nosix / raspberry-gpio-emulator Goto Github PK

Hi!
It seems to make the code running on Raspberry 3 B+ you should use GPIO.setmode(GPIO.BOARD) instead of GPIO.BCM. Pin 12 board pinout supports PWM.

Many thanks for the development of the project. It helps a lot if you don't have to work on the Pi all the time.

But is there a clean way, to stop the emulator and close the gui from the application and not per clicking the gui?
At this moment I have to interrupt the emulator per SIGINT or Keyboard Interrupt what leads to an error message.

Step:

• Run sample_input.py
• Keyboard interrupt (Ctrl-C)
• Process may remain

使用pip install future
添加builtins的支持后

Hello nosix,
thanks for sharing this useful GPIO simulation library!
In my program I want to first setup a pin as input (High-Z), and after a game is completed set it to output LOW. This works fine with the real RPi GPIO library. But with the emulator library, this error is thrown:

Traceback (most recent call last):
  File "./riddle_beer_dispenser.py", line 105, in <module>
    main()
  File "./riddle_beer_dispenser.py", line 92, in main
    GPIO.setup(solvedPin, GPIO.OUT, initial=GPIO.LOW)
  File "/home/dan/.local/lib/python3.8/site-packages/RPi/GPIO.py", line 159, in setup
    __setup(__to_channel(channel), state, initial, pull_up_down)
  File "/home/dan/.local/lib/python3.8/site-packages/RPi/GPIO.py", line 168, in __setup
    assert channel not in __pins_dict, 'GPIO is already setup'
AssertionError: GPIO is already setup

I think it should be possible to change the pin mode once more after initial setup. Can you please fix it?

Hi!

I am using the GPIO.add_event_detect with GPIO.BOARD setting.

The emulator in the callback gives the channel number instead of the pin number.

The documentation sais it is OK, but on the hardware the default GPIO library gives the pin number in this case!

The old code:
GPIO.add_event_detect(PINS.BUTTON, GPIO.BOTH, callback=waitOnEvent)
which gives the parameter like channel.

I use the folowing workaround:
GPIO.add_event_detect(PINS.BUTTON, GPIO.BOTH, callback=lambda x: waitOnEvent(PINS.BUTTON))
which gives the parameter like pin (PINS.BUTTON)

I dont know it is a problem or not, but definitely a compatible issue...

Hello, i'ad try to use it on windows 10 pro on docker stack and pip failed to install the numpy package.

I going to test with https://github.com/MomsFriendlyRobotCompany/fake_rpi
to see if i can manage RPi.GPIO emultion.

Hello, Great job !
Can we expect one day the package will be available on pypi.org?
