That's maybe a misunderstanding of the Pingo API from my side.
My goal is to have a led on to show user that software is running correctly.
At switch press, led should be blinking foreever (recording a video with picamera module).
At next switch press, led should stop blinking and be on (like before first blinking).
After an other switch press, led should be blinking foreever ... and so on...
I did this:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import atexit
from time import sleep
#import RPi.GPIO as GPIO
import pingo
from pingo.parts.led import Led
from pingo.parts.button import Switch
import time
class App(object):
def __init__(self):
#GPIO.setwarnings(False)
self.board = pingo.detect.get_board()
led_pin = self.board.pins[13]
self.led = Led(led_pin)
self.btn_pin = self.board.pins[7]
self.switch = Switch(self.btn_pin)
self.switch.set_callback_up(self.toggle)
self.recording = False
def loop(self):
self.init_led_and_switch()
try:
while(True):
time.sleep(1)
except KeyboardInterrupt:
print("User Cancelled (Ctrl C)")
self.stop_at_exit()
def toggle(self):
print("press")
self.recording = not self.recording
if self.recording:
self.led.blink(times=0, on_delay=0.8, off_delay=0.2) # blink foreever
self.start_recording()
else:
self.led.stop() # stop blinking
self.led.on() # doesn't seem to work as expected!!!!
self.stop_recording()
def init_led_and_switch(self):
self.led.on()
self.switch.start()
def start_recording(self):
print("start recording")
def stop_recording(self):
print("stop recording")
def stop_at_exit(self):
self.led.off()
self.switch.stop()
self.led.stop()
self.board.cleanup()
def main():
#atexit.register(GPIO.cleanup)
myapp = App()
myapp.loop()
if __name__ == "__main__":
main()
Hello,
I noticed a strange behavior with blinking led.
That's maybe a misunderstanding of the Pingo API from my side.
My goal is to have a led on to show user that software is running correctly. At switch press, led should be blinking foreever (recording a video with picamera module). At next switch press, led should stop blinking and be on (like before first blinking). After an other switch press, led should be blinking foreever ... and so on...
I did this:
Any idea ?
Kind regards
