| #define ENCODER_MAXENCODERS 4 |
Gets the number of digital inputs supported by this board.
- Parameters:
-
phid An attached phidget encoder handle count The input count. Gets the state of a digital input. phid An attached phidget encoder handle index The input index. inputState The input state. Possible values are PTRUE and PFALSE. Sets an input change handler. This is called when a digital input changes. phid An attached phidget encoder handle fptr Callback function pointer. userPtr A pointer for use by the user - this value is passed back into the callback function. Gets the number of encoder inputs supported by this board. phid An attached phidget encoder handle count The encoder input count. Gets the current position of an encoder. phid An attached phidget encoder handle index The encoder input index. position The current position Sets the current position of an encoder. phid An attached phidget encoder handle index The encoder input index. position The new position Sets an encoder position change handler. This is called when an encoder position changes. phid An attached phidget encoder handle fptr Callback function pointer. Note that positionChange is a relative not absolute change and time is the time in ms since the last position change event. userPtr A pointer for use by the user - this value is passed back into the callback function. Sets an encoder index handler. This is called when there is a pulse on the index pin. phid An attached phidget encoder handle fptr Callback function pointer. This returns the encoder position at which the index pulse occured. userPtr A pointer for use by the user - this value is passed back into the callback function. Gets the position of the last index pulse, as referenced to CPhidgetEncoder_getPosition. This will return EPHIDGET_UNKNOWN if there hasn't been an index event, or if the encoder doesn't support index. phid An attached phidget encoder handle index The encoder index. position The index position. Gets the enabled state of an encoder. This is whether the encoder is powered or not. phid An attached phidget encoder handle index The encoder index. enabledState The enabled state. Possible values are PTRUE and PFALSE. Sets the enabled state of an encoder. This is whether the encoder is powered or not. phid An attached phidget encoder handle index The encoder index. enabledState The enabled state. Possible values are PTRUE and PFALSE.
