eglib's Issues

Create Arduino package

Normalize RGB > display color depth

Currently display drivers with color depth < 24bpp quantize to their own lower bit depth using their own logic. Let's make this logic common across all displays so that users have a consistent interface, eg, #FFFFFF is always white on BW displays).

Add avr-libc HAL driver

Documentation

Add text rotation support

0 degrees
90 degrees

Is this library ready for use?

I found your st7789 related submission in ucglib. and I transplanted it to the nodemcu board. But I found that there is no image-related api, this library is to add related features?
