For the Arduino Mega, use digital pins 22 through 29 D1 connects to digital pin 9 NOT in order!) D0 connects to digital pin 8 (Notice these are For the Arduino Uno, Duemilanove, Diecimila, etc.: When using the BREAKOUT BOARD only, use these 8 data lines to the LCD: #define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin #define LCD_RD A0 // LCD Read goes to Analog 0 #define LCD_WR A1 // LCD Write goes to Analog 1 #define LCD_CD A2 // Command/Data goes to Analog 2 #define LCD_CS A3 // Chip Select goes to Analog 3 double up the pins with the touch screen (see the TFT paint example). analog pins.but we'll use the analog pins as this allows us to The control pins for the LCD can be assigned to any digital or SEE RELEVANT COMMENTS IN Adafruit_TFTLCD.h FOR SETUP. CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD. Image 1920×2560 593 KB // IMPORTANT: Adafruit_TFTLCD LIBRARY MUST BE SPECIFICALLY I think I have all the wiring done correctly. The output shows that it does not identify the HX8357 display chip properly and the display does light up but it remains blank. If using the breakout board, it should NOT be #defined!Īlso if using the breakout, double-check that all wiring Should appear in the library header (Adafruit_TFT.h). If using the Adafruit 2.8" TFT Arduino shield, the line: Using Adafruit 3.5" TFT Breakout Board Pinout The graphicstest.ino was adjusted to indicate a 3.5” board and when run it produces the following output.The library file Adafruit_TFTLCD.cpp has been modified to adjust the size to 320 x 480.ayFullFile("/track001.I have successfully used the Adafruit 3.5 TFT display in SPI mode on UNO, Mega, and Teensy boards but now I am having trouble getting it to work on the Arduino Mega board in parallel mode.

I am hitting a roadblock trying to understand SPI master slave configurations. I for the life of me cannot figure out how to either output their respective signals on two pins or share one somehow. Hello! I am working on a project that has two devices each with their own CLK pins.
