Hello
Just a feedback after 3 days debuging my problem and having a white screen all the time.
I used the wiring of Post 93 but with a 5V Pro Mini. In oder to gain the 3.3V I used a L78L33 voltage converter connected on the 5V pin. The wiring of Post 93 didn't work as long I had the VCC of the TFT on 3.3V (white screen flickering with LED13 during graphictest.ino). After I connected VCC of the TFT to the 5V pin on the Pro Mini....voila!
The empty InputB on the CD4050 was not necessary to put on GND to make it work.
I hope this info is helpful for others dealing with the same struggle as I did.
PS: I used oli's ucglib. HWSPI was faster than SWSPI.
