OPP & MPF serial problem on Mac

[Adrien A-G]

Hello everyone!

I'm new here. I'm trying to make a half scale pinball with (almost) all the fancy stuffs you find on full size pinball.

I'm using OPP and MPF (Both tremendous projects! I only discovered them recently) to drive it from Mac OS X at the moment (I would like to move to Raspberry Pi 3 further down the road). But I'm encountering a problem (I did search the forums but didn't find my answer…) making OPP and MPF communicate together. Maybe I did miss a simple step, has I am not really tech savvy concerning Terminal and Serial ports…

Here is my problem. When I build my MPF Machine (mpf -b) the program end with: 

AttributeError: module 'serial' has no attribute 'serial_for_url'

My OPP processor is flashed with the "Gen2.rev0.2.0.5" firmware and configured with "2sol2switch". The Mac is able to connect to it (and was used to flash it). My MPF config (derived from Step 3 of the Tutorial) is configured for the OPP hardware and the port is the right one at the time of my test. 

I don't get what I'm missing here, some configuration I did wrong or some Python I missed?

Here is my MPF config:

#config_version=4

hardware:

    platform: opp

    driverboards: gen2

opp:

    ports: /dev/cu.usbmodem146121

    baud: 115200

switches:

    s_left_flipper:

        number: 2-16

        tags: left_flipper

    s_right_flipper:

        number: 2-17

        tags: right_flipper

coils:

    c_flipper_left:

        number: 0-0

        allow_enable: yes

        hold_power: 2

    c_flipper_right:

        number: 0-1

        allow_enable: yes

        hold_power: 2

flippers:

    left_flipper:

        main_coil: c_flipper_left

        activation_switch: s_left_flipper

        enable_events: machine_reset_phase_3

    right_flipper:

        main_coil: c_flipper_right

        activation_switch: s_right_flipper

        enable_events: machine_reset_phase_3

Here is the Terminal extract:

If someone has an idea of what I may have done wrong, I'll be happy to ear it. :¬)

Thanks and take care!

That's a weird error. Can you post the output of "pip3 list"? It looks like pyserial is not installed properly or something. Looks not like a typical error with that lib.

Thank you Jan!

Here is the "pip3 list":

Thanks for the advice, I did uninstall and re-install pyserial for Python 3 and it seems to have changed something!

Now I have this error. It seems to be a problem with the input I designated in my config file but I don't know where. My configuration on the OPP is 2 solenoid (wing 0 and 1) and 2 inputs (wing 2 and 3) but input number seems to match in my MPF config file…

Thank you again for your help.

It looks like you only have one OPP in your system?  if so the numbering on your switch definitions is incorrect, they should likely be 0-16 and 0-17.  the 0 being the OPP board number, not the wing number, so if you only have 1 OPP board they would all start with 0

[Adrien A-G]

You are right! I have only one OPP processor currently. I read the documentation wrong…

Thank you so much to both of you for your help!
