I have tried a range of ported library's for the ILI9341 SPI display and so far the Adafuit GFX ported version with additional fonts is the best in terms of speed and functionality. This works in conjunction with the Adafruit ILI9341 library.

The new UTFT library is pretty cool and allows the drawing of color images but is slow in comparison. I have even ensured that the HW SPI is running at 40 MHz.

The only thing I can't seem to do is to draw color images converted with Imageconvert565.

Does anyone have a code snip or modified library that provides this flexibility? would be great.

Cheers

Dans

Hi @chnyc,

I am going to look in to this again as it fell on completely deaf ears in this forum. The aim is to draw color icons on a IlI9341 display. I have the new Adafruit GFX lib with extended fonts. I am pretty certain the color push routine needs to be tweaked inline with a custom routine to draw color images.

Been tied up with other priorities but will get back to this soon.

Regards
