Olduino All-In-One

June 19, 2014

All the olduinos to date have been add-ons to the basic Membership Card CPU board. With the encouragement of Lee Hart I’m trying for a next generation Olduino that would incorporate everything on one board about 3.5X2.25 – the size of the current MC. Below is a block diagram for the new board. There’s an “Insert Magic Here” box at the bottom where the AVR would usually go. I’d like to try to replace the AVR with something smaller and less of a crutch. For example, an FT245RL to talk to the PC and logic that would let the 1802 clock the SPI registers at high speed on its own.
