Color 320x240 TFT Display, ILI9341 Controller Chip
This 320x240 color TFT display is recommended for use with Teensy 3.2, for high resolution color graphics. It can be used with the Adafruit_ILI9341 library or Optimized ILI9341 library. ILI9341_t3 supports large high-res fonts. A library of additional fonts is available, as well as huge collection of Google fonts. There's also an alternate https://forum.pjrc.com/threads/39804-ILI9341-font-builder, in addition to ttf_to_ili9341.pl. Two alternate optimized libraries are available, from Frank B and KurtE.
Connections
Caution: Use only 3.3V signals with this display. CS, D/C, SDI, SCK are NOT 5 volt tolerant. We recommend using this display only with Teensy LC & 3.x. It should not be used with 5V boards like Teensy 2.0 and Arduino Uno. We do not recommend using the SD card socket on this display. It does not work, but this hardware modification may be able to get it working. Usage With Audio Board ConnectionsTo use the ILI9341 display with the Audio Board, connect the signals using the alternate pins shown above.For use with the Teensy 3.2 optimized library, use this 6 pin constructor code.
// For optimized ILI9341_t3 library #define TFT_DC 20 #define TFT_CS 21 #define TFT_RST 255 // 255 = unused, connect to 3.3V #define TFT_MOSI 7 #define TFT_SCLK 14 #define TFT_MISO 12 ILI9341_t3 tft = ILI9341_t3(TFT_CS, TFT_DC, TFT_RST, TFT_MOSI, TFT_SCLK, TFT_MISO); For use with Adafruit's original ILI9341 library, in setup() before calling TFT.begin(), use SPI.setMOSI(7) and SPI.setSCK(14) to configure the SPI library for these alternate pins.
// For Adafruit's ILI9341 library #define TFT_DC 20 #define TFT_CS 21 Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC); void setup() { SPI.setMOSI(7); SPI.setSCK(14); tft.begin(); DimensionsThe active screen area is approximately 2.8 inches diagonal.
High-Res FontsMany additional fonts are available in this library of additional fonts and Frank's huge collection of Google fonts.All fonts are available in these sizes: 8, 9, 10, 11, 12, 13, 14, 16, 18, 20, 24, 28, 32, 40, 48, 60, 72, 96 These images are only a small sample of the many fonts available:
