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
