Help again please with Sleep function

[Keith]

Many moons ago you helped with some code you wrote for me to send a PIC29F202 into sleep. The code you wrote was:

SysBYTETempA = On_signal
'Clear the port change reset flag
Set GPWUF off

  movlw B'01001111'   'This is assembler.  :-)
  option
  'Return to sleep
  wait 3 S
  sleep
  nop

The code has been recycled many times by simply changing the £On_signal " line.

the PIC16F18346 I'm using in this latest project doesn't want to know this and spits it out as if it were a nasty taste.
Having resolved all the project issues, i'm on the last hurdle and quite pleased with the outcome but I want the processor to go to sleep - any help would be really appreciated

Just enter the command sleep

[Keith]

So I don't use any of the code instructions as befpre with the 10F202 and 12F508 ?

Thats magic - Thank you.

[Anobium]

What event will wake the chip? That may help answer.

[Keith]

Yes, that is a problem. it goesn't go to sleep. It becomes Comatosed!.

I need it come back to life on pressing the encoder switch on PortB.6

The code is below - Thank you

[Anobium]

Try this following to wake.

// Both edges (most common for buttons/encoders)
IOCBP6 = 1
IOCBN6 = 1

' =============================================
' Enable Interrupts
' =============================================
On Interrupt PORTABChange Call Handle_IOC   ' Link IOC interrupt to subroutine


// code, lots of it.


' =============================================
' Interrupt Service Routine (ISR)
' =============================================
Handle_IOC:

    If IOCBF.6 = 1 Then             ' Check if RB6 caused the interrupt
        IOCBF.6 = 0                 ' Clear the flag for RB6

    End If

Return

[Keith]

Thank you once again. It works a treat.
I put the first part of the routine above my main program as:

' =============================================
' Enable Interrupts sor Sleep Function
' =============================================

// Both edges (most common for buttons/encoders)

IOCBP6 = 1 ;Required
IOCBN6 = 1 ;Required

On Interrupt PORTABChange Call Handle_IOC ' Link IOC interrupt to subroutine

Main: ;----- start main*******

and a Sub called Handle_IOC ....
Calling up that Sub routine when the Main program times out and is inactive

Sub Handle_IOC ' Link IOC interrupt to subroutine

Sleep

' =============================================
' Interrupt Service Routine (ISR)
' =============================================
Handle_IOC:

    If IOCBF.6 = 1 Then             ' Check if RB6 caused the interrupt
     IOCBF.6 = 0                 ' Clear the flag for RB6

    End If

End Sub

As I said it works really well downing the current to a couple of uA's

Thank you
