Address and data bus lines are now connected between the ‘595s and the SRAM. The breadboard has gotten unworkable. It’s time to take a different approach. Choices:
- Move to protoboard and do permanent wiring underneath with headers on top for further experimentation.
- Split out into two or more breadboards with ribbon connectors between them. This isn’t actually any better than what I have now, but it’d be a chance to refactor the wiring and IC arrangement.
- Fire up EAGLE and redo the circuit as a schematic, then route it and ship it off to be manufactured, maybe by DorkbotPDX if the timing works out right and I’m patient, or somewhere else if I want to spend more money and get it faster.
- Sit and wait for the Papilio One to arrive (which I ordered a couple weeks ago), and in theory enjoy working mostly in software until I run into BRAM limits.
