ISR

(

TIMER3_OVF_vect

)

Increment sleep counter with each timer overflow.

Definition at line 56 of file sleep.c.

void sleep_check

(

)

Checks running conditions for sleep. If satisfied, enables sleep countdown and executes.

NOTE: Sleep procedures can be blocking, since Grbl isn't receiving any commands, nor moving.

NOTE: With overrides or in laser mode, modal spindle and coolant state are not guaranteed. Need

Definition at line 88 of file sleep.c.

void sleep_init

(

)

Initialization routine for sleep timer.

Initialize sleep timer.

NOTE: By using an overflow interrupt, the timer is automatically reloaded upon overflow.

< Normal operation. Overflow.

< Stop timer

< Enable timer with 1/64 prescaler. ~66.8sec max with uint8 and 0.262sec/tick
