gEDA-user: always build a prototype!

[DJ Delorie <dj-atMUNGEDdelorie_dot_com>]

I hooked up the bigger OLED to the protoboard today, and it didn't
work.

Much panic ensued.

It turned out I had SDI and SCK swapped in the symbol.  A simple wire
switch and it worked fine, tweak the schematics and board and
continue.  Had I not done this test, I would have fabbed the board and
had a dead display.
