# Uncomment some or all of these to enable the optional hardware interfaces
# Params:
#         i2c_arm (default "off")  Set to "on" to enable the ARM's i2c interface
#         i2c_vc (default "off")   Set to "on" to enable the i2c interface
#                                  usually reserved for the VideoCore processor
#         i2c                      An alias for i2c_arm
#         i2s (default "off")      Set to "on" to enable the i2s interface
#         spi (default "off")      Set to "on" to enable the spi interfaces
#         act_led_trigger (default "mmc")
#                                  Choose which activity the LED tracks.
#                                  Use "heartbeat" for a nice load indicator.
#         act_led_activelow (default "off")
#                                  Set to "on" to invert the sense of the LED
#         act_led_gpio (default "16" on a non-Plus board, "47" on a Plus)
#                                  Set which GPIO pin to use for the activity LED
#                                  (in case you want to connect it to an external
#                                  device).
#
#         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_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.
