HSERVOWAIT
hservowait [pin1, ..., pinN]
Commands
In some situations it may be necessary to wait for the HSERVO command to fi nish updating the servo
position before program execution resumes. The HSERVOWAIT command is used to delay program
execution until HSERVO has fi nished moving the servos specifi ed.
Example
The example below will pause program execution until servos attached to PO through P4 are fi nished
being moved to new positions.
hservowait [p0,p1,p2,p3,p4]
HSERVOPOS
hservopos pin
To determine the current position a particular servo is set to, the HSERVOPOS command is used.
The value returned is the position the HSERVO system is currently driving the servo at. Typically,
there is no feedback from a servo for a true position.
Example
The example below sets a word sized variable and loads it with the last position used for a servo
attached to P0.
temp var word
temp = hservopos p0
HSERVOIDLE
hservoidle pin
To determine if a servo is still being moved to a new position by HSERVO, the HSERVOIDLE
command is used. It will return a value of 0 if the servo specifi ed is not idle. If the specifi ed servo has
reached its new position a value not equal to 0 (0xFFFFFFFF) will be returned.
Example
The example below will update a servo on PO. The program will loop and report until the servo is idle.
hservo [p0\0]
pause 1000
hservo [p0\1000\100]
main
if (NOT hservoidle p0) then
serout s_out,i9600,[“Servo P0 is not idle”,13]
endif
goto main
