PS2 viberation not working

[robotdude]

@Bane

Are there any modifications made to this controller?

bane

No modifications, it’s a genuine imitation PS2 games controller. 8)

[bane]

It’s possible that the second batch of controllers we received didn’t have this feature

Do you mean that you made the tutorial on a different brand controller? If so…that sux, i had a great idea for a robot.

Yes the original code was written for the MadCatz controller and also verified with the Sony brand one. I am working with the mfg to get some help. I don’t know if we will be successful but we are trying.

Sony will never release any code examples for the controllers. All of the code commands we are using were found on the internet a long time ago. They were posted by people who have attempted to reverse engineer it. We continue to fine tune and further modified the code to fix inaccuracies.

Because the motors work on the PS2 console then it’s just a matter of fine tuning our code to make it work. This is easier said then done.

[bane]

any luck?

is there anything i can do to help?

Nothing yet. With the language barrier, the competition, the Sony factor… I will prod them again.

question: why do you have the green connected to VS in this picture? http://www.lynxmotion.com/images/assembly/eh3rv2/big/eh3r12b.jpg

Can i get a controller that will work or should i hunt for one of those good old controlles .

Bane

[robotdude]

The green wire is used on some controllers for the vibrating motors. However on the Lynxmotion ones the wire is not used.

[bane]

Over the week end i got the viberation motors to work with this code:

However, i can’t get control of any bottons or the d pad. Only have limited control of right and left joys.

please help, i’ve tried a lot of things and i just can’t seem to get viberation and full control all at once!

I asked Laurent to look at your code to see if you may have found something here.

[laureatus]

Hey Bane ! you found something,

using “old” PS2 DualShock 1 mode ($73) makes the Lynxmotion Pad to be able to vibrate .

so, here’s some explanations about your program which was not working :

• Temp( 7 ) and temp( 8 ) were not read, so they were filled with random values
• using for-next loop is too slow to read PS2 flow, so we must read all data within a line
• “large” and “small” variables were inverted in the “shiftout” line, the first one to be sent is “small” then “large”

some pauses are added
temp array is reduced to 7 bytes
temp1 and cntr variables deleted

please note :
using DS1 mode ($73), all buttons are numeric, no more analog.
so here’s the corrected code (SEL and CLK lines were swapped to see pin assignment incremental)

Thanks for your help solving this

[code]; PS2 Controller Program for BB1/BB2
; PS2 mode $73, Dualshock 1 mode, compatible with DS1 and DS2 PAD
; 16 numeric buttons and 2 X 2 axis analog joysticks
; vibration compatible with PS2 Lynxmotion controller
;
; push right arrow to enable the small vibration motor (only “on” or “off”)
;
; push left arrow to allow the large vibration motor, keep pressed
; then move the right joystick vertically to control the large motor speed

[bane]

Yes! It’s about time things start working on my project .

some pauses are added
temp array is reduced to 7 bytes
temp1 and cntr variables deleted

Are you saying that its not possable to have temp array to 19 bytes (full capasity of controller)?

If not, can i just make the modification to the code that the viberation doesn’t work on?

Thanks for helping me out on this, i spent quite a bit of time fooling around with the code (with no clue what i’m doing ), I’m still a noob at all this advanced basic coding.

Bane

[robotdude]

I think he just reduced it to the minimum required for the purpose. You can increase it if necessary.

[laureatus]

Bytes 8 to 19 were analog buttons positions…as Dualshock 1 mode ($73)
doesn’t handle analog buttons you just need 7 bytes.

DS1 mode uses 16 numeric buttons and 2 X 2 axis analog joysticks

using DS2 mode ($79 as before) will allow analog buttons but will not allow the vibration on the Lynxmotion PS2 Pad.

Anyway, none of the projects is using analog buttons for now.

[bane]

Laureatus, have you ever had a problem with the PS2 data repeating commands? Thats what mine is doing, heres an example:

[code]…
IF temp(8) <128 then
goto walkforward
elseif temp(8) > 128
goto walkbackward
endif
…

[/code]
What will happen is then temp(8) meets one of those conditions it repeats the what ever is after the condition twice.

Any Ideas?

Bane

[laureatus]

I’m not sure to understand,

if you mean your robot is performing “walkforward” and “walkbackward” at the same time…

it’s false…and true
let me explain,
it’s false in the fact that your code is correct, so it can’t perform both “goto” in the same loop.
So, looking at this small part of code we could think all is correct.

But :

Your program is looping on itself i suppose, so this code is called many times per second, this is where problems starts.

the PS2 controller is not so accurate, it goes both side of the 128 value many times per seconds even if you don’t move it
so it’s true in the fact that both “goto” are called within a second, each different one in a different “main” loop.

that’s why you should add a “Deadzone” 8)

in fact you already have programmed a “Deadzone”, because if the value is 128, none of the “goto” are called because you are using “> 128” and “< 128” (strictly < or >), but this is too small range.

try this :

IF temp(8) < 115 then goto walkforward elseif temp(8) > 141 goto walkbackward endif

now the “Deadzone” width is 27 values, this is a good range for most of the controllers

[bane]

Let me make this clearer on whats happening.
I’ve tested a few things to make sure that this is happening all my TEMP variables.
Example.

If temp(13) > 228 then sound 9, [50\5000] pause 500 endif
Take this simple code for an example. If temp(13) is greater than it should play the tone once and continue with the program, which it does only instead of playing it once it playes it twice. Now i’ve added the pause there so that it doesn’t have a timing issue. But even with the pause (if i press one button quickly) that should be enough time for temp(13) to equal 0 again.

What my thoughts are on this is that the somehow the shiftin is repeating data twice for some reason. I think that if there was if a filter could possibly be applied to Temp(byte). For instance, If temp(8) > 115 then let temp(8) equal what ever number it is but only for 10 mS or something.

Heres (prehaps)another solution

[code]if temp(8) > 115 then
randomvar = 1
elseif temp(8) < 141 then
randomvar = 2
endif

if randomvar = 1 then
gosub walkforward
randomvar = 0
elseif randomvar = 2
gosub walkbackward
randomvar = 0
endif[/code]

This way regardless of how many times temp(8) value repeats its still only going to do the intended command once

BTW thanks for all your help

Bane

[laureatus]

Oh !

I’ve never heard this one, anyway, the problem is not in this part of the code.

so, first, you’re not using vibration with this code uh ? because temp( 8 ) and temp ( 13 ) are not used in the “vibration” code for lynxmotion PS2 pad…just to check

You should try to use a bigger pause for the test, like “pause 2000”
if it does the same, try this

If temp(13) > 228 then temp(13) = 0 sound 9, [50\5000] pause 2000 endif

if it’s still not working add a “pause 30” just after the “main” label that you loop on (i suppose), the PS2 pad can’t be asked for new data too often anyway…

if it’s still not working, please post the whole program (the shortest “non working” version please)
i will take a look…

Nope, it still repeats it. Can you try it on yours?

Bane

[laureatus]

Here’s some mods,

the datas are not duplicated, i was able to make it beep once with the original program, when it beep twice or more, the temp(6) variable is always different but < or > to the threshold value.

i have corrected some issue in the code, the temp bytes table must be defined to temp( 19 ) rather than 18
temp( 19 ) means 19 bytes from temp( 0 ) to temp( 18 ), this way you’re not overwritting the next variable stored in memory after the temp bytes table when using shiftin.

anyway here’s the code corrected, but i’m not sure it’s the way to go
this way the WalkForward code will be called only one time if the joystick is pushed up…then to call it again you’ll have to release the joystick then push it again.

“normal” behavior should be to define a WalkForward code to move one step then return to main loop, then if the joystick is still pushed up it calls again the WalkForward code and move one step more etc…

I’m not understanding how you will define the Walkforward code the way you do.
see the next post for another way…

If i was misunderstanding and if the only problem was that you wanted only one call for a quick joystick push up, but more calls if the joystick is keep pressed up (or down)

in this one , only the pause after the main loop is increase to 100, you can increase it more if you want…

as your program will grow, you’ll have to decrease this pause, because your program will take more time to loop.
