# 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.
