GFX library fonts

[Stas]

I want to use in my project tft 1.8 display with st7735 controller. I used the standard GFX example from SDK 14.1 and everything is working fine, but the picture is incorrectly displayed and I found only two fonts. Can I find additional fonts for the GFX library somewhere?

I use the dot factory to generate additional fonts for my display. They have a good amount of fonts available. I never used the GFX example from nordic though so you might have to do some slight alterations to make the generated output compatible. www.eran.io/.../

Thanks. Second problem for us is our display update very slow (without break image) with gfx example (maybe 300-500ms). We suppose the problem with gfx example. Is it correct that we have to clear display before send to it new info. And Im not telling now about images, just primitive object: circle, line, letters. Could you share your code for use nrf52 + st7735 display
