* Revert "itersolve: Implement a step+dir+step filter"Kevin O'Connor2020-03-051-3/+0
| | | | | | | | This reverts commit c9cb462f90a68deb73cacb179f7bbcde2cb9aeed. The step flushing for this commit was not complete. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Implement a step+dir+step filterKevin O'Connor2020-03-041-0/+3
| | | | | | | | | | Some stepper motor drivers do not respond well to rapid "step + direction change + step" events. In particular, it is believed this can cause "over current" events on the tmc2208 drivers when they are in "stealthchop" mode. Detect these events and remove them from the generated step times.

* itersolve: Add ability to query the active_flags stateKevin O'Connor2020-01-231-0/+1

* itersolve: Rename scan_pre/_post to gen_steps_pre/post_activeKevin O'Connor2019-12-101-2/+2
| | | | | | Rename the variables to make it a little more clear what they do. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Support step generation in lead up to and after stepper activityKevin O'Connor2019-11-211-1/+2
| | | | | | | | | | | Add support for generating steps from kinematic functions that calculate step times based on a range of the motion queue. It requires scanning for step generation during the lead up to stepper activity (when the stepper would nominally be idle). And it requires scanning for step generation just after a stepper has nominally become idle. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Remove set_commanded_position() callKevin O'Connor2019-11-131-3/+2
| | | | | | | | Now that the only caller to set_commanded_position() is set_position(), remove the set_commanded_position() method and pass the set_position() call directly to the itersolve.c code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Remove unused gen_steps()Kevin O'Connor2019-11-061-1/+0
| | | | | | | Eliminate the old gen_steps() call now that all callers have been converted to the newer trapq based generate_steps(). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Add support for generating steps from a trapqKevin O'Connor2019-11-061-0/+13
| | | | | | | Support associating a stepper_kinematics with a trapq. Support generating steps from a time range on the given trapq. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* trapq: Add new trapq.c file with code for trapezoidal velocity handlingKevin O'Connor2019-11-061-27/+2
| | | | | | Move the "struct move" code from itersolve.c to new file trapq.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* itersolve: Support calculating a stepper position from a cartesian coordinateKevin O'Connor2018-07-181-2/+2
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* itersolve: Support setting the stepper position via a cartesian coordinateKevin O'Connor2018-06-221-0/+3
| | | | | | | | | Add support for an itersolve_set_position() function that sets a stepper position from a cartesian coordinate. This eliminates the need for both the python and C code to be able to translate from a cartesian coordinate to a stepper position. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
