When I instead connect my 3.3V regulated supply, I have a white screen but none leds on the Arduino. On Arduino Uno/Duemilanove/328-based, thats Digital 13. Start by connecting the power pins 3-5V Vin connects to the Arduino 5V pin GND connects to Arduino ground CLK connects to SPI clock. Question : when I connect my ftdi, the Arduino pro mini has a red light and a green one. Wiring Wiring up the display in SPI mode is much easier than 8-bit mode since there's way fewer wires. When I connect my ftdi I have this on the serial tracker :Īdafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC,TFT_RST) I tried to do something better (easy lol) with the wiring. (I suspect the shopkeeper will become silent) All shopkeepers will lie through their teeth.ĭemand a FULL refund. Of course it will NOT work without resistors. No, it is not difficult to wire resistors or level shifters. Yes, of course a 3.3V display works perfectly at 3.3V. There are no level shifting components on that pcb. The photos in the link show a regular Red 3.3V board. So, rather than have to use level shifters of resistor dividers, I made the whole project run at 3.3v. I chose this board because, although the seller of this display claims that it will work at both 5v and 3.3v, the majority of these display will not. I used a 3.3V 8MHz Arduino Pro Mini to drive the display - also sourced very cheaply on Ebay. The first phase of the is project is to try out the colour display. 'graphicstest' example, which is in the ILI9341 library examples folder, and downloaded "Adafruit-GFX-Library" and Adafruit_ILI9341.Īnd this data in the Serial Monitor Output:įor this project I used a 2.4" 240 x 320 TFT Touch screen with SD Card holder the I got on Ebay from this seller for £2.99. I used the same connections and same programm as described here, This is my connection to the board, without any resistors.
