Picaxe 14m Rapid Fire Mod, Utilizes A,B,X,Y,RB,RSclick,RTrigger Options

[killer skittle]

i used it, i think because with the SIMPLE code that was used! like without it sometimes the button gets "pressed" sometimes not, more for the consistency i think! thx for bumping i need to finish my video i have, this thing is GRAVY BABY! my next attempt after doing this one will be...da da da.....:

control EVERY input on the xbox controller, a hardware bot!!!

Yes, I've been waitting for the video before I go and try this. I would like to see it in action.

That doesn't really make sense as a reason.

Also, why such a huge chip? Why not a 16F84A or something

You need 15 digital signals to replace the buttons and 6 analog for the potentiometers. The 16F84A is a good chip but will require some sort of external DAC or digital potentiometer for the analog signals (SPI interface requires 4 pins). At 19 digital pins I think the 16F84A would be short by a pin or two.

The 16F887 can apply three pins per analog control using a resistor network, voltage divider or op-amp adder to provide up, rest, and down voltages. Using this method would require 15 + 3 * 6 = 33 pins. You may have an extra couple of pins left over to flash LEDs and stuff.

40 pins would be a massive dead bug to try and solder into a controller ... unlikely it would work for long before something fell off. if it were me I'd just buy an Arduino ($25) and build an interface cable using an IDE cable and connectors.

You don't need the darlington array. My understanding is that the push-buttons for this controller should be toggled between tri-state and ground. You do this by programming a pin for input with the pull-up resistor disabled (high) or as an output at logic zero (low).

Is your code doing this? It appears you are sending high as an output with logic 1 at +3 volts. Your diagram doesn't show the voltage source so I'm not sure. If so then your circuit may work fine or it may burn out the MCU.

The darlington driver chip will just overpower anything else including the MCU and pic-axe, and probably has protection circuits, like clamping diodes and stuff so that when you mis-use the electronics then it wins or protects itself.

Hazer in the Microchip forum has gone over this stuff quite a bit. I'll try to find a link for you.

I know very little about Picaxe programming but reading is the only place to start. I read a bunch of posts by Dr Acula about preserving pin states while others are doing output, etc. I still dont understand it all, but enough to get what youve seen so far to work.

Im still reading the rest....

If you want to know what is going on then read this thread in the Microchip forum:

http://www.microchip.com/forums/tm.aspx?m=353574&mpage=1

The key contributor is Hazer. He starts his posts on page 11:

For those just wanting answers then don't bother following these links. There is a lot of reading and you'll just get frustrated. If you want to understand how the rapid-fire code works then this is the best reference I have found to date. Just read all of Hazer's posts. The only wierdness is that Hazer wants to use opto-couplers for the matrix ... regardless, his rapid-fire assembly code has been copied all over the place.

I know i hate digging up old topics too...but it seems to be relevant...in terms of rapid fire and button glitches. This is the best way to go if you want FUTURE PROOF modded controller! easy code to learn and up to 7 button you can control.....ive had this controller since the halo 2 days with double shot lol and now im using it for the "jitter" mw2 glitch!

Hey skittle I would like to work with mods like this. I have a few ideas for a couple of buttons, and yeah the auto m16 is what I'm all about lol.

I'm pretty sure I can find better places for the chips. I need to get these chips, is your code open source? I have a pickit2 programmer

This is the source code for, drop shot button combo, full auto m16, and perfect timing grenade...if you have the same setup as i do.
im willing to help people out with this project as i have made four of these controllers lol

Hello Everyone. I've been doing a lot of reading round the forums... Great place, but I do have some questions.

I have noticed that this is the only sitcky that has a pic wired to all of the buttons, is that because this mod is too tedious to program?

How is this mod turned on and off, a seperate push button or is this a stealth mod?

Is or isnt the darlington array required? I would assume not as it was already mentioned in this topic, but I would like to make sure before I start a mod like this.



I am sorry for bringing up a dead topic, but I felt that this would be the best way to ask my question.
