I tested out my Sainsmart and had no issues this time. This is what I did.
I then plugged in the SainSmart again and it was wrong, did the same steps as above for it and its working again. So same library should work. I uploaded it again with the correct calibration there. First delete the UTouch library from your documents/arduino/libraries folder and then copy this one there.
If it doesn't work my question is do you get any touch. The touch should always work just not where you expect it to. Run your finger all over the display and something should change. If it doesn't maybe your touch isn't working. My sainsmart the touch only works 75% of the screen which others have experienced.
- Plugged in sainsmart and powered up controller
- My touch worked but everything was wrong
- Copied the 7" sainsmart calibration file UTouchCD.h into the "Documents/Arduino/Libraries/UTouch/" folder and overwrote the existing file
- Open Arduino IDE and uploaded Display sketch
- After programming was complete the arduino restarted and showed the home page and the touch worked as it should
