i hope one day i'll be able to do nice schematic like that. I really need to trash my P-Cad and use your software instead

Hello mister E

I am using PICBASIC COMPILER 1,45 and the following one I cosay does not work, I want to me to ignite the LED in pin2 by 1 minute and as soon as another minute is extinguished and continue the sequence but does not work to me, some suggestion.

I am using a PIC12F675.

Thanks


'code

Symbol Mi = B0
Symbol Se = B1

TOP:
Dir2 = 1 ' make Pins 2 and 1 outputs
Dir1 = 1

Pin2 = 0 ' turn off lamp - off or 1 minute
For Mi = 1 to 1 'minutes
For Se = 1 to 60 ' seconds
Pin1 = 1 ' test LED
Pause 500
Pin1 = 0
Pause 500
Next
Next

Pin2 = 1 ' turn lamp on - on for 1 minute

For Mi = 1 to 1 ' minutes
For Se = 1 to 60 ' seconds
Pin1 = 1
Pause 500
Pin1 = 0
Pause 500
Next

Hello leonardo,

I think I understand what you are trying to do... Try this...This is assuming your previous code compiles... I do not have PB, I only have PBP.

Try something like this:

'code

Symbol Mi = B0
Symbol Se = B1

TOP:
Dir2 = 1 ' make Pins 2 and 1 outputs
Dir1 = 1

Pin2 = 0 ' turn off lamp -  1 minute
Pin1 = 1' Turn on Lamp 
For Se = 1 to 60 ' seconds
Pause 1000
Next

Pin2 = 1 ' turn lamp on - on for 1 minute
Pin1=0 'turn Lamp off for 1 minute.

For Se = 1 to 60 ' seconds
Pause 1000
Next

Leonardo,

See your other post in the General forum.

You need to change their mode as part of your a setup

Try:

poke $19, $7 'to disable comparator mode for pins 0 & 1

See the manual regarding these pins as comparators.

When used as comparators, the 12f629/75 make a great op-amp. It is on or off, no slope, and the turn on can be "smart. I made an "on at dark" light switch that stays on only 4 hours.
