 |
|
what am I as a noob doing wrong here?
This code prints out zero, as does a power-on reset.
| Code: |
sub main()
console.writeline ("Reset cause: " & cstr(Register.ResetFlags) )
OpenWatchDog(6) ' arg is 16.384 mSec x 2 to the nth power, n=parameter value
end sub

Yes there seems to be a problem here.
If you replace Register.ResetFlags by Register.MCUCSR, I think you achieve the same result. I get a 0x1 for power on, 0x11 for external reset and 0x1011 for the watchdog. |

A Firmware Update has been posted that resolves this problem.
It should be noted that at boot time, the reset flags in the MCUCSR register will be copied to Register.ResetFlags and then the reset flags are cleared from MCUCSR. This strategy is necessary since the existing reset flags are not cleared when the processor resets. |
