why this line have error in CCS ?
setup_wdt(WDT_ON);
setup_wdt(WDT_2304MS|WDT_DIV_16); //~2.3 s reset
Please send example Source code for PIC12f629 WDT and sleep mode. |

Have a look at the header for that PIC.
12F629.h
Are those 3 options available ?? |

Also look at the data sheet.
What is the longest time the watchdog is quoted to give?. 2304mSec....
Does the watchdog on this chip have an option to disable in software?. No.....
CCS can only give you options the chip actually has. |

| Yes that PIC has a sleep mode according to the datasheet, special features chapter. It's also noted in the device header that CCS supplies. |

| Code: |
#include <12F629.h>
#FUSES WDT //Watch Dog Timer
#FUSES INTRC_IO //Internal RC Osc, no CLKOUT
#FUSES NOBROWNOUT //No brownout reset
#use delay(int=4000000)
void main()
{
setup_wdt(WDT_2304MS); //program 2 sec (approx)
setup_comparator(NC_NC);
while (TRUE)
{
output_toggle(PIN_A0);
sleep();
delay_cycles(1); //nop instruction after sleep
}
}
|
This will toggle pin A0 just over every couple of seconds (but beware the WDT time is _very_ approximate - about 1.7 secs to about 2.6 secs), while the chip will sleep almost all the time. |
