original quickshot joystick autofire frequency

[prezi]

Helo,


I just programmed atari-like joystick using arduino. It is equipped with autofire and I would like to set it up just like in original joystick. Could anyone check it out for me? Please.

Hello prezi,

which Quickshot model do you mean?

I just measured the autofire frequencies of 4 Joysticks for you. Cps means clicks per second.

Quickgun Turbo Pro:   7 cps
Zipstick:            13 cps
Quickshot 128F:      29 cps
Competition Pro:     62 cps (!)
(transparent model with autofire)

I wonder what is the best for many games. I think 9-16 is the most useful.

Hope that helps

PS: Do you want to share a picture of your project?

Up to now I have almost all parts (I have to buy them in many
different shops). Meanwhile I decided to program arduino micro.
When I finish the whole project I will share with you all pictures of that.
Joystick as such will be very similar to others so-called "arcade joystick with two buttons".


I attach the arduino code: besides it has rapidifre this is really "zero delay" joystick.

To be sure: by CPS do you mean faked button "clicks" (both press and release). If you do, it means that for instance if CPS is 29 then there is
14.5 "shots" per second.

Funny that the "turbo" one has the slowest autofire :-D What liars...

No, it means 29 shots per second.

The Comp Pro is ridiculously fast. I once checked the best autofire rate for River Raid Reloaded and it was about 15 cps.

At least it's a beauty (Google it)

Thank you very much!

I attach pictures and Arduino code.


Parts:
-enclosure Hammond HM-1591USBK
-joystick Sanwa JLF-TP-8YT
-GT-Y Octo Gate
-KOWAL 1mm Oversize Actuator
-2Kg spring from Focus Attack
-two non-original push buttons 30mm
-one LED Red Latching On/Off Switch (as rapidfire switch)
-one arduino clone ATMEGA 32U4 Arduino PRO MICRO
-some cables
-three pieces of wood
-4 threads + 4 screws (to attach joystick plate to wooden pieces)


Joystick is attached to wooden pieces because the enclosure is made of ABS so it's soft. And thanks to that there are no visible screws. In addition joystick is more stable and "heavy".


Both push button are connected together so there is actually just only "button A".


There are many diy projects like that but none of them has an autofire (rapidfire). In most of other projects some crappy "zero delay" encoder board are used. But they are not "zero delay". I bought one and I found that this is usb1.1 and the polling delay is at least 10ms. Just like for instance Competition Pro USB Joystick. In case of arduino projects everybody uses "delay" instruction to debounce joystick.

In attached Arduino code no "delay" instruction is used. Every pin is debounced separately by non-delay counter. Eg. for 10ms fire state cannot be changed but meanwhile you can change up-pin state.
Arduino ATMEGA 32U4 based boards have 1ms USB polling delay. State of pins is read about 50 times per millisecond so 1000hz usb polling rate is real.

edit: atari-like-rapidfire-led-interrupt.zip is a little bit faster and supports rapidfire without led

Nice Project prezi!
How well does it work when you test/use the Joystick?

[prezi]

just great. Actually I use it mostly with VICE (C64 emulator) and sometimes with FS-UAE. In VICE I play with my kids in Boulder Dash and running away from falling boulder is a piece of cake. In case of competition pro usb it was not so easy. In FS-UAE we play Prehistrorik and Dyna Blaster and that joy is very responsive. Making corners is very easy with sanwa -- thus jumping in Giana and Bruce Lee is easy.
