Android Device to Micro Controller to OLED Screen?

[Romoko]

Okay here's what I'm proposing.

I want to run a usb from an Android device to a micro controller that then displays basic inverted text to a simple OLED screen.

The objective is to have the OLED screen be reoriented when placed perpendicular to a transparent piece of plastic. A "Heads Up Display" if you will.

Thoughts?

I'd suggest looking into this:

http://developer.android.com/sdk/ndk/index.html

It's android's dev platform for C/C++. I imagine there are a few libraries in there that will give you access to the hardware... and then you can start writing your routines.

I'm not really sure what your end goal is since you don't give any real detail. But with the NDK you could have the android device output data via rs-232 on the usb port or something easy like that.

I'd also suggest looking into the beagleboard and pandaboard dev platforms:
http://beagleboard.org/
http://pandaboard.org/

both dev boards are open source and use hw that you'd typically find in a modern android phone. it'll also be easier to interface external hardware with the dev boards rather than your android phone.

Wow those boards are exactly what I would need. My approach was a lot more crude.


I'm prototyping a HUD for my motorcycle helmet that displays via a mirror image

a cheaper and simpler approach would be the arduino dev platform

http://www.arduino.cc/

they arent nearly as powerful as the panda or beagleboards but they'll be a lot more accessible for newbies. really just depends on your comfort level with the stuff.
