# to not scale the 'wiper_x' parameters.
# Configure an SX1509 I2C to GPIO expander. Due to the delay incurred
# by I2C communication you should NOT use SX1509 pins as stepper enable,
# step or dir pins or any other pin that requires fast bit-banging. They
# are best used as static or gcode controlled digital outputs or hardware-pwm
# pins for e.g. fans. One may define any number of sections with an "sx1509"
# prefix. Each expander provides a set of 16 pins (sx1509_my_sx1509:PIN_0 to
# sx1509_my_sx1509:PIN_15) which can be used in the printer configuration.
#[sx1509 my_sx1509]
#address:
# I2C address used by this expander. Depending on the hardware jumpers
# this is one out of the following addresses: 0x3E 0x3F 0x70 0x71. This
# parameter must be provided
#bus: 0
# If the I2C implementation of your microcontroller supports multiple I2C
# busses, you may specify the bus number here. The default is 0.
# Configure a TMC2130 stepper motor driver via SPI bus. To use this
# feature, define a config section with a "tmc2130" prefix followed by
