OPP platform doesn't allow changing pulse width using pulse call

[Jeremy Wilson]

I'm finally at a state where I can test MPF on my game, and when I hit a drop target I get this and MPF crashes:

INFO : SwitchController : <<<<< switch: pfs_left_eject, State:1 >>>>>

ERROR : root : OPP platform doesn't allow changing pulse width using pulse call. Tried 10, used None

HI Jeremy,

Can you post the full log and maybe your full config?

[Jeremy Wilson]

Find my config attached.  I'm running the latest MPF 0.30 on RPi.

The switch in question is for an eject hole.

Hi Jeremy,

thanks for finding this! I fixed it in 0.30, 0.31 and 0.32(dev). We did not honor default_pulse_ms (10ms) in OPP when you did not specify a pulse_ms in your coil.
