Week 12

Interfaces

Introduction:

Make some sort of computer interface to talk to different devices.

Workflow

Plan: Work on a way to decipher serial communication.

Design

Lincoln helped me come up with a way to read from a serial port without an FTDI port. Namely, use the programming port to decipher inputs.

After speaking with Rob, he mentioned that plugging in the FTDI signal cable to the port diagonally opposite the ground in the programming 2x3 is the signal one, and that would suffice as a communication channel.

This is useful, as the stepper motor circuit does not have an FTDI port, and debugging from that board is challenging without one.

What to do next
