Make me some code..

[xobx]

This is my current circuit



Can you make a code like this (in PICBASIC PRO):

When you click the button a timer starts and when you push it again it stops, and after that the LED blinks with "your time"..


Can anyone do this?

My one and only serious Question ...

How much do you give for that ???

I'd pay money to have somebody write code just to turn that LED on... (never mind anything else - assuming it's a standard LED)...

Hi, Mel

That looks too much like the intelligent automobile screen wiper timer ...

I just want some example code to understand how the timer works, but i quess i haft to figure it out myself..

[RussMartin]

I may be wrong, but . . .

. . . I don't think that the LED will ever light up with any program!

...Can anyone do this?

I guess the consensus is: NO, nobody can, even if they were willing to do it.

As for this, there are an amazing number of examples for applications like this on the forum, as well as MeLabs own website, and the web in general.

I seriously doubt someone is going to be kind enough to write the code for you out of pure generosity and goodwill. That’s not to say no one will be helpful. Do a little research and come back with more specific questions. The help you reap will be proportional to effort you sow.

Hi,

Russ is right about the LED. You are showing it backwards. Steve B is right also. There are more than enough examples of timers, blinking LEDs, and start/stop programs on this forum that if you sat down and organized them all, you would have a book on beginning to work with PICs. If you are looking for the quick fix, it ain't happening here. We will all be glad to offer advice once you have made some effort to try programming. Also I think you should connect your push button to the ground side of the circuit and make the resistor a pullup instead of pull down. (Nothing personal just a preference. This way you won't have to program the pin in an extra step.)

Go to CODE EXAMPLES and SCHEMATICS to start your search.

Good luck. When you get stuck, then ask!

I can try. No timer use

DEFINE OSC 4
CMCON = 7
ADCON1 = 7
output PORTB.0
input PORTA.4
b0 var word
b0 = 0
HIGH PORTB.0
pause 200

main:   if PORTA.4 = 1 then enter
        goto main

enter:        if porta.4 = 1 then enter
            
tmecnt:    if PORTA.4 = 1 then extime
              b0 = b0+1         
               pause 100   ' Least count of time 100 ms
              goto tmecnt

extime:     if PORTA.4 = 1 then extime

ledon:  b0 = b0 * 100
        LOW PORTB.0
        pause b0
        HIGH PORTB.0
        b0 = 0
        goto main
        end

If code works, can i give my PayPal................ hehe

My challenge was to write a piece of code to make the LED in that schematic light... I can't see your code turning that LED on... never mind any timers or buttons, just simply illuminate the LED as wired in that schematic...

As someone who likes to learn new things, it's worth it to me to know how to accomplish this in software (PICBasic, Proton, Assembler, C, Fortran, Cobol, Algol, whatever, I'm good for all flavours)...

For those that want to take up the challenge... I'll save you some time and tell you that the piece of code below WON'T work...

High PortB.0

and neither will...

Low PortB.0

So... a US$10 challenge to the first person who lights the LED (a bog-standard, common or garden nothing special cheapo average LED) in that original schematic (which must remain unchanged) as shown in Post #1 above... and posts his or her working code in this thread...

It's a great challenge but I think it's worth more than $10! I'll add another $10 to the pot for the person who achieves it ;-). Now it's worth $20!

Oh. BobK is right.
LED will never illuminate according to circuit.

How about: 'accidentally' cut the wire directly above the "16F628" in the circuit diagram, then PORTA.4=0, then PORTB.0=1, and press the button. LED=lit!

I don't think this qualifies.
