Creating pulses at output port of PIC

[VRL_15]

--------------------------------------------------------------------------------

I am using PIC 16f887

I have a timer of 50 ms

Using that timer I want to create a pulse at the output port

The pulse should be 100 ms on then 100 ms off and then 500 ms off.

If anyone has an idea please let me know

Thank you

How about,

loop	bsf	PORTA,0
	call	del50
	call	del50
	bcf	PORTA,0
	call	del50
	call	del50
	goto	loop

I'll let you figure out how to set the pin to output.

Oh, yes, didn't understand the 500 off bit. Sounds like 600mS off to me.

what is del50?

 

[VRL_15]

yes it is 100 ms on and 600 ms off

Also I want to create that pulse using only the timer of 50 ms

del50 is your 50mS delay. I didn't bother explaining it as I thought it was kinda obvious.
