Detailed Description

coolStep smart current control and stallGuard2 configuration register (COOLCONF)

Configuration for smart current control and stallGuard2 stall detection.

Bit assignments per datasheet:

Bits 3..0: semin3..semin0 - Minimum StallGuard2 value for smart current control and smart current enable (4 bits) %0000: smart current control CoolStep off %0001...%1111: 1 ... 15
Bit 4: Reserved, set to 0
Bits 6..5: seup1..seup0 - Current up step width (2 bits) %00...%11: 1, 2, 4, 8
Bit 7: Reserved, set to 0
Bits 11..8: semax3..semax0 - StallGuard2 hysteresis value for smart current control (4 bits) %0000...%1111: 0 ... 15
Bit 12: Reserved, set to 0
Bits 14..13: sedn1..sedn0 - Current down step speed (2 bits) %00: For each 32 StallGuard2 values decrease by one %01: For each 8 StallGuard2 values decrease by one %10: For each 2 StallGuard2 values decrease by one %11: For each StallGuard2 value decrease by one
Bit 15: seimin - Minimum current for smart current control (1 bit) 0: 1/2 of current setting (IRUN) 1: 1/4 of current setting (IRUN)
Bits 22..16: sgt6..sgt0 - StallGuard2 threshold value (7 bits, signed) -64 to +63: A higher value makes StallGuard2 less sensitive Zero (0) is the starting value working with most motors
Bit 23: Reserved, set to 0
Bit 24: sfilt - StallGuard2 filter enable (1 bit) 0: Standard mode, high time resolution for StallGuard2 1: Filtered mode, StallGuard2 signal updated for each four fullsteps
Bits 31..25: Reserved, set to 0
