Topic: Is there a fast TFT Display for the Arduino Due? (Read 2480 times) previous topic - next topic

Since the Arduino Due has a reasonable speed (84 mhz) for pixel processing on a display, I wonder if there is a display that can benefit from the performance of the new Arduino.
I had two TFT display before. The first one was veeeeery slow and the second one was the SmartGPU, which I think shouldn't show a difference when used with the Arduino Due since the calculations are done on the TFT screen GPU itself.

The question is: Is there a TFT display specifically dedicated for the Arduino?

Greetings.

Are these compatible with Arduino i.e. are there driver sources for the Arduino? Also it would be very nice if they would be shields because it would be easier to connect.

I don't know, I've not used any displays like this yet. Too much coding for me.

Pick one, mount it on a protoboard with pins where you need connections, and a couple others for stability, shouldn't be hard.

I have a Due and the SmartGPU... definitely some library work needed.
working on it now.

From the looks of it, the Arduino Due has a USB jack for keyboards/mice and other stuff. So you should be able to connect a display device via USB, right? Well I don't know it such thing exists, but it would be awesome. Even greater if you could hook up a USB hub to the Arduino and connect keyboard AND mice AND a screen to the Due. Is that possible? Can the Arduino Due handle USB hubs?

You Might get an answer... In the Due forum section. Here:    http://arduino.cc/forum/index.php/board,87.0.html

Thanks.
I think I'll take a closer look at what the Gameduino can do and if it's compatible.

Bye.

I'm using MOD-VGA32 from Olimex (full compatible GameDuino) and is very fast.
I'm using SPI connections of Arduino Due and I have not problem just impossible to compile the GD library on due.
I worked with SPI.h (SPI.setClockDivider(9, 4); very fast) and write some test functions and it's ok !

read http://arduino.cc/en/Reference/SPI and http://arduino.cc/en/Reference/DueExtendedSPI

PS : if you want read memory you have to set clock divider to : SPI.setClockDivider(9, 10)
