The basic prerequisites for the driver to start operating on the software side are
- off time > 0
- run current > 0
The Simple
example makes a call to the begin
method which then pushes the default register values into the driver.
Digging through the code you can see the boot time defaults here: https://github.com/teemuatlut/TMC2130Stepper/blob/master/src/TMC2130Stepper.h#L414
// Shadow registers
uint32_t GCONF_sr = 0x00000000UL,
IHOLD_IRUN_sr = 0x00000000UL,
TSTEP_sr = 0x00000000UL,
TPWMTHRS_sr = 0x00000000UL,
TCOOLTHRS_sr = 0x00000000UL,
THIGH_sr = 0x00000000UL,
XDIRECT_sr = 0x00000000UL,
VDCMIN_sr = 0x00000000UL,
MSLUT0_sr = 0xAAAAB554UL,
MSLUT1_sr = 0x4A9554AAUL,
MSLUT2_sr = 0x24492929UL,
MSLUT3_sr = 0x10104222UL,
MSLUT4_sr = 0xFBFFFFFFUL,
MSLUT5_sr = 0xB5BB777DUL,
MSLUT6_sr = 0x49295556UL,
MSLUT7_sr = 0x00404222UL,
MSLUTSEL_sr = 0xFFFF8056UL,
CHOPCONF_sr = 0x00000000UL,
COOLCONF_sr = 0x00000000UL,
DCCTRL_sr = 0x00000000UL,
PWMCONF_sr = 0x00050480UL,
tmp_sr = 0x00000000UL,
TPOWERDOWN_sr = 0x00000000UL,
ENCM_CTRL_sr = 0x00000000UL,
GSTAT_sr = 0x00000000UL,
MSLUTSTART_sr = 0x00F70000UL;
After that an off time
value and a typical blank time
setting is set.
Finally the example sets the run current.

Thank You very much! I analysed Your settings carefully and implemented them into my code - and the motor finally moved. It seems everything is working as it should be. Thank You again!
