On GitHub, MarlinFirmware/Trinamic_TMC2130 has picked up 8 stars, C++. Arduino-compatible library to configure the Trinamic TMC2130 stepper motor driver
Snapshot summary built from the project's own GitHub metadata — there's no written TopGit review yet. The page will update automatically when a full review is published.
WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
This library makes it easy to configure the Trinamic TMC2130 stepper motor driver found on Watterott's "ludicrous" version of the SilentStepStick motor driver, which has it's repository here. It's also used in my Marlin Fork, which gets you up and running if you actually want to use these beasts in a 3D-printer-like machine.
Features
Basic status readings
All methods follow the naming convention in the datasheet.
All configurable parameters implemented
To do
Full status report
Some readable parameters are missing
How to use
Please check out the example sketches for further information.
The datasheet contains a quick start guide
Status methods (return boolean status information)
All methods follow the naming convention set_ respectively get_ and return the SPI status flags or the requested parameter.
All methods expect the encoding stated in the datasheet, with the following exceptions:
set_mres() sets the microstepping resolution and expects the integer values 1, 2, 4, 8, 16, 32, 64, 128, 256 e.g. set_mres(128)
set_IHOLD_IRUN() sets the holding current, running current and holding delay, e.g. set_IHOLD_IRUN(31,31,15)
set_MSLUTSTART() sets start_sin and start_sin90
set_DCCTRL() sets the dc_time and dc_sg
set_XDIRECT() features an alias that lets you pass the currents for coil_a and coil_b as 16 bit signed integers (the range is still +- 254, though) e.e. set_XDIRECT(254,254)
Configuration Methods (write configuration parameters to the driver)
yes, just install the library and download the Marlin Fork
Troubleshooting
Why doesn't it work
If you're using the SilentStepsStick driver, did you myStepper.set_I_scale_analog(1)?
Did you specify myStepper.set_tbl(1) and myStepper.set_toff(8) (example values)?
Did you specify a motor current myStepper.set_IHOLD_IRUN(31,31,5);?
