RepRapDiscount Full Graphic Smart Controller on RUMBA

Determining the u8glb constructor call parameters for this LCD controller on the RUMBA 3D printer controller.
This started out as trying to find a simple way to test if the Full Graphics Smart Controller I had worked or not (this was before I found out I had to flip the two ribbon cable connectors over). It took a bit of detective work to get to the bottom of this. It turns out, some insightful comments in one video led to finding the answer in the Marlin firmware source code.
I think this Marlin source code is a really excellent source of information as 3D printers incorporate so many different things, LCD displays, SD cards, stepper motors, temperature sensors, PWM control, etc. And these things have been built with dozens of different versions of all the above and all those combinations of things are right there in the source code, just waiting to be uncovered.
Here's my modified u8glib examples with the RAMPS 1.4 and RUMBA controller board constructor calls:

R Brown, I did exactly exactly as the zeeproduction video recommended, but that line of code also did nothing for me. I even saw the comments low down in the comments section that you mention, but I was(still am) too much of a noob to put it to any constructive use! hopefully your method works out for me. Ill keep you updated on my progress. Thanks :D

cool test program

[@The4Crawler]

It sure is, lots of good test programs can be found in all the Arduino code examples. At least now I can figure out how to get some of those working on this more elaborate hardware like the RUMBA and RAMPS boards. It's easy with a little Arduino Nano, plug in a few jumper wires into the designated pins and you are up and running. But here, the connectors are already installed and you need to figure out how they are wired.

would you be willing to share your test program? I have a Rumba and a Mini 2864 I'm trying to get up and running. Have you got it all working now? You can PM me on FB if you like.

Sure, links to the test programs are in the video description. They are the standard u8glib test programs, just with the pin descriptions for the Rumba board added in.
