[Feature request] UTouch & UTFT_Buttons support? #13

Closed information-security closed 6 years ago

information-security commented 7 years ago

Hi,

when using UTFT library we can use UTouch and UTFT_Buttons libraries which are very useful. Can you please implement similar libraries which will work with yours?

Thanks in advance

The Mcufriend Uno Shields have a resistive Touch Screen. You use the "TouchScreen,h" library from Adafruit. I suggest that you edit it to use a sensible value for NUMSAMPLES.

I put a new version of the TouchScreen Calibration sketch in the examples folder yesterday. The regular Adafruit_GFX_Button class comes with the Adafruit_GFX library. MCUFRIEND_kbv programs work just fine with any of the GFX features.

If you are using a Mcufriend Mega Shield as a SPECIAL, these have an XPT2046 Touch Controller chip. You can use the UTouch or URTouch library or any library that supports bit-banging a XPT2046.

David.
