aErr aDigital_WriteInt(

aStemLib stemRef, const unsigned char module, const unsigned char nDigitalIndex, int nDigitalValue);

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 a new output state for one of its digital IO pins.  This need not be the router.
nDigitalIndex	-	The index of the digital IO pin.
nDigitalValue	-	Integer with the new output value.

Return Value:

This routine returns aErrNone when there are no errors.

Description:

This routine manages the BrainStem packets needed to set the output state of a digital IO pin.  The new output state can be 0 or non-zero.  A 0 turns the output off.  A non-zero value turns it on.  The digital IO pin must be configured as an output prior to writing the new state.
