Day 30: final day

This post is part of the GaSiProMo challenge.   You can read more about this here.

I’ve got most of the bugs ironed out in my display interface, but not all have been squashed in the driver portion.  In other words, the method in which I can input text into the OsRAM is working nicely (I’m using a serial port console), but the nuts and bolts of how strings are sent to the display — arguably the most important part of this project — remains broken slightly.

The problem is that I was lazy.  I should have paid more attention to the WR and CE lines for proper data latching into the display at the right times.

Oh well, what can I say?   I got distracted by another project.  So I can show you what I have so far:

But this challenge has been fun.  It’s always fun to work under a deadline to see what you can do.  This forced me to learn more about Arduino.  And despite my first impression, I’ve come to see that it’s pretty great.  I especially love the C++ class support.  For instance, its string and bitwise libraries are awesome.  There are things that aren’t so great, like the editor.  I had consistent undo (CTRL+Z) wonkiness that scared me (I was afraid of code-eating), so I switched quickly to Notepad++ with a good syntax language profile.

Until next year.
