I am working on a project.· I am a vol firemen and i am trying to use hte BS2e to be my flash pack for my leds that i am making.· My only problem is that i had wrote some code for the BS2e and my hd crashed and lost the code i need to some how get it from the stamp.· I also need to figure out how to have one have a mometary swith on it so when i hit it it changes flash patterns.· Any help would be great.· I wrote most of the code in binary so i could flash more than one pin at a time.· Is there and easier way?
Thanks
Mike

    so from what i read i have pretty much lost the code.· Well can someone give me some sample code for flashing pins 1 or more at a time and easy way?
    thanks

    Download our "StampWorks" book and look at the experiment having to do with simple lighting control (LEDs are used at the output) -- this is just the ticket for what you're wanting to do.

    can you show me the code in binary to turn on pins 0-3 and i did not use the flash pattern. And give you give me the differnt wasy that ican flash the leds. I really wish i had my other code.

    I'm a better code writer than mind reader, and since you didn't give me very much information I'm hoping this is what you want.

    Reset:
    · DIRA = %1111

    Main:
    · FOR OUTA = %0000 TO %1111
    ··· PAUSE 1000
    · NEXT
    · GOTO Main

    This displays binary values, %0000 to %1111 on P0..P3, with a one-second delay between changes.· If this isn't what you're looking for then you'll have to be much more SPECIFIC, going so far as to spelling out the sequence you want, e.g.,

    1 - 0000
    2 - 1001
    3 - 0110
    -- back to #1

    As far as different ways to flash the LEDs, I suggested StampWorks earlier because it has an excellent example (even if I do say so myself) of presenting different patterns on LEDs.

    I dont remeber using that command i jsut remeber the paus thing. But i think i had to set a delay and a pause. I htink i had it so i can tell it how long to keep the led on and how long to keep it off.
    I dont know what the command was bfore the binary
    %0000000001
    I think had something here not sure
    %0000000010

    basicly what ineed to do is i am trying to make flash patterns for these leds i have made for my car. so i will need to lets say flash pin 0 and pin 2 at the same time then flip to pin 1 and to pin 3. I dont knowif you are familer with strobe patterns on a police car. I am basicly making whats on the police cars and fire trucks. I jsut need to make the flash back with the BS2e
    Thanks

    Thats easy, and he pretty much did it for you. You just have to tailor what he did to your situation.


    ' {$STAMP BS2}
' {$PBASIC 2.5}

Led1          PIN     0                       ' Led1
Led2          PIN     1                       ' Led2
Led3          PIN     2                       ' Led3
Led4          PIN     3                       ' Led4


Main:

DO
     LOW  Led2       'turns Led2 off
     LOW  Led4       'turns Led4 off
     HIGH Led1        'turns Led1 on
     HIGH Led3        'turns Led3 on
     PAUSE 2000      ' waits 2 seconds

     HIGH Led2         'turns Led2 on
     HIGH Led4         'turns Led4 on
     LOW  Led1         'turns Led1 off
     LOW  Led3         'turns Led3 off
     PAUSE 2000       ' waits 2 seconds

LOOP                       'repeats untill BS2 is turned off.




    This is about as simple as it gets.

    Here's a very simple program I wrote that duplicates the pattern of a police light bar that I saw in my neighborhood near Dallas, TX.

    ok thanks for that i am not sure what you have set up in that text. I dont understand the code. Whats this temp stuff. BPM But is that turn the two leds on at the same time?
    thanks

    If you'll take just a few minutes to study the program you'll see that I'm storing the pattern of the police lights in a table. By using a table and a small "engine" to drive the table the program is much more efficient and ultimately easier to update.

    do you have any intro reading on the basic stamp?
    I am new to it all as you cant tell
    thanks

    TONS. My suggestion is that you download and read our "What's A Microcontroller?" book -- it's an easy read and will get your confidence in Stamp programming built in a very big hurry. About the time you're done with that StampWorks 2.0 (my book) will be out and you can use it to learn "pro" techniques to make your programs really fly.

    would thisw work so i could change form flash pattern to flash pattern
    FLASH:
    HIGH 0
    PAUSE 500
    LOW 0
    PAUSE 500
    HIGH 2
    PAUSE 500
    LOW 2

    HIGH 1
    PAUSE 500
    LOW 1
    HIGH 3
    PAUSE 500
    LOW 3
    IF IN5 = 0 THEN FLASH:
    IF IN5 = 1 THEN DOUBLE:


    Double:
    HIGH 0
    PAUSE 800
    LOW 0
    PAUSE 500
    HIGH 2
    PAUSE 800
    LOW 2

    HIGH 1
    PAUSE 800
    LOW 1
    HIGH 3
    PAUSE 800
    LOW 3
    IF IN5 = 0 THEN DOUBLE:
    IF IN5 = 1 THEN TRIPLE:

    Yes, the best way to start understanding the stamp, is to hook it up and try it out.

    Definetly read the WAM... I would do that first before trying to program the BS2
