I think I'm misunderstanding something here.
The TMCStepper Library (by teemutatlut) initializes a driver via:
TMC2209Stepper driver(&SERIAL_PORT_2, R_SENSE, DRIVER_ADDRESS_1);
// Creates TMC driver
And there is no command that I can see that lets me set something like:
driver.setSpeed
//or
driver.runSpeed;
Which are commands that the drivers in MobaTools and AccelStepper seem to have..and I don't believe I can use MobaTools or AccelSteppel to initalize the same driver at the same time, to run those commands.
The code in #38 shows that the dir and step pins are initialized, as far as I can tell. I am struggling to find a correlation between the datasheet's explanations and the commands in the TMC2209 library, though.
