Is there a way of controlling the Niryo One using your API, Niryo One Studio, RPi image, but instead using my own stepper drivers that do not have closed loop feedback? I want to connect my own micro-controller and stepper drivers (DRV8825) to control the arm.
What I have learned with the niryo one hardware is that you need a RPI shield that can generate CAN bus for the stepper controlers and also a stepper controler that could comunicate with the raspberry trought this CAN bus ( MCP2515).
The Raspberry Shield also need to control the Dynamixel servos ( TTL 1mbs network ), 03 wires +7 , GND and Signal – Each dynamixel has a specific id.
Take a look on the CAN Bus file inside the Stepper Firmware, you are going to learn what your need on your stepper controller.
