GUN4IR - The Ultimate 4 Points Lightgun System

<< < (3/195) > >>

JayBee:
Good news, thanks to Howard_Casto and his Mamehooker software, I was able implement mame output with my lightgun. I can send recoil, rumble and led control and parameters directly to the guns for each game independently.
For the games/emulators that support output, the solenoid, rumble motor or led that you have installed in your gun will react like in the real arcade machine.
It will also be very easy to customize.
And since it's switching the games automatically, for games that don't support output, the recoil, rumble and led will go back to be controlled by the Arduino.

This is very close to complete!
Next, I will add a way of checking the solenoid temperature with a small chipset, to modify its speed of actuation if getting too hot, and avoid frying it.
It could also allow you to continue to fire in full auto but with reduced speed as long as the solenoid is hot.

You got it done before I even had a chance to sit down and work on it.   :afro:

What type of interface did you use?

One thing I would suggest would be to add a pulse mode to your code.....  99% of the mame and model 2 library pulse the output for you with games like terminator 2, ect., but If I remember correctly Operation Wolf just has a steady on when the gun is firing.  It has to do with the mechanical operation of the guns... (op wolf and a couple others use a motor spinning a piston instead of a solenoid).  I have the outputs mapped for the model 2 emulator and some of the pc/techno parrot stuff as well, but I haven't released an updated troubleshooter 2 yet.

It wasn't so hard, your tool makes things so much more simple :cheers:

I'm using your serial write command to send combinations of characters and numbers, and read the serial buffer in the arduino. I'm really happy with the way it works, reading the serial buffer is very fast and doesn't add much latency to the overall execution.
Plus I am also sending special commands to completely control the behavior of the gun, meaning I won't have to change any settings manually anymore.

For the pulse mode, I already have one (king of) in my arduino code, it automatically starts full auto mode when holding the trigger button. I can also trigger it with a serial command, so it should be easy :D

The only issue I have is with games that have a variable speed pulsed command like terminator 2.
In my arduino code, I read the serial buffer every 3~5ms, and I also rely on specific timing for the solenoid holding and the minimum pause between each trigger (to avoid it to overheat). So the code detects the pulse command within 3~5ms, and then triggers the solenoid only if it's ready to be triggered. It means the game pulse and the solenoid pulse are getting totally out of sync.
Still scratching my head trying to find an elegant solution for that  ???

Yeah I didn't test the m2emulator outputs yet, but I will sure do it, would love some good Virtua Cop with accurate recoil!

Howard_Casto:
Honestly getting m2emulator ready to run with mamehooker is a giant pain in the butt, mostly because I'm getting it to do something it isn't supposed to do.  I'm working on it though. 

Yeah getting the pulse synced up is an issue.  Wait commands can be used to hold the solenoid open a bit longer so things can be slowed down somewhat, but that's about it.  I guess finding a solenoid that fires at the same rate as some of the positional guns would be the ideal solution, but I don't know how hard that would be.
