-Each output needs a statemachine running servo_trigger and one running servo_prog.
-Due to the IRQ assignments, the statemachines need to be in ordered to have the servo_trigger program first, e.g.:
-
-```
-trig = Servo_Trigger(0)                 # Statemachine 0
-s = Servo(1, 16) # phys IO on pin 16    # Statemachine 1, since the trigger is on SM0
-
-trig2 = Servo_Trigger(2)                # Statemachine 2
-s2 = Servo(3, 25) # Builtin LED         # Statemachine 3, since the trigger is on SM2
-```
+There needs to be one ServoTrigger Statemachine running.
+This Statemachine can trigger up to 3 other Servo Statemachines on the same pio instance.
