2.8 inch touchscreen lcd displays arduino unos for sale

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection slot. This TFT display is big (2.8" diagonal) bright and colorful (RGB, 65K colors)! 320x240 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load the provided library - you"ll have it running! Works best with any standard Arduino interface like Arduino UNO, Leonardo, UNO PLUS, NUCLEO, XNUCLEO etc. This shield has on board stand alone touch controller, controlled via SPI only a few pins are used.

This 2.8-inch TFT LCD Resistive Touch Screen for Arduino features a 320x240p hardware resolution. This Arduino LCD Shield is compatible with the SPI communication interface. It is a resistive touch screen with a standalone XPT2046 touch controller. In addition, this TFT LCD features an onboard LCD controller ST7789 embedded driver chip. It is a multicolor RGB touch LCD with 65K bit depth / color levels. The 2.8-inch TFT LCD Arduino Shield also features a Micro SD Slot (the SD Card is NOT included).

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

I had some success with this. By observing the sketches I decided that at least in the BMP sketch that A5 did not seem to be used. I have another Shield called the Dr Dunio that can redirect most of the GPIO pins to another option by use of a jumper. I placed the Dr D shield in my UNO and then placed the LCD shield on top of it. The Dr D board has 16 jumpers that can be in one of two positions. With the jumper in a position marked with a dot the pin effectively goes straight through to the header where the LCD shield is installed. So with all jumpers in the dot positions, the Dr D shield passes all pins straight through. I determined that the jumper on pin A5 could be placed in the dot position, the non dot position and even removed and the LCD sketch worked properly. I then put the Dr D jumper on the non dot position which connects it to a pot on the Dr D shield. I added in a few lines of code which did an analogRead (A5) and printed it out on the Serial Monitor. I could change the pot of the Dr D board and see a corresponding change in the Serial Monitor. All the while the pictures on the LCD screen were acting as before. This leads me to believe I can use A5 for my own purposes. Unfortunately my choices are somewhat limited with only this pin available.
