOUT(FT_L1,2,29));
ft81x.sendCommand(BITMAP_SIZE(FT_NEAREST,FT_BORDER,FT_BORDER,16,29));

ft81x.sendCommand(0xFFFFFF2BUL);
ft81x.sendCommand(6);
ft81x.sendCommand(FT81x_RAM_G + 1000);
ft81x.sendCommand(0);
}
ft81x.drawText(240, 280, 6, FT81x_COLOR_RGB(0,0,0), FT81x_OPT_CENTER, "Font2\0");
ft81x.swapScreen();`

`
But I only get white screen in a place where text should be and I am running out of ideas. :/

It seems to me that your approach is correct. I haven't tried this myself yet and I'd need to consult the documentation to verify your code, so I can't tell you much more right now.

Ok, I will continue to work on it and will write comment here if I manage to fix it.
