Hosyond 3.5 inch 480X320 TFT Touch Screen Module LCD Display Shield with SD Card Socket Compatible with Arduino R3 Mega2560

Check their website - they have example code and manuals (EN & CN) for this specific display, Noticed some folks had problems with the touchscreen. Often with these the display has 0/0 for X/Y coordinates in upper left corner which rotates if the display is rotated. Touchscreen may have 0/0 in bottom left which does not rotate with the display. May appear to not work because touchscreen isn't mapped correctly in your code.

NOTE: This is ONLY for Arduino UNO, NOT for Arduino MEGA2560! The I2C and SPI serial pins are in different locations on the UNO vs the MEGA. Hence, the uSD Card interface and the touch screen will not work on the MEGA. I have tested it on the UNO and everything works great (albeit a little slow), but the SD Card and touch do not work on the MEGA2560. If you don't need the SD Card or touch on the MEGA, the LCD works and looks nice .

You need to use MCU_Friend. That library brings this screen directly to life. I haven't used the SD slot yet.

Replaced a supposed better shield with this one. This shield has clear text, good color and graphics and is easy to program.

It works. Touch also works.

I'm using this display on an Arduino Mega which the display plugs into. I found that when the Mega is powered from the IDE computer the touch screen works well. Unfortunately, when powered by a 5vdc power supply on the 5v and Gnd pins, the touch screen is inconsistent when responding to stylist. By checking the voltage, I found that the IDE power is 5v while my power supply is 5.3v. By adding a 2.2 ohm resister in series to the 5v supply lower the voltage and the touch screen responds much better. My real problem is that I have been unable to get the SD card interface to work. The sample code says to use pin 53 for the SD-SS on Mega which fails to initialize. The SD-SS pin is actually plugged into pin 10 on Mega but setting the software to pin 10 also fails to initialize. I guess my biggest grip is that Hosyond customer service is nonexistent, or at least I can't find anywhere to ask the question.

I originally bought the Hosyond 3.2 display and wired it myself to my Arduino Uno and Arduino Mega2560 - checking multiple times. Could not get it to work. So I bought this 3.5 model as it specifically states that it plugs directly into the Arduino and ‘does not need wiring’. I have tried every combination of board, settings, library installs etc. They simply do not work as advertised - a complete waste of money

This one is perfect
