I checked estop_latch.comp and find:
FUNCTION(_) {
/* check inputs */
if ( ok_in && !fault_in) {
/* no fault conditions, check for reset edge */
if ( reset && !data.old_reset ) {
/* got a rising edge, indicate "OK" on outputs */
ok_out = 1;
fault_out = 0;
}
/* toggle watchdog */
//OLD LINE
watchdog = !watchdog; 'AS I UNDERSTAND THIS TOGLE IF (
ok_in && !fault_in)
//NEW LINE
if ( ok_out ) {watchdog = !watchdog;} 'I CHANGED PREVIOUS LINE INTO
THIS NOW WORKS
} else {
/* fault condition exists, trip */
ok_out = 0;
fault_out = 1;
}
/* store state of reset input for next pass (for edge detect) */
data.old_reset = reset;
}
I'm not familiar enought with git to make update/patch. So please some
of the "bosses" to do that.
Thanks
Slavko.
