RGB LCD shield kit with arduino mega 2560

[julienbeaumont]

Hi, i'm starting in arduino, i bought a Mega 2560 and a rgb lcd controller (http://www.adafruit.com/products/714)
I can't get it to work, I tried to compare the pin position with the picture of a uno but I don't have any result, can someone tell me precisely wich pin i must plug and where ?

[adafruit]

Is it an R3 Mega?

[julienbeaumont]

yes

[adafruit]

Can you post up a photo showing your shield and mega connected - top and sides please.

[julienbeaumont]

here is the first part

[julienbeaumont]

and these ones. Thank you for your help.

[adafruit]

connect the SCL and SDA pins from the top left corner of the shield to the SCL/SDA pins on the top left corner of the MEGA - they're next to AREF

do not connect digital 4 and 5

if you mean this, it doesn't work...

Top left, not top right. Looking from the face side of the shield.

[julienbeaumont]

did it too, was my first try ! doesn't work !

[julienbeaumont]

ok, i got the backlight working, i uploaded the program hello world, the color is changing but no text on screen...

[adafruit_support_bill]

Are you sure you didn't have SDA and SCL reversed? SCL is the pin on the far left end and SDA is the second pin in.

[julienbeaumont]

If i reverse the pins i got nothing.

If the backlight is working, you are communicating with the shield. The missing text is an indication of a soldering problem on the shield. Post clear photos of the front and back of the shield.

As far as I can see, I don't notice faulty soldering...
