mcufriend 2.8 tft lcd shield pricelist

I have bought "MCUFRIEND" 2.8 tft touch lcd and controller printed on it shows "ILI9338". Example given in this library are not working except for the basic one and it don"t even work with touch examples. After searching on google found out that "MCUFRIEND_kbv" library for debug. When i run "diagnose_tft_support" it shows following output. Also added "Read reg" after first output. Please Help !!!

Edit: Removed SdFatSoftSpi from the showBMP_not_Uno.ino example, no need for Software SPI due the fact that this shield uses the hardwired SPI pins from the Mega2560 (MISO = 50, MOSI = 51, SCK = 52) and does not share them.

It has the XPT2046 touchsceen controller chip on it (top-right) but has voltage regulator AMS1117 (down-left) missing, this seemed not to be a problem to get the shield fully working.

When using the arkejan/UTFT library (other UTFT libraries must be (temporarly) removed from the Arduino IDE libraries folder), you invoke the screen with:

SD card works and uses HW pins with the greiman/SdFat library (but you need to edit the SD_CS in the showBMP_not_Uno.ino file (in the example folder of the MCUFRIEND_kbv library) from SD_CS 10 to SD_CS 53)

I have attached the URTouch & MCUFRIEND_kbv libraries they are already edited and in the examples folder are only the ones that worked for me. If you need more examples, DL the libraries from their Github repositories and edit them yourself.

This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 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 up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino UNO. Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, another pin for the SPI touchscreen controller and another pin for uSD card if you want to read images off of it.

Displaying a custom image or graphic on a LCD display is a very useful task as displays are now a premium way of providing feedback to users on any project. With this functionality, we can build projects that display our own logo, or display images that help users better understand a particular task the project is performing, providing an all-round improved User Experience (UX) for your Arduino or ESP8266 based project. Today’s tutorial will focus on how you can display graphics on most Arduino compatible displays.

The procedure described in this tutorial works with all color displays supported by Adafruit’s GFX library and also works for displays supported by the TFTLCD library from Adafruit with little modification. Some of the displays on which this procedure works include:

For this tutorial, we will use the 2.8″ ILI9325 TFT Display which offers a resolution of 320 x 340 pixels and we will display a bitmap image of a car.

To demonstrate how things work, we will use the 2.8″ TFT Display. The 2.8″ TFT display comes as a shield which plugs directly into the Arduino UNO as shown in the image below.

Not all Arduino displays are available as shields, so when working with any of them, connect the display as you would when displaying text (we recommend following the detailed tutorial for the display type you use of the above list). This means no special connection is required to display graphics.

Image2Code is an easy-to-use, small Java utility to convert images into a byte array that can be used as a bitmap on displays that are compatible with the Adafruit-GFX or Adafruit TFTLCD (with little modification) library.

To reduce the amount of code, and stress involved in displaying the graphics, we will use two wonderful libraries; The GFX library and the TFTLCD library from Adafruit.

As usual, we start writing the sketch by including the libraries required. For this procedure, we will use the TFTLCD library alone, since we are assuming you are using a display that is not supported by the GFX library.

The last section of the code is the drawBitmap function itself, as earlier mentioned, to use the drawbitmap() function with the Adafruit TFTLCD library, we need to copy the function’s code and paste into the Arduino sketch.
