aErr aServo_SetConfig(

aStemLib stemRef, const unsigned char module, const unsigned char nServoIndex, const unsigned char nConfigValue);

Parameters:

stemRef	-	An opaque library reference representing the aStem library which manages the communication with the BrainStem modules.
module	-	The IIC address of the module that will receive new configuration data for one of its servo pins.  This need not be the router.
nServoIndex	-	The index of the servo.
nConfigValue	-	The new configuration value.

Return Value:

This routine returns aErrNone when there are no errors.

Description:

This routine manages the BrainStem packets needed to set the configuration byte of a servo output.  The following defined bit masks may be used to configure servo outputs.

aSERVO_ENA	128	Set to enable the PWM output at a servo pin.   Clear to disable the PWM output at a servo pin.
aSERVO_INV	64	Set to use inverted positions for a servo.   Clear to use normal positions for a servo.
aSERVO_DSTA	32	Set to make the servo output remain high when the PWM is disabled.   Clear to make the servo output remain low when the PWM is disabled.

Add or logical-OR a value from 1 to 15 to the configuration bits to perform a speed-controlled servo motion.  The value 1 is the slowest speed and 15 is the fastest.  A speed of 0 will disable the speed function and make the servo move from one position to another as fast as it can go.
