Full step mode with A4988 driving a NEMA-17 (200 steps per 360 degrees) with one output from the FPGA (button 0 is wired to the output IO(0)) and direction is strapped to a fixed direction.

To make sure the change I did to the original demo does what I want it does, I check the output pin with a LED and a series resistor of 220 ohm.

This is what you need to see appearing inside the tera terminal whenever you press a button.

1. Started a contract for an exciting startup.
2. This (and I mentioned it briefly before) is not just an open source FPGA for 3D print project, this is my springboard to a startup. Very important companies were started as a side business in a garage, Apple, Microsoft.

For a startup one does not need:

• Investors: nice to have, but as a side project it doesn't need much except buying parts and potentially licenses/software. That is why I do contract work.
• A business plan, market or anything, I start from my own dire need, it is system thinking, not goal thinking. Of course there is more to it, but now is not the right time.

For a startup one always needs:

• A rythm: my days are all roughly the same. Your body needs a bio clocked rythm, get up and go to bed at around the same time. I never sleep in in weekends, I maintain the same rhythm every single day. And that is a learned ability.
• Maximum focus on nutrients (Magnesium, vitamine, zinc, iron, ..), your mind needs certain ...

• I ordered some Molex ATX (PC supply) connectors to connect 12V in a safer way and it has 3.3V as well. Had to wait until they arrive.
• Vunit verification of the AXI lite slave.
• Find an AXI lite VHDL master to access the register map of the slave.
• Define the register map of the motor slave:

• one enable disable bit RW.
• status bit enable/disable, one bit.
• current position (status).
• new position (RW).
  And position =

• no of steps in 360 turns of the motor (NEMA 17 = 200).
• mm in x/y/z per turn (depends on the axis).
