Hi,
You say that if the button is pressed one time it should run the first loop - no problem there. But how fast should you need "double-click" or "tripple-click" it in order to run the second or third loop instead of the first one? Or should it run the first loop as soon as it sees a button press and THEN wait for the button the be pressed again?

With the count command but you need to understand that it counts for a certain amount of time during which nothing else will get executed, once that time has passed (10000ms in your case) the code will continue.

So, your idea was on the right track but the implementation had a couple of problems as explained in my previous message. Here's ONE aproach to the single, double, triple-click solution but remember that it might not work in reallity due to the switch bouncing as described before.

Let's say your button pulls the input low when pushed.

B_P_C VAR BYTE

WaitForButton:
  If GPIO.5 = 1 THEN GOTO WaitForButton 'Button is not pressed, go back and check again
  PAUSE 10           			'Wait a little while for the contact bouncing to die

WaitForRelease:
  If GPIO = 0 THEN GOTO WaitForRelease  'Loop here until button is relased

  COUNT GPIO.5, 1000, B_P_C             'Count number of presses for during one second

  IF B_P_C = 0 THEN GOTO FirstLoop      'Remember, we had to press the button once to get here.
  If B_P_C = 1 THEN GOTO SecondLoop
  If B_P_C = 2 THEN GOTO ThirdLoop      'First one press, then two more as counted by the COUNT-command.

Goto WaitForButton                      'Start over if number of presses is more than 3

FirstLoop:
'Your code here
Goto WaitForButton

SecondLoop
'Your code here
Goto WaitForButton

ThirdLoop:
'Your code here
Goto WaitForButton

END

Now, wire it up, compile the code, program the chip and GIVE IT A TRY! ;-) If there's still "basic" stuff that you don't understand then you need to back up and get that sorted first or you will just be creating more problems for yourself. Perhaps we jumped to the LOOKUP and COUNT commands etc a little too soon(?).

Henrik first of all a big thank you for giving your time to help me along (and everyone else too of course).

I agree, I do need to back up and go over some of the basics we've covered, like you say running before you can walk with programming will only compound problems later on.

I think I need to write lots of short programs using the basics and do enough of them to really drive it home.

That said, I do understand the basic principle of the COUNT command and it's timing component also with the LOOKUP command.

When you think that trying to use C and assembler I hadn't even managed to switch an LED on! I've come a long since joining this forum and using PB in the last few weeks thanks to you all, there's absolutely no doubt that this in the language to use!

So no, time to build this circuit (I need to make something work) and I'm sure I'll still have plenty of questions for you about the basics still, so you're not of the hook quite yet....;-)

No problems, we're all here to help.

Hi everyone.

I haven't posted for a wee while but have been busy reading and building my first two circuits.

The first is a 12F683 driving four LED's in a binary pattern 0-9 as per the thread (I've also added a nice little Night_Rider effect). I must say, although simple in what I've achieved, when those four LED's run up that binary pattern it was a real thrill, amazing.

The second circuit marrying the binary counting PIC to the BCD decoder driver then seven segment display is about half way built ( I'm quietly confident about this one fingers x'd).

Once again, thanks for all your help on here. I really wouldn't have got this far without it.

I'll be back when the second circuit is completed (early part of next week).

Hope you're all keeping well.

Hi Everyone.

Just to let you know I've got a a working circuit!!!!! Yippee.

It's a 12F683 into a SN74LS47N display driver and a 1" seven segment display counting up to nine.The PIC output also switches four transistors with collector LED's for a binary output count as well.

Simple stuff for you boys I'm sure but I'm chuffed to bits right now.

Not sure where to go or what to do next (any ideas welcome).

Thanks for your help as ever.

COOL!!!! You are moving right along.

Here is an idea. Setup a hardware timmer to change the display once per second.

Hi mackrackit

Are we saying for example to use the trimmer pot on the PICkit1 to alter the display speed ADC? (ADCIN).

I'm seriously considering buying the the full program version by the way (I'm just trying to convince myself I'm clever enough to figure out how to use / make the most of it...lol).

Really enjoying it though (headaches aside ;-))
