picbasic +12c508a+soft_stack error

[omid_juve]

it a program for 24v to 12v converter that has 3 input 1.over temperature 2.low input 3.overload and we have 3 output that 2 of them is just indicator and one (outputpin)
is the output for controlling the output voltage according to the situation of inputs.
and just the modes that you saw in the program can occur .
thanks for all of your help. my problem is solved .

You know what that means RIGHT?
Yup, this ain't over yet!

yup.. sounds like a challenge... 100% PBP??? Maybe doable... scratch, scratch...mmm...

12C508A's bad enough,
you want 100% PBP??? too?

Did you know it doesn't even have an overflow flag on timer0?
I didn't, Oi vey!

I had so much fun this time last year with what ended up as the 12-byte cylon scanner,
perhaps I'm a bit over zealous.

The OP is satisfied, and probably wouldn't use it anyways,
So even if the program size was only 83 words, like I have it now,
It'll never be used.

We need a real Optimization contest.
They're just too fun.

yup, no eeprom either... so nothing interesting. Think it's like a 16F84A, 16C54... but in 8 pin package

There's always place for an optimization contest, next time, no rules (pic, language etc etc )... agreed?

Make it tough...use a 10F200...no SOT->DIP adapters allowed, only hand soldering, dead bug style. In fact, no soldering, hand wrap wires around the legs....
and no power supply, hand crank a motor to charge up a cap...

Any chance we can see that 12-byte cylon scanner?

[Darrel Taylor]

Sure,

The 12-byte version is toward the end on page 2.

Edit: Hey, you were there to.

Yipes I totally forgot that one. That was way interesting and the end result was really creative.

Nice work DT..;o}

Tim B and I got into one of these a long time back, and here's one he came up with.

Can we beat this without EEPROM?

Standard cyclone thingie moving the LED back & forth with ~1S delay periods.
