The table below shows the 1.8 TFT wiring to Arduino UNO. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! You can get the 1.8 TFT display for approximately $3 – check prices on Maker Advisor. To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later. This module uses SPI communication – see the wiring below. The following figure shows the screen front and back view. The display can load images from an SD card – it has an SD card slot at the back. The 1.8 TFT is a colorful display with 128 x 160 color pixels.

You’ll learn how to wire the display, write text, draw shapes and display images on the screen. Serial.In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. Serial.print(F("Rounded rects (outline) ")) Serial.println(testFilledCircles(10, MAGENTA)) Serial.println(testFilledRects(YELLOW, MAGENTA)) Serial.print(F("Rectangles (outline) ")) Serial.println(testFastLines(RED, BLUE)) Serial.println(F("Benchmark Time (microseconds)")) Serial.println(F("matches the tutorial.")) Serial.println(F("Also if using the breakout, double-check that all wiring")) Serial.println(F("If using the breakout board, it should NOT be #defined!"))

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

Here is the code i used for testing, it uses the same library, Hope that helps you. if your still having trouble, try removing the shield and watch each pin as you insert it to make sure they are all inserted in the correct pins, LCD_02 should be in Dig pin 2. Im new to Arduino myself but i do have the same screen which works perfect,your problem is probably that the TFT shield is shorting off the top off the arduino usb put something non conductive there and reset. Tft.drawRect(100, 100, BOXSIZE, BOXSIZE, WHITE) Īs you can see, the background is black, and a box is being drawn behind these colored bars. here is my code: #include Īdafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET) Right now all i am trying to do is fill the screen and draw a box. The problem that I am having is that there are all of these colored lines being drawn on the screen after a reset and initialization. I am having troubling using this board with my Arduino Uno and I was hoping someone could help. I am hoping that someone is familiar with the 2.4" TFT LCD Display board from MCUFriend.
