I've recently brought a TFT screen from Buy Display
which I'm looking to use with the Arduino Mega, to do this the datasheet say that logic level is 3.3V which means i need a logic level converter. So I've connected the Arduino Mega to the logic level converter then onto the screen SPI pins on the screen.
they have an Arduino Shield that they also sell:
at the bottom of the page is an Arduino library for driving the graphics chip with the shield, from what i can see all the shield is just a logic level converter for the screen, I've got this from the schematics and my understating of Arduino logic.
So will the library that they supply with the shield work with the set up i have created? I cant see why it wouldn't but when i connect it all up the screen is not working, its black but their is data on the pins on both side of logic level converter, I was using one of Buy Displays Arduino Mega examples that come with the library on the shield page, I've made sure I've changed the CS but its still not working and i cant see why it wouldn't work.
