DAsy chaining SPI connected Motors

Controllers Smoothie
1

HEllo All,
I am considering to use a Smoothie board to drive my Pick&Place machine.

For this machine I would like to code a Smoothie module that would be able to drive multiple pairs of Z+A(rotation) axes.
Those motors will be driven by an L6470 (or other driver with motion integrated) connected over an SPI chain.

Please help me with some pointers to :

  • other modules that drive something over SPI
  • other example of modules that are similar and may be used as source of inspiration

Kind regards,
Daniel

The digipot and panel modules use SPI.

Note this could be of interrest to you : https://docs.google.com/document/d/1yJnCG1fGhp64-zeYBpuORSVDRx_d7kL48Qw4BJoBYs4/edit#heading=h.rp764qabcdpc

Thank you for your answer Arthur !
I have found as well :
https://github.com/Smoothieware/Smoothieware/tree/edge/src/modules/utils/motordrivercontrol

and

http://smoothieware.org/advancedmotordriver
I have to inspire from them and modify them in order to drive L6470 and later to interpret g-codes.

I will come back when I will arrive there.

BR,
Daniel
