示例1: Ultrasonic
# 需要导入模块: from machine import Pin [as 别名]
# 或者: from machine.Pin import on [as 别名]
class Ultrasonic(object):
def __init__(self, trigger_pin, echo_pin, timeout_us=30000):
# WARNING: Don't use PA4-X5 or PA5-X6 as echo pin without a 1k resistor
# Default timeout is a bit more than the HC-SR04 max distance (400 cm):
# 400 cm * 29 us/cm (speed of sound ~340 m/s) * 2 (round-trip)
self.timeout = timeout_us
# Init trigger pin (out)
self.trigger = Pin(trigger_pin, mode=Pin.OUT, pull=None)
self.trigger.off()
# Init echo pin (in)
self.echo = Pin(echo_pin, mode=Pin.IN, pull=None)
def distance_in_inches(self):
return (self.distance_in_cm() * 0.3937)
def distance_in_cm(self):
# Send a 10us pulse
self.trigger.on()
sleep_us(10)
self.trigger.off()
# Wait for the pulse and calc its duration
time_pulse = time_pulse_us(self.echo, 1, self.timeout)
if time_pulse < 0:
raise MeasurementTimeout(self.timeout)
# Divide the duration of the pulse by 2 (round-trip) and then divide it
# by 29 us/cm (speed of sound = ~340 m/s)
return (time_pulse / 2) / 29示例2: Pin
# 需要导入模块: from machine import Pin [as 别名]
# 或者: from machine.Pin import on [as 别名]
# NeoPixelをいくつか（1セグ４個くらい）つないで７セグにし、大会用のタイマーにする。
# 7セグのaからbcdefgと順番に信号線で一直列につなぐ。7セグ１桁のタイマー。
# 残10分から表示し、時間ぎれで点滅＋ブザー鳴らす。
