pippoc you did not understand anything about how to use the "Adafruit_ILI9341". Your video is totally wrong. 1) if you use the "SPI software": Adafruit_ILI9341 (TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO) the disply will be slow. 2) if you use the "Hardware SPI" the display will be very fast. To do this you can use the constructor: #define TFT_DC 9 #define TFT_CS 10 Adafruit_ILI9341 (TFT_CS, TFT_DC) and connect TFT_RST to 3.3v or use the manufacturer Adafruit_ILI9341 (TFT_CS, TFT_DC, TFT_RST) e #define TFT_RST 8 (for example). Your display should be slow, not because of the resistance but because you use the libraries badly.
