Using SD Cards / Nokia 6100 Displays with an ARMmite

Development Boards MicroMod
1

Libraries and demo source code in the Oberon-07 programming language for accessing SD cards and the Nokia 6100 132x132 colour LCD display on the Olimex LPC2378 board have now been developed for inclusion in the next release of the Armaide development system.

I’m investigating how to setup hardware options to provide these additional features for ARMmite users as well. The most accessible approach seems to me to be to use something like the SparkFun breakout boards:

LCD Display:

SD / MMC:

Has anybody gone already tried connecting these boards to an ARMmite? If so it might save me ‘reinventing the wheel’.

Or is there a better way?

I have that LCD display and have been able to drive it from an SPI port on a Luminary ARM. There is a lot of code on the web about how to set it up.

Thank you for your feedback. However, the software is no problem for me. What I would really like to know is the easiest / best way to physically connect the breakout board to an ARMmite without having jumper wires going all over the place.

Roger. I went with the SFE breakout board as well, very easy to attach the signals. Edit - I soldered a section of inline header socket to the breakout board, providing a downward facing female row, then soldered a compatible header onto the base board, providing upward facing male pins. Snaps together easy. Obviously for ruggedization I’ll need to put screws and standoffs through the mounting holes too.

I presume when you say Armmite you mean the Armmite and NOT the ArmmitePRO

I did a ‘top’ board for a lcd and a micro-sd once upon a time. I place the lcd on top long-wise and a gps module. The micro-sd was underneath.

It would use a 32pin connector near the center of the armmite.

I have since learned all the tools to dev a pcb, and have a couple of vendors. I can also make 1-2 crude ones in my garage.

Let me know, I can do a pcb cad and schematic … maybe we can trade.

EDIT: looks easy enough to do. Give me your schematic/pin connects and I will do up a board for you.
