Hello,
how can I check if there's been a watchdog reset?

| There is a function called restart_cause() that gives you the reason for reset. As for the values it returns, quoting from the manual: A value indicating the cause of the last processor reset.The actual values are device dependent. See the device .h file for specific values for a specific device. Some example values are: WDT_FROM_SLEEP, WDT_TIMEOUT, MCLR_FROM_SLEEP and NORMAL_POWER_UP. |

Yes -- however, if you're using the debugger, it will always show that the restart cause is "normal power up." Not sure why... Just something to watch out for...

Probably because the debugger drives the MCLR line to the target PIC low. That would look like a "normal power up" reset to the PIC and would be reflected in the target PIC status bits. That's just a guess on my part, but it seems logical. |
