itl looks realy great for netduino!

did someone get it running with netduino 2

just started and get in not to work :-(maybe someone can help me a litle bitreadRegister(byte Addr, byte xParameter) doesnt works

lol i found some soulder pads to connect the spi ;-) i try it tomorow again

Hello, did you get in to work? I just received my V2.0 Shield. Please share the code if you could successfully run the TFT display with netduino 2.0.

is it possible that that display is a realy slow thing?

is it the display or the netduino?

Did you ever get this working?  I just got one and I'm struggling.  It fails on read ID.  It gets only 0's instead of 9341.  It doesn't display anything either.  I've soldered the three headers and I've soldered the backlight to the D7 pad and all I can do is toggle the backlight.  Anyway, any help would be greatly appreciated.  Thanks.
