# Uncomment some or all of these to enable the optional hardware interfaces
# Params:
# i2c_arm Set to "on" to enable the ARM's i2c interface
# (default "off")
# i2c_vc Set to "on" to enable the i2c interface
# usually reserved for the VideoCore processor
# (default "off")
# i2c_arm_baudrate Set the baudrate of the ARM's i2c interface
# (default "100000")
# i2c_vc_baudrate Set the baudrate of the VideoCore i2c interface
# (default "100000")
# i2c_baudrate An alias for i2c_arm_baudrate
# i2s Set to "on" to enable the i2s interface
# (default "off")
# spi Set to "on" to enable the spi interfaces
# (default "off")
# act_led_trigger Choose which activity the LED tracks.
# Use "heartbeat" for a nice load indicator.
# (default "mmc")
# act_led_activelow Set to "on" to invert the sense of the LED
# (default "off")
# act_led_gpio Set which GPIO pin to use for the activity LED
# (in case you want to connect it to an external
# device)
# (default "16" on a non-Plus board, "47" on a
# Plus or Pi 2)
# N.B. It is recommended to only enable those interfaces that are needed.
# Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
# interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
# Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
# interfaces i2c0 and i2c1. Use of the numeric variants is still possible
# but deprecated because the ARM/VC assignments differ between board
# revisions. The same board-specific mapping applies to i2c_baudrate,
# and the other i2c baudrate parameters.

# Uncomment to enable the lirc-rpi module
# Params: gpio_out_pin GPIO pin for output (default "17")
# gpio_in_pin GPIO pin for input (default "18")
# gpio_in_pull Pull up/down/off on the input pin
# (default "down")
# sense Override the IR receive auto-detection logic:
# "1" = force active high
# "0" = force active low
# "-1" = use auto-detection
# (default "-1")
# softcarrier Turn the software carrier "on" or "off"
# (default "on")
# invert "on" = invert the output pin (default "off")
# debug "on" = enable additional debug messages
# (default "off")
