# 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_mcu: mcu
# The name of the micro-controller that the SX1509 chip is connected
# to. The default is "mcu".
#i2c_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
# this is one out of the following addresses: 62 63 112 113. This
# parameter must be provided.
#i2c_bus: 0
# If the I2C implementation of your microcontroller supports multiple I2C
# busses, you may specify the bus number here. The default is 0.
