OnBoard SPI Drivers use the SPI independent mode, so each driver needs its own cs_pin
Example Yaml code
motor1: limit_neg_pin: NO_PIN limit_pos_pin: NO_PIN limit_all_pin: NO_PIN hard_limits: false pulloff_mm: 1.000 tmc_2130: r_sense_ohms: 0.110 run_amps: 1.2 hold_amps: 0.1 microsteps: 16 stallguard: 0 stallguard_debug: false toff_disable: 3 toff_stealthchop: 5 toff_coolstep: 3 run_mode: StealthChop homing_mode: CoolStep use_enable: false cs_pin: i2so.11 step_pin: I2SO.10 direction_pin: I2SO.9 disable_pin: I2SO.8 spi_index: -1 ### // for SPI independent mode spi_index: -1
Option D: External SPI Drivers
Common Models:
- TMC5160
Important: Take off corresponding SPI jumpers to enable signal output to External SPI Drivers via Green Terminal, plug driver slot jumpers.

External SPI Drivers use the SPI Daisy Chain mode, so each driver needs only one cs_pin (default: I2SO.3)
Example Yaml code
motor0: limit_neg_pin: NO_PIN limit_pos_pin: NO_PIN limit_all_pin: NO_PIN hard_limits: false pulloff_mm: 1.000 tmc_5160: r_sense_ohms: 0.1 run_amps: 1.2 hold_amps: 0.5 microsteps: 16 stallguard: 0 stallguard_debug: false toff_disable: 0 toff_stealthchop: 5 toff_coolstep: 3 run_mode: CoolStep homing_mode: CoolStep use_enable: false cs_pin: i2so.3 ######## // for daisy chain i2so.3 No configuration required below. step_pin: I2SO.2 direction_pin: I2SO.1 disable_pin: I2SO.0 spi_index: 1
Option E: Regarding Mixed Use
โ ๏ธ SPI Mode Incompatibility
- SPI mode is not compatible with other driver modes.
- On-board SPI drivers and external SPI drivers cannot be mixed.
โ Compatible Configuration
On-board StepStick drivers can be mixed with standard external drivers.
Important Note for Mixed Setup:
Pay close attention to jumper settings when mixing driver types.
๐ Jumper Configuration Guide
When Using On-board Drivers:
There should be no jumpers in the driver slots.
When Using External Drivers:
- Insert the jumpers into the driver slots
- Step (Stp) and Direction (Dir) signals must be output from the green terminal blocks
