6.11 Device Initialization
The following sequence of SPI commands is an example of enabling the driver and initializing the
chopper:
SPI = $901B4; // Hysteresis mode
or
SPI = $94557; // Constant t
off
mode
SPI = $D001F; // Current setting: $d001F (max. current)
SPI = $E0010; // low driver strength, stallGuard2 read, SDOFF=0
SPI = $00000; // 256 microstep setting
First test of coolStep current control:
SPI = $A8202; // Enable coolStep with minimum current ΒΌ CS
The configuration parameters should be tuned to the motor and application for optimum
performance.
