My Hover Craft

edited 2005-12-17 09:49 in General Discussion
I have the idea to make a hovercraft run via the w, a, s, d keys how can I do this w/o debugin or even with it but so i can continuesly read the key. If i leave it how it is then i push the w key once and the BS2 stamp just keeps transmitting via the hacked hovercraft controller. Can somebody please post their code on how to do this because my 1st attempt made the moters kinda pulse then the 2nd attempt made the motor go until the hovercraft was turned off and reset pushed. I would like to run of the key board because if I make some kind of controller that defeats the purpose of the project.

    What Im trying to say is i need to continuessly read the keyboard eg.
    W
    a s d

    W being the one pressed Debugin should write the value of W to a Varialble caller user but once i push that either A it stops after a few milliseconds regardless of me finishing pushing or not then it will loop creating the pulse effect and that is no good. Or B i push the button once and it goes forever. Either A I need a new command for my BS2 to read from the keyboard or B Im doing something wrong about the way im useing it. I've attached code if that helps:
    ' {$STAMP BS2}
' {$PBASIC 2.5}


LeftF       PIN      12
LeftR       PIN      13
RightF      PIN      14
RightR      PIN      15
user        VAR      Byte(1)

'System Test Initiating...

'HIGH LeftF
'PAUSE 2000
'LOW LeftF

'System Check Finished

DO

  DEBUGIN STR user\1\1

  ' Forward = W
  IF (user = "w") THEN

    HIGH LeftF
    HIGH RightF
    PAUSE 250
    LOW LeftF
    LOW RightF

  ENDIF

  ' Brake = S
  IF (user = "s") THEN

    HIGH LeftR
    HIGH RightR
    PAUSE 250
    LOW LeftR
    LOW RightR

  ENDIF

  ' Left = A
  IF (user = "a") THEN

    HIGH LeftF
    HIGH RightR
    PAUSE 500
    LOW LeftF
    LOW RightR

  ENDIF

  ' Right = D
  IF (user = "d") THEN

    HIGH LeftR
    HIGH RightF
    PAUSE 500
    LOW LeftR
    LOW RightF

  ENDIF

LOOP

    Are you using a keyboard directly attached to the BASIC STAMP? Are you connected through the parallel port, USB, or RS-232 port, or something else?

    FYI the code I posted earlyer was the actual code for step one eyes.gif And just the normal serial port that you would program the stamp with BTW not the USB the other one on the back of the computer

    I would use a program that listens for data on a serial or parallel port. If you want the basic stamp to listen for serial data directly off the port you need to use the serin or debugin statement. That can get messy so I just use the parallel port. Write a program that sets a certain bit in the parallel port when a key is pressed and clears it when you release the key (Use C or Basic or something). Program the basic stamp to react when that bit is high. Use LED's to test to see if the stamp is responding appropiately to your keyboard input before you go directly to hovercraft control.

    kingneb,
    Microman171 is using the DEBUGIN (which is a specialized form of SERIN) command to accept input from the computer.

    Microman171,
    What you are looking for would probably be a good candidate for a "state machine" style of code. This has been covered before on this forum. With your current program, the Stamp "interprets" the key, and "moves a little" then looks for another key. If you want the craft to keep going, don't turn off the motors (the LOW commands in your code) until they need to be turned off...

    You need to create a visual basic program that sends data to the stamp. I'm at school right now but when i get home i'll try to post something

    Hello,

    Have you heard of visual basic.NET? Visual Basic 5 and 6 are obsolete but still used. Worse yet, they are not availible anymore or fully supported. VB.NET has a serial port class build directly into it. If you are not familiar with object oriented programming, learning it is not hard. All you need is those nutshell style tutorials you can find with google searches, not those big fat books you get at borders. nono.gif Too much jargon and too expensive, no bang for buck, LOL. The Beta 2 Visual Basic 2005 is available for free here:

    lab.msdn.microsoft.com/express/vbasic/default.aspx

    I wish you the best of luck smile.gif

    The best way to go is to write your own code with Visual Basic.NET It is well documented and very easy to learn. It should handle serial communications just fine.

    For the basic stamp please use LEDs as logic indicators to see if the stamp is responding correctly to your keyboard transmission. For example, you hit the W key. The response is sketchy, sometimes it lights and other times it does not light or light immediately. That problem is a timing issue. That maybe what you are having.

    See if this works (this assumes you have LEDs connected to pins 0 through 3):

    
user var byte(1)

start:

debugin STR user\1\1

if (user = "w") then
     high 0
     low 1
     low 2
     low 3
     goto start
endif

if (user = "s") then
     low 0
     low 1
     low 2
     high 3
     goto start
endif

if (user = "a") then
     low 0
     high 1
     low 2
     low 3
     goto start
endif

if (user = "d") then
     low 0
     low 1
     high 2
     low 3
     goto start
endif

goto start



    Post any problems with logic indication.

    Try the BS2 code I posted previously and setup I recommended. Try playing with that a bit. If I give you VB code you will have the same problem because the "exact same" serial data will be sent from the VB program that the Stamp editor debug utility sends. The data keeps getting sent on an infinate loop because you did not program the stamp to handle it correctly.

    Did you try to analyze the reason why it is doing that? I had a problem with the debug command doing that once. I sent data in parallel to the right pins on the basic stamp. I fugured it out because I forgot to add a line of code that redirected the data handling when a signal changed.
