In the documentation for estop latch from
http://linuxcnc.org/docs/2.4/html/man/man9/estop_latch.9.html
is stated:
While ok-out is true, watchdog toggles, and can be used for chargepumps or
similar needs.
And I want just that!
But in reality the watchdog togles if ok_in is true and fault_in is false.
They not observe if latch is reseted.
So I change source estop_latch.comp to match the documentation. Ie the
watchdog output togle only if ok_out is true.
the change is on only one line!
Instead
watchdog = !watchdog;
i write
if ( ok_out ) {watchdog = !watchdog;}
And thing work's as is stated in documentation.
and gere is git output. And I don't know where how to post it.
I don't want to make some direect upload (probably I can't too) but some of
developers check if I make something wrong before updating.
