LCD Smart Adapter

[Highcooley]

A pity...the LCD still doesn't come with a RAMBO adapter. Making own cables is no big deal, but supplying electronic components like connectors is, due to horrendous shipping costs. Oh well, let's see, if I can find some PC flat ribbon cable from the old times...

Ok guys

Wired everything up, checked trice (followed the wires, was not able to beep it out at the moment), updated pins_arduino.c on Arduino 0023 and uploaded Johns LCD compatible firmware. But this bloody thing won't work. If I push the click encoder, I can hear a beep and sometimes the LCD backlight flickers during the push...but that's it. Sometimes, I even get a kill () called echo. But also when pushing the click encoder and not the reset button. Any suggestions what to try? I used the mentioned wiring pdf and double checked with the pdf on the reprap wiki.

Had the same problem. I downloaded Arduino IDE 022 then replace pins file and opened marlin.pde (exactly this file, not another from the project) and everything works now.

What do you mean with "exactly this file"? John's Rambo with LCD firmware?

in arduino IDE when you open any file from the project for example configuration.h all the files will be loaded. And i don't know if this make a difference if you open your marlin project by marlin.pde or another file, but for me it's working when I opened it by marlin.pde. And one thing more: when I downloaded Marlin-for-rostockmax-ramboLCD it won't work for me. I have to download Marlin-for-rostockmax-rambo and copy/paste all the setting from the Geneb manual, and everything is now working

Ok, thanks for clarification and the input with the not working ramboLCD version. Still gona try this first. Unfortunately, I edited the working rambo-without-LCD version with Arduino 1.0.1. This changed marlin.pde to marlin.ino which unfortunately is not backward compatible.

I made a version of the pins file compatible with versions 1.0 and up of the arduino app. Download it here. Note the download button is in the top right.
This goes in a different spot than the earlier versions, on the mac this is /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/variants/mega/pins_arduino.h

Hmmm, no luck so far.

Tried with altered pins_arduino.h on arduino 1.0.1 with both, john's LCD version and my old rambo version plus the LCD changes, downloaded a fresh rambo without LCD from john's git repository and did the changes in arduino 0022 with altered pins_arduino.c. But the LCD stays dark with sporadic flickering when I push the rotary knob as well as the beeping as long as the knob is pushed.

Any other suggestions for what to try next?

I try to beep out the cable, but afther that, it can only be either a software problem or either the rambo or the lcd panel is broken.

Update 02.07.2013, 08:43 pm:
Cable is beeped out and all fine. However, I got shorts on A2, B4, B6 and B8 on the LCD controller board. These would be BTN_ENC, SS, MOSI and Kill_Pin. If I take out the SSD card, B4 (SS) is not shorted to the other pins anymore. I also have ground connections between all ground pins except the rotary switch pin 4 and EXP1 (connector B) pin 9. The last two pins are connected and should both be ground.
This all makes no sense to me. Could somebody please check if he gots the same shorts on his working board?
THX a lot!

ok guys...forget everything I wrote in my last post (I still leave it here for the records). ALL SOLVED!

I fell for the PIN 10 joke, due to reading the guide properly in the office to see how it works and less concentrated at home during the soldering.

Truely sorry guys for all the hurly-burly!!

Hi Guys!

I'm in the reverse boat. I've been looking for that little "smart" adapter board for my RAMPS. If you bought the kit and aren't using the little PCB could I have it?

Thanks

Anyone notice how at random times, the guys from Seemecnc jump in and offer help.
I think that it is great that they do that and offer thanks to them.
