Hello Fernando, I am simply testing with jumper wires some new devices, stamps etc, I just try to test pcf8575 first and when uncommenting to enable use_pcf8575, the TFT does not seem to initialise?
Is this something you have heard before?
It is curious as I see no reason why this should happen..
This is on fresh blank version on the sainsmart 7.0" LCD and the elekfreaks 2.2 tft shield with white colour.
Kind Regards
Jay
PS. I did try some searching to find a reference but there was nothing relating to this..
