Hi All,

 

I have been building a virtual pinball cabinet over the last few months and finally got the bugs ironed out in the build of my pinscape boards ( mostly solder joints ). Finally installed the knocker and it works fine apart from one odd thing. When I use the Pinscape Config tool to test the knocker and push the button to on nothing happens. When I turn the button off the knocker fires for the prescribed 2 seconds. Also when I program the KL25Z it works fine but on completion it fires the knocker.

 

It seems like I have some backward as it takes the 0V as the firing trigger instead of the +VE. I know LEDWiz does that but I am not using any of those boards just the pinscape main board plus one output board.

 

FYI - I have been using MJR's pinscape build guide which I think is AWESOME. Thank you sir for putting such a detailed guide together as you saved me much from a lot of stress and pain 

 

Any ideas would be much welcome

 

Cheers,

 

Ian.

I haven't wired up my knocker yet, but obviously power (I got a 48V supply just for this) should be applied to the red wire.  Did you add a diode?

Hi strells,

 

Thanks for the reply.

 

I have a 24 Volt PSU stepped up to 48 Volt with the red wire from the + on the output from the step up to the knocker. There is a diode between the input and output of the knocker oriented as per mjr's guide. The output from the knocker goes to the knocker on the pinscape main board.

 

Like I said it's not that it doesn't work - in fact it makes a perfect punch when it fires. The only thing I find odd is I was expecting it to fire once I switch it ON in the config tool. Nothing happens until I turn if OFF then it fires for 2 seconds before shutting down. Shouldn't this be the other way around?

 

Also seems a little odd that it fires after updating the KL25Z from the config tool.

 

May be it is supposed to do this - just wanted confirmation that it is normal.

 

Edit: Moved this question to the pinscape expansion boards thread.

 

Edit : problem solved. I had set the knocker output to active low in the config tool by accident. See the thread in pinscape expansion boards forum for details. Thanks to mjr and mikepiball.
