New project help rapidfire on 12f683

[Darrel Taylor]

I've been working on an NKK display in another thread for what seems like a week (3 days). So I hadn't been paying much attention to this one.

After a quick review, the problem I see is that there are a lot of buttons on the 360 controller. It's most likely that the buttons are "Multiplexed".

In the PDF of the original project, it shows an input FROM the button, and an output TO the button. So apparently the pulses can only be put out when that button gets scanned.

This will be more difficult than just toggling a pin 3 times.

Do you have an oscillicope to verify if they're scanned or not?

well those are not buttons the middle one is the one that acually bings the low to fire the trigger the others are inputs and outputs dont know whih ones ill do some more research thanks!

Hey after playing around and some testing with my new multimeter I found out this, The top pin is always low or ground the middle pin is 1.41 volt When the trigger is not held down, But when you start pressing the trigger it slowly starts decreasing, the more you hold it down the less the voltage gets. When i held the trigger down all the way It was at 0.31-0.30 volts thats afcourse when its down all the the way but even if you press it a little bit the voltage will decrease a little bit and the bottem pin of the 3 is at 1.61 volt all the time and doesent decrease nor increase. This is afcourse on this version of the controller while the other fires off high but not low like this

this is cool
