Sainsonic 3.2 Touch screen + SD Card Reader

Keep A close look on this site.  I'm currently working on a modifed touchscreen library that works for the cheap ass sainsonic 3.2 Ardunio touch screen.  I'm implementing a first in forget the crap data policy for touch based apps.

I'm catching the glitches so it'll forget those 100px jumps that glitch the app I'm building using a modifed a UTFT libary that reads images from folders with SDFAT.

How to fix your Sainsonic Mega 2560 R3 timeout on Upload Arduino Mega

The Problem:

 Hey Guy's I was stuck for a tic and thought you might like to know how to fix
this problem with your arduino clone or similar Mega after I saw so many people
with the same issue.
 
Arduino IDE Console Output:
______________________________________________________________
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer

If you've installed your drivers and it's still doing this you need to do the following.

The Fix:

Windows 7:

Go into device manager (Right click computer, click properties, click device manager)

Go to Com Ports

Delete Ardunio com port (Com 1 on my machine)

Rescan the computer's plug and play with the magnifying glass icon or press F5

Then the proper driver will install and you'll notice an extra port appears!

You will find an extra com port now available on the Arduino IDE which will let you use your new toy!

Profit_Vanity and Sainsonic are not at fault Thank Microsoft :D







How to use the UTF library on Sainsonic Mega 2560 R3 with 3.2" TFT

How to use the UTF library

From the great guys at  www.henningkarlsen.com/electronics

Here's the initial parameters I've used to run this screen.


UTFT myGLCD(GEEE32,38,39,40,41);


Haven't tested the touch screen yet, But the demo runs!

LATEST UPDATE :

BMP VIEWER EXAMPLE FOR SAINSMART MEGA 3.2 TFT

Sainsmart Show BMP TOUCH Example

UPDATE:
I've had limited success with the touchscreen so far,
But an app I found modded from sainsonic works so well
that I'm building a decent Library to drop the glitch data
from UTFT.
