Sleep & nap

[mackrackit]

there can be many things that can go wrong

That is when the fun starts

Can you post your whole code?
The actual problem might be someplace else.

Here, the fun has alredy started

DEFINE LOADER_USED 1
DEFINE RESET_ORG 1000h      ' For Microchip USB Bootloader
DEFINE INTERRUPT_ORG 1008h  ' For Microchip USB Bootloader
define WDT_ON
define WDTPS 128 

DEFINE LCD_DREG       PORTD	' Set LCD Data port
DEFINE LCD_DBIT       4		' Set starting Data bit (0 or 4 if 4-bit bus)
DEFINE LCD_RSREG      PORTC	' Set LCD Register Select port
DEFINE LCD_RSBIT      2		' Set LCD Register Select bit
DEFINE LCD_EREG       PORTC	' Set LCD Enable port
DEFINE LCD_EBIT       1		' Set LCD Enable bit
DEFINE LCD_BITS       4		' Set LCD bus size (4 or 8 bits)
DEFINE LCD_LINES      4		' Set number of lines on LCD
DEFINE LCD_COMMANDUS  2000	' Set command delay time in us, 2000 us = 2ms
DEFINE LCD_DATAUS     50	' Set data delay time in us, 50 us = 0,05ms

powerOut     var PORTE.0
onOffPressed var PORTD.2
b var byte
clear

TRISE = %00001000   
TRISC = %10110000   
TRISD = %00001100
powerOut = 1
   
pause 1
lcdout $FE, 1
pause 1

pstart:
  powerout = not onoffpressed
  lcdout $FE,2, "b=", dec b
  pause 100
  b = b + 1
  'nap 5
goto pstart

So, I can see b living with nap or sleep commented, but it hangs when not commented.

Hi,

From " The Manual" $ 5.46

The 16-bit
core devices, including the 17Cxxx and 18Xxxxx parts use a postscaler
set at programming time to configure the Watchdog timeout period.

The compiler will disregard the Period set in the NAP instruction for the 16-
bit core devices.

TRUE!

But SLEEP should work, shouldn't it?
The problem is somewhere else, but where?

Hi,

You want a ~1 sec PAUSE ...

use PAUSE 1000 !!!

a PAUSE can be "interrupted" so, there are no problem to use it ...

If you're using the Microchip USB loader, it may have WDT disabled in config.

Try inserting WDTCON.0=1 before any NAP or SLEEP commands to enable WDT.

One would have think that would work, but it did not
What might be wrong?

WDTCON.0=1
sleep 1
lcdout $FE, $C0, "ok"

Can't still se the "ok"
