I need a bit smaller and less power hungry unit for my next project, so i ordered up the 3.5 inch, 480x320 display (and sheild) that uses the ILI9488 driver with the CAP touch option.

ER-TFTM035-6-4123 is 3.5 inch tft lcd display with adaptor board,ILI9488 arduino shield,examples,library.Optional touch panel,arduino mega2560.due board.

The example code compiles and loads just fine on the DUE, however i simply cannot get the TFT to work. The CAP touch seems to work fine, and reports touches to the serial terminal, but the screen remains white no matter what.

The included example uses the UTFT library, and, as I have yet to find a tutorial on using the library, i"ve just dug into the examples and the library .H files to try and sort out how to use it. As near as i can tell, the UTFT library supports many different typed of displays and SPI/parallel modes. so to initialize the display you put something like

So I set about checking the wiring diagram for both the shield and the display module, double checking the jumpers and trying to sort out the various pins."

As near as i can tell, both the display module and the shield are set up for the 16 bit parallel interface, but where it gets confusing is the shield schem doesn"t look like it matches up with the example code. for starters, the shield jumpers are not labeled like they are in the schem, and, according to the scem, pins 25-28 are used for the data bus, not the control pins. The control pins look to be on 7,8,9,and 10, but as there are several jumpers, and jumpers from jumpers, and they are not labeled on the shield, Im going in circles. add that to the fact that the Scem doesnt show the RS or WR pins, and alternate names need to be assumed ( RS=DC=A0 ) and there are at least 2 DC pins on the schem, a couple W\R options.

Im pretty sure, if Im to believe the scem, that arduino pins 9 and 10 are CS and RST respectively, but the RS and WR pins could be any combination of arduino pins

Has anyone gotten this to work? I may have another display i can try, possible i have a bad one, but the more i dig into this the more i think im just not setting the control pins right, or not initializing the tft correctly. Would realy like to use this display, and keep the 16 bit mode, i care much more about speed than pins.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6236 attached by default, 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.

The pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

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 (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.

HiLetgo is located in China. We are a Big & Professional Electronics Modules, Sensors and Robort Parts Manufacturer, we have our own Brand "HiLetgo", products including Develop Boards like Uno, MEGA, Pro mini, Nano, ESP8266, ESP32, Power & Drive modules, Sensors, Breadboards, Connectors and Jumper Wires etc.We are committing ourselves to provide the Newest products with High quality and competitive price to the people at all over the world!

If you don"t edit the header file for the driver type the examples still work, but the colors are wrong. I think it"s because this thing uses 5 bits for red and blue but 6 bits for green.
