Example of how to use the Touch class of the Machine module:
from machine import Touch
from machine import Timer
import time
class TouchPad:
def __init__(self, pin, name):
self.touch = Touch(pin)
self.last_press = 0
self.name = name
self.pressed = False
def ispressed(self):
if self.touch.read() < (self.touch.init_value() * 2 / 3):
self.pressed = True
else:
self.pressed = False
return self.pressed
def just_pressed(self):
now = time.ticks_ms()
if now - self.last_press < 500:
return True
else:
return False
def set_press(self):
self.last_press = time.ticks_ms()
class TouchController:
def __init__(self, pads):
self.pads = pads
for pad in self.pads:
pad.touch.init_value(1500)
def check(self, alarm):
for pad in self.pads:
if pad.ispressed() and not pad.just_pressed():
pad.set_press()
if pad.name == 'Right':
if tleft.just_pressed():
print('Swipe right')
else:
print('{} pressed'.format(pad.name))
elif pad.name == 'Left':
if tright.just_pressed():
print('Swipe left')
else:
print('{} pressed'.format(pad.name))
elif pad.name == 'Up':
if tbott.just_pressed():
print('Swipe up')
else:
print('{} pressed'.format(pad.name))
elif pad.name == 'Bottom':
if tupp.just_pressed():
print('Swipe down')
else:
print('{} pressed'.format(pad.name))
tleft = TouchPad('P4', 'Left')
tright = TouchPad('P8', 'Right')
tbott = TouchPad('P9', 'Bottom')
tupp = TouchPad('P23', 'Up')
# initialize the touch controller
touch_controller = TouchController(pads=[tleft, tright, tbott, tupp])
# enable the alarm to check the status
Timer.Alarm(touch_controller.check, ms=10, periodic=True)
