Arduino Due and 2.2" TFT display with ILI9341 driver

   I recently purchased an Arduino Due development board to control 2.2" TFT color graphic display with ILI9341 driver.
   First, I use Arduino Uno then I use Arduino Mega for control this display. Between Arduino board (Uno or Mega) I use CD4050 for convert voltage level, because Uno and mega works with 5V logical level and display with ILI9341 driver works with 3.3V.
   After several attempts I chose ucglib library because is like u8glb library, that I used it at monochrome Nokia mobile displays (like Nokia 3310 display with 84x48 resolution using PCD8544 driver or Nokia 3410 display with 95x64 resolution using PCF8812 driver 3410) or at monochrome display with 128x64 resolution using ST7920 driver.
   I tested with very good results the ucglib library with Arduino Uno & Due for control the colour graphic display with 320x240 resolution using ILI9341 driver and I write few article in roumanian language, who is my native language.
   Also, I write an article in roumanian language with Arduino Due who control the colour graphic display with 320x240 resolution using ILI9341 driver: Arduino Due si afisajul QVGA de 2,2" (5,6cm) comandat de ILI9341.
   Now, I make a summary of that article for interested people...
   Arduino Due is more powerfull then other Arduino boards, becouse runs at 3.3V (maximum tolerate voltage at input or output pins is 3.3V).
   Using informations from article named How to Connect a ILI9341 Display I connect directly pins from Arduino Due and display, like in this picture:
   In my case, schematic is:
   First, I made a weather station with DTH11 sensor for humidity and BMP180 for pressure and temperature, schematic is:
   Then, I simplified the sketch for using just DHT11 sensor for humidity and temperature:
   Practical, wirred is:
   My original sketck for full weather station with BMP180 and DHT11 is:

   I made two movies for understand better what is on display:
- weather station with Arduino Due on ILI9341 2.2" TFT display
   Information are displayed in the roumanian language, but you may change easy...
   For upload sketch for Arduino Due must update Arduino IDE software; now current version is Arduino IDE 1.5.7. BETA. 

   I wait with interest your views and comments!!!

    The Fix for aaa:52: error: 'ucg_font_ncenR14r' was not declared in this scope

    ucg.setFont(ucg_font_ncenR14r);

    CHANGE ucg.setFont(ucg_font_ncenR14r); TO ucg.setFont(ucg_font_ncenR14_tr)
    (See https://github.com/olikraus/ucglib/wiki/reference#migration-from-v101-to-v102) Rename Fonts r changed to _tr.

    Good luck,

    Try changing ucg.setFont(ucg_font_courB24); TO ucg.setFont(ucg_font_courB24_tf);
    I do not know if this works as I have not tried nor verified it.
