7 inch tft display with SSD 1963 touch screen shield. Using on an Arduino DUE

Using Arduino Displays
#1

I recently purchased one of these combos from buydisplay.com. I have tried everything I've read on here to no avail. I'm using the shield but checked my voltages anyway and they are good. I think I've modified the libraries as mentioned in other posts. (But honestly I'm not sure about that.) I'm trying to use the examples that come with the libraries so I won't post them, under the assumption that if your familiar with this topic you've come across the examples before. That said I will add them if someone asks. The site says everything one needs to get this display up and running in 10 minutes. I've been at it for 3 weeks. So odds are it's user error.

This is the exact display and shield I purchased if it helps https://www.buydisplay.com/default/7-inch-arduino-touch-screen-shield-ssd1963-library-for-mega-due

If anyone could break down the process to get this display to work (as if you were explaining it to a child apparently) I would appreciate it.

Hi and welcome.

The site tells many things and offers a datasheet to the shield. Telling us you did all you can, doesn't tell us what you actually did or did not do.

The datasheet shows the presence of jumpers (solder pads really), which will enable or disable certain functions. And you are told multiple times on the site as well as in the datasheet, that you need to power the shield and display using an external 5 Volts 1 Ampere power supply, because this kind of power can't be drawn form a (any) Arduino.

So did you check the jumper settings, and did you use an external power supply for the shield ?

I was under the misguided assumption that if I used a power supply for the Arduino Due board instead of just powering it with the usb from the computer that would be sufficient.

I ordered a dedicated power supply for the shield and see what if that works.

I haven’t tried the jumpers. (I honestly didn’t know the shield had movable jumpers)

As for what I did try. I only found 2 articles that were due specific. One was a different set of drivers. However the shield specifically said 1963.

There was another that says to uncomment a line. But it doesn’t say if it’s in a library the sketch or somewhere else. I searched all the above but couldn’t find the line anywhere.

There are no jumpers you can move around. They are solder pads (which are real close to each other), and you need to apply a blob of solder to connect them. If no solder is on them, then nothing has been set. I don't know whether the shield assumes some default setting if no jumper has been set or not, you have to check that for yourself or just make the correct settings.

Read the manual. Read the manual. Read the manual.

There is a thread which deals with a SainSmart TFT display touch screen. This is not yours, although some tips may be usefull, see reply #13:

I did read the manual. That screen and shield are designed to work with each other as is. I’ll try the dedicated power supply if that doesn’t work I’ll seek help elsewhere. Sorry I bothered the help forum with my rudimentary understanding of touch displays. Won’t happen again.

You didn't understand what i was telling you. I did not (mean to) attack you. Sorry if you read it that way.

Reading a manual (or my posts) once is most of the times insufficient. I think it's clear you missed parts of what that document has to offer. Read it multiple times after each other, you will better understand what it says.

By the way, this forum is for and from Arduino users. It is not some manufacturer help desk. I get that you might become a bit frustrated, but don't blame that on this forum or on me.

What do you mean when you say you cant get the screen to work? Do you get nothing on the screen at all? No reaction from the screen when touched? No communication when reading/writing to the SSD? I have the exact same screen and have it up and running on an arduino mega. The libraries and examples work for me right out of the box without the need for modification.

As for the power requirements, I can run the screen and all of its advertised functions without the need for an external power supply. I simply plug a USB programming cable into the mega and into my laptop and everything works fine. Of course, for use outside of a dev environment, I use a 5V 1A power supply that happily runs the arduino and screen.

I'm in the same boat as Roin316 in that I a bought a combo screen, shield and mega(Serial SPI Arduino 7"TFT LCD Touch Shield RA8875 for Mega/Due/Uno) from BuyDisplay. It works great right out of the box with the code that was preloaded into the Mega. So I had an extra Mega board that I swapped out and loaded the libraries and example code from the website. With the website code the display is dead. No backlight, only power LEDs light up. Have tried several different examples all with the same result. As the display works with the Mega board purchased with the display and shield, there must be something different in the code on the website verses what was preloaded from BuyDisplay. One thing that I found that is different is the model numbers on the website indicate ER-TFTM070-5 and the model number on the board is ER-TFTM070-4.

Does someone have suggestion on where I might find the code the was shipped with the Mega from BuyDisplay?
