Development Notes

See circuit chatter and programming chatter.

Viable Commands

Test

Keycode: 127

  • to test networking, this will reply with a payload packet containing 127, 12, 24, 48 and will toggle an LED on the board

Reset

Keycode: 128

  • issues a software microcontroller reset
  • if the microcontroller is already hung up, this will not work

Step Trapezoid

Keycode: 131 Arguments: Steps to Make, int32_t | Entry Speed, steps/s, uint32_t | Acceleration Rate, steps/s/s, uint32_t | Acceleration Length, steps to accelerate for, uint32_t | Decceleration Length, steps to deccelerate after, uint32_t Returns: Steps Made, int32_t | on step completion

  • the stepper will load this block into its stepping buffer, and if the buffer is empty will execute the trapezoid. on it's completion, the stepper will reply with an acknowledgement

Step Wait

Keycode: 133 Arguments: Steps to Make, int32_t | Entry Speed, steps/s, uint32_t | Acceleration Rate, steps/s/s, uint32_t | Acceleration Length, steps to accelerate for, uint32_t | Decceleration Length, steps to deccelerate after, uint32_t Returns: Wait Made, uint8_t 24

  • an identical block to the step trapezoid, but with a flag to avoid actually stepping. this is used in motion planning to insert a wait block for a motor with zero steps, to retain packet synchronization

Reproducing This Work

All automatakit works are open source, and while we cannot sell you boards, if you have an interesting application, get in touch to ask about collaborating.

To reproduce boards and load code, see the document 'Reproducing Automatakit Work'
