adafruit 2.8 tft lcd breakout board free sample

"In the TFTLCD Library folder, you will need to edit TFTLCD.h. On about line 12, you will see "#define USE_ADAFRUIT_SHIELD_PINOUT". Comment out this line and save the file."

I have done this, saved the file, reopened arduino.exe, loaded the graphicstest example that comes with the TFT LCD library and tried to verify/compile it, but here I get errors:

"Start at the end of the TFT (other side than the power pins) and in order connect the pins to digital 7 thru 2. If you"re using a mega, connect the TFT Data Pins #0-7 to Mega pins #22-29, in that order. Those Mega pins are on the "double" header.

Connect the seventh pin RST (Reset) to the Arduino Reset line. This will reset the panel when the Arduino is Reset. You can also use a digital pin for the LCD reset but this will save us a pin."

The code in the library is optimized. It makes use of port-level I/O for speed. Since the port/pin mappings vary between the different processors and boards, the code is very board specific.

When I run either the graphicstest or the tftbmp example, the identification part works now, but the screen doesnt display anything other than the backlight, and a quick flicker (<20ms or so) at the exact moment something is drawn to the screen.

I have browsed 70 pages of forum searchresults on "2.8 TFT", but pretty much everyone who had this issue has gotten an offer for a replacement, so I am unsure how to move forward from here.

I do not think that the code used for Teensy support in pin_magic.h can/will be optimized any further except maybe change the pins to a more grouped section of pins, mine are all over the board now...

The 2.8″ TFT LCD with Touchscreen Breakout Board with a MicroSD Socket and an ILI9341 controller display can be used to add a graphical user interface (GUI) to a project. The TFT (thin-film transistor) LCD (liquid crystal display) has a resolution of 240×320 pixels, which allows it to display detailed images and text. The touchscreen feature allows users to interact with the display by touching the screen. The MicroSD socket can be used to store and access data from a MicroSD card. The ILI9341 controller is responsible for driving the display and handling touch input. This breakout board can be used with a microcontroller to create a GUI for a project or application.

ER-TFTM035-6 is 320x480 dots 3.5" color tft lcd module display with ILI9488 controller and breakout board,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO,ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.

It supports 8080 8-bit /9-bit/16-bit /18-bit parallel ,3-wire,4-wire serial spi interface.Built-in microSD card slot, optional 3.5" 4-wire resistive touch panel with controller XPT2046 and capacitive touch panel with controller FT6236, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover . It"s optional for font chip, flash chip and microsd card. We offer two types connection,one is pin header and the another is ZIF connector with flat cable mounting on board by default and suggested. Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.5"TFT Touch Shield with Libraries, EXxamples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

I am trying to follow the instructions provided by the vendor https://learn.adafruit.com/2-8-tft-touch-shield/touchscreen-paint-example to no avail. Specifically:
