Project Introduction

This project is based on HyperStepper (main) and XDrive, separates the encoder and driver, can be adapted to different types of stepper motors, and can be installed in a narrow space (the boxed version of the driver is shown, the aluminum casing is not needed and the PCB is positioned in four directions Remove the buckle, equip the backing plate and install it on the 2020 aluminum profile)

This project is the front-end of a certain project (there is a big one at the back, so stay tuned, manual work is funny)

the work i do

1. Modified some circuits, redesigned the board appearance and component layout, and redrawn the PCB

2. Modified the mode configuration method from using the driver onboard DIP switch to change the mode to adjusting the jumper cap on the controller connected to the FC cable to adapt to the definition in the XBoard E1.0 writing machine controller project Universal motor control interface, and add 4 low-speed optocouplers for corresponding circuits

3. The code was restructured, the correspondence between some pin definitions and hardware was modified, the variable names were renamed and most of the "magic numbers" were eliminated to make the code more readable.

planned work

1. Continue to reconstruct the code and split the source files according to functions.

2. Further encapsulate the function to facilitate transplantation

3. Add support for ABI incremental encoder

4. After the calibration is completed, the motor will beep to indicate that the calibration has been completed.
