odd 2550 behaviour

[Raflex]

I mistyped this in a program ( I quickly wanted to blink an LED on portA)

high porta.1
pause 500
high porta.0
pause 500
high porta.1
pause 500
high porta.0
pause 500
high porta.1
pause 500
high porta.0
pause 500

See the problem, they all should be portA.0, so in theory the LED on PortA.1 should light, slight pause, then the LED on PortA.0 should light.

Ha, no it doesnt, well OK it does BUT the first led (on PortA.1) goes out, and instead of 2 leds being on, I get alternating leds ????

Ie

01
10
01
10

I expected

01
11


(edit)

'alldigital' fixed it so I must have one of those damn 'con' keywords wrong.....

You have a mistake, need to use low to turn off.

[f_lez]

Yes I had, but that was not the reason for the post, if you had read it...........

If 'alldigital' fixed it, then you're on the wrong forum!

[f_lez]

Ok I add 'alldigital' to my code and I compile and it works, but its not a supported command.......


Scary........


Ok save the hex, recompile without the 'alldigital' and compare the hex, no difference............

Damn these chips!

I'll just go sit in a corner for a while and rock back and forth.

f_lez,

To make it clear, "alldigital" is not a command of PBP's.

It is a command of another compiler.

Thus, one should avoid posting "things" about another compiler on this forum.

That is what Melanie kindly meant.

chill down sayser,

and read the posts carefully.

ps:

I'm sure if Melanie would need a parrot she'll buy one

cheers

i suggest our friend open the PIC datasheet in section 21(analog converter) and 22(analog comparator)

From there, you have to find how to disable AllAnalog stuff to make your i/o AllDigital.

Claxon1... you should read and write better the name of Sayzer
