- # By default, on-board LEDs are controlled by kernel LED driver.
- # To make corresponding pins be available as normal GPIO,
- # corresponding driver needs to be unbound first (as root):
- # echo -n "soc:leds" >/sys/class/leds/apq8016-sbc:green:user1/device/driver/unbind
- # Note that application also either should be run as root, or
- # /sys/class/gpio ownership needs to be changed.
- # Likewise, onboard buttons are controlled by gpio_keys driver.
- # To release corresponding GPIOs:
- # echo -n "gpio_keys" >/sys/class/input/input1/device/driver/unbind
- # User LED 1 on gpio21
- LED = Signal(Pin(21, Pin.OUT))
- # User LED 2 on gpio120
- LED2 = Signal(Pin(120, Pin.OUT))
- # Button S3 on gpio107
- BUTTON = Pin(107, Pin.IN)
