14 pin 2.8 tft lcd pin out supplier

This 2.8″ TFT LCD is a full color display with a resolution of 240 x 320 pixels or 320 x 240 pixels depending on how it is oriented.  It uses the ILI9341 controller with SPI interface.  It also includes a resistive touchscreen with built-in XPT2046 controller.

The module power comes in on the Vcc pin.  The module includes an on-board 3.3V regulator, so the module should normally be operated off of 3.6 to 5.5V power on this pin to feed the regulator.  Current is typically 55-60mA

These modules are breadboard friendly with a 14-pin header on the back that can be inserted into a solderless breadboard or a 14-pin female connector can be used to connect to it if the display is to be mounted.  The display is mounted on a stiff PCB that provides good support, but be sure to press on the header pins or PCB when applying pressure to insert them into a breadboard and not press on the glass to avoid possible damage.

Though these displays can seem to be a bit intimidating to use at first, just follow these steps to get up and running fairly easily.  The pin labeling is on the back only, so we have pictures with the pins labeled on both the front and back to make life a little easier.

I’m also using the Teensy 4.1 because it is currently the fastest Arduino compatible board (600MHz 32-bit vs Uno 16MHz 16-bit) and this example application of calculating Mandelbrot fractals and updating the LCD can take a long time on an Uno (77-105 seconds) and only takes about 1.25 seconds on the Teensy 4.1.  If using a 3.3V Arduino like a Due, hookup will basically be the same.

Connect the SPI and control lines for the display.  In our example we are using hardware SPI as it gives the best performance.   The SPI pin location will depend on the MCU you are using.

After drawing the first screen, it waits until the touchscreen is touched and then it zooms in slightly and redraws the screen.  It also reports the touch location information out to the Serial Monitor window and also reports how long it took to calculate that screen.  If you want to evolve the program as an exercise, it would be interesting to use the touch coordinates to center the new zoom.

My first post back from hiatus talked about how I was getting into hardware components and programming them. Although I’ve had both hardware and software experience, the experience of producing home-grown hardware/software solutions is something new to me. It is very fascinating though and I am absolutely gitty about it… just ask my coworkers. I can’t shut up about it.

As you may have read in the previous post, after careful consideration I ordered up a bunch of hardware. For the sake of this article, however, only two items will be important from that list. They are the Seeeduino Mega 2560 ADK dev board and the 2.8″ TFT Touch Shield. The problem I was experiencing was that when I plugged the 2.8″ TFT Touch Shield (“shield”) into the Seeeduino Mega 2560 ADK (“Seeeduino”), all I got was a white background with the backlight on. There was nothing else going on. I tried just about every library under the sun, every example, my own code, searching Google for solutions, etc. I saw that lots of folks were having this problem, but no one had any solutions. So, I eventually posted the problem to the Seeduino forums.

I didn’t get any replies, only more people with the same issue getting in on the action. Fortunately someone at Seeeduino took pitty on me and emailed me about it. After a couple of emails back and forth it turns out the fix is quite easy. It has to do with the Mega 2560 pinout being different than the standard arduino/seeeduino. As you can see in the image below, the regular Arduino (Uno for instance) has 14 Digital I/O pins and 6 analog input pins whereas the Mega 2560 has 54 digital I/O pins and 16 analog input pins.

Due to this difference the screen has to use different pins. Unfortunately the example sketches in the TFT library don’t tell you that you have to change anything so what you wind up with on the Mega 2560 boards is the TFT screen with a blank white background and the backlight on.

Congratulations! You’ve successfully fixed the TFT library so that you can use it with a Arduino or Seeeduino Mega 2560 or Mega 2560 ADK! On my board I tested it out and everything was great after that! Try the drawCircle sketch from the library examples once you fix this.
