Kit #3:Blank, white display after uploading Megalogger

[jonnyrv]

Hello,

I started a seperate topic in order to maintain a clear overall picture.

My problem:

I received my kit #3 last week. After importing the neccesary librarys for meggalogger, compiling and uploading successfully I still have a blank, white display.

I'm a complete beginner therefore I hope that someone can give me a easy example for the 3,2" display to exclude that there is a hardware damage?

Thanks in advance,

Johannes

Make sure you are using the latest code from github. You should start with no OBD or GPS connected. Make sure you compile upload the sketch successfully.

Make sure you are using the latest code from github. You should start with no OBD or GPS connected. Make sure you compile upload the sketch successfully.

I'm using the versions from 27.11.2014 (code and librarys). I compiled with success and uploaded with success. The OBD and the GPS were not connected to the display. Still same result - white screen...

[stanley]

Could you please post a picture?

[jonnyrv]

of course. A picture of the white screen or the used code?

[stanley]

Both please.

Hello stanley. I hope you can find a mistake. The picture of the white display and the used code (only config.h, the other codes are standard).

It is likely the display shiled was damaged during shipping. We will ship you a new display shield shortly. Please provide me your order number.

This would be perfect. My order-nr: 1250

Hello,

I have exactly the same problem with the white/grey display.
I bought the Kit#3 with: (Order ID: #1490)
- OBD-II Adapter: Model B (I2C + MEMS ..
- Arduino Board: Arduino MEGA 2560 R3
- GPS Module: U-Blox G6010 5Hz
- Wireless: Bluetooth 2.1
- Accessories: 8GB microSD
- Accessories: Car Window Mount

I have downloaded the newest version of the Mega-Logger here: http://sourceforge.net/projects/obdcon/files/logger/

but after compiling and uploading without any problems i still have the white blank display. (like before)
Is the display really damaged? Or is something else wrong?

Here is the config sketch, I changed nothing in all sketches.

Thank you for a fast answer because i need the Mega-Logger really urgently for my studies.
Best Regards,
