FoldaRap LCD case

Hi,

It is only an earlier RP case for a custom Panelolu with a 16x2 LCD display, encoder, contrast trimpot and reset button. No SD yet :\





It is hardcoded with OpenSCAD, so please, do not open the .scad source file if you don't want to have a nigthmare (no comments, no parametric, ... no nothing



But it has some cool things:

• It is a one-piece part that can be printed without support.
• It can be attached to both front (except for the new foot-front version without bottom extrusion) and rear extrusions.
• It leaves the top base extrusion empty to allow the FoldaRap #NUMBER plate

I am not a designer, neither a programmer, so feel free to change, improve, or destroy it in any way you want.

Nice work!

Good to see OpenSCAD being used (self confessed scripted CAD evangelist here!)

I have a Melzi board with a 1284P Atmega chip. I want to connect a Hitachi HD44780 LCD screen. Which pins connect unto the ISP or the EXT connectors. I think I have the pins lined up except for the R/S (Register Select) pin. I don't know where R/S connects to on the Melzi board connectors or even on the Atmega 1284P chip.
Also, do I have to change the pin settings in pin.h of the firmware?

Try this: [reprap.org]

LCD pin 4 which is the RS signal is pointing to the PWM D12 pin on the Sanguinololu. The Melzi does not have a PWM or D12, what gives?

This maybe a great info for you: [blog.think3dprint3d.com]
or
Maybe you can try my SPI display solution: [plus.google.com]

that still does not answer the question. The paneloulu 2 or i2c is a complete different setup than what I want to do. I just want to hook up a standard hitachi LCD without clicker encoder, contrast pot or reset switch. Just so I can see maybe bed,extruder temp or some basic features.
I'm just missing the connection to the RS signal, I need to terminate this somewhere unless it is not used but the HItachi schematics shows this has to be connected somewhere.

You just need to compare both Sanguinololu and Melzi espansion hader and figure out what pin replaces Sanguinololu D12 in Melzi. There are a loto of information about this two boards in the wiki.
