示例1: signal_handler
# 需要导入模块: from PyMata.pymata import PyMata [as 别名]
# 或者: from PyMata.pymata.PyMata import set_digital_latch [as 别名]
# re-arm the latch to fire on the next transition to high
board.set_digital_latch(PUSH_BUTTON, board.DIGITAL_LATCH_HIGH, cb_push_button)
def signal_handler(sig, frame):
print('You pressed Ctrl+C!!!!')
if board is not None:
board.reset()
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
# create a PyMata instance
board = PyMata("/dev/ttyACM0")
# set pin modes
# set the pin to light the green led
board.set_pin_mode(GREEN_LED, board.OUTPUT, board.DIGITAL)
# set the pin to receive button presses
board.set_pin_mode(PUSH_BUTTON, board.INPUT, board.DIGITAL)
# arm the digital latch to detect when the button is pressed
board.set_digital_latch(PUSH_BUTTON, board.DIGITAL_LATCH_HIGH, cb_push_button)
