RepRap Discount LCD Display only shows gibberish

I recently upgraded my reprap with the new 0.91 Repetier Firmware and also installed a RepRapDiscount Smart Controller

The problem is that I don´t get any meaningful text displayed but something like this:

[postimg.org]

At first I thought, that it is a interference from other cables but it´s always the same and when I spin the encoder it changes. So I think that it is maybe caused by the software.
This would be my configuration.h:

#ifndef CONFIGURATION_H
#define CONFIGURATION_H

Any ideas?

My printer runs with the same controller and firmware and only FEATURE_CONTROLLER 2 matters, so I do not think it is the firmware.

If encoder work and you hear clicks the connection is correct. So I assume a hardware problem like cable problem or bad solder connection. You can switch the 2 cables to rule out the cable.

Thanks for the fast reply.

Finally I figured it out what it was. There was a really tiny connection between 2 solder points on the Adapter pcb that connects the Ramps board with the cables. Now it works like a charm

Hey

I got the same problem, but mine doesnt show anything. my Conf.h is the same as yours

I've got a similar display (red pcb from Chinese supplier on ebay) that works fine with repetier firmware, but when I tried marlin it would sometimes go nuts and display junk after working fine for a while. I did have to put a firmware patch in to slow down the encoder which generates four changes per detent. Stock repetier would skip menu items until I changed the decode table.
