I put all the links at the bottom.
I recently bought an i2c touchscreen. The H35B-I (3.5 ", 480x320).
I have been trying for several days to program it with the Visual LCD Studio software.
Here is my problem:
The software does not want to connect with the screen and puts The Scom port don't open! (when you press "dowload bin", in the "Dowload & test" section.
I don't see why it doesn't work.
The USB port is well connected, according to my computer settings the usb device is working fine. The touch screen is blue. The connection is in ISP with the supplied cable.
All usb ports have been tested on 2 computers.
I tested with another software quickly same problem.
The screen works perfectly when used with an Arduino Uno.
I don't know if it's me who really sucks or if there's a real problem.
