# WAKE_REASON_ACCELEROMETER = 1 # Accelerometer activity/inactivity detection
# WAKE_REASON_PUSH_BUTTON = 2 # Pytrack/Pysense reset buttom
# WAKE_REASON_TIMER = 4 # Normal timeout of the sleep interval
# WAKE_REASON_INT_PIN = 8 # INT pin
Note: the
WAKE_REASON_INT_PIN
can be used if the PIC_RC1 pin (pin#6 on External IO
Header) is toggled.
As in the above example, this method should be called at the beginning of the script, to find
out the reset (wakeup) reason.
pytrack.go_to_sleep([gps=True])
Puts the board in sleep mode, for the duration, which has to be set previously with
pytrack.setup_sleep(timout_sec)
. The optional boolean parameter sets the GPS state
during sleep.
MicroPython code, which is after this function, is not executed, as wakeup will restart
MicroPython.
pytrack.setup_int_wake_up(rising, falling])
Enables as wakeup source, the accelerometer INT pin (PIC - RA5). The boolean parameters
will indicate rising edge (activity detection) and/or falling edge (inactivity detection) is
configured.
The accelerometer (class
LIS2HH12
) has to be also configured for a certain acceleration
threshold and duration. Code snippet:
from pytrack import Pytrack
from LIS2HH12 import LIS2HH12
py = Pytrack()
acc = LIS2HH12()
# enable activity and also inactivity interrupts, using the default callback handler
py.setup_int_wake_up( True , True )
# set the acceleration threshold to 2000mG (2G) and the min duration to 200ms
acc.enable_activity_interrupt( 2000 , 200 )
pytrack.setup_int_pin_wake_up([rising_edge = True])
Enables as wakeup source, the INT pic (PIC - RC1, pin#6 on External IO Header). Either
rising or falling edge has to be set, by default it's rising edge.
