 ===== Programming ===== ===== Programming =====
  
 +To use LabVIEW to program Hitechnic NXT Angle Sensor, you must first installed LabVIEW module for LEGO MINDSTORMS. Follow [[labview_nxt_tutorial#installation_guide| this link]] for direction on how to install LabVIEW or the MINDSTORMS module.
 +
 +To access block diagram nodes for Angle Sensor, go to ''Function Palette'' -> ''MINDSTORMS Robotics'' -> ''I/O'' -> ''Additional Sensors'' -> ''Hitechnic Sensors''.
 +{{ :yuhang:hitechnic_angle_encoder:hitechnic_block_diagram.png?500 |}} 
 +
 +To receive inputs from Angle Sensor, use the ''HT Read'' node. The ''HT Read'' node is a polymorphic VI and Angle Sensor is one instance of the node. Click on the text box below the node to browse different implementations. 
 +{{ :yuhang:hitechnic_angle_encoder:ht_read.png | HT Read}}
 +
 +HT Read have four different implementations:
 +  *''Angle'': returns the rotation position of a rotating axle from 0 – 359 degrees with 1 degree accuracy
 +  *''Total Angle'': returns the accumulated number of degrees an axle has rotated
 +  *''RPM'': returns the speed of the axle rotation in RPM (revolutions per minute)
 +  *''All Info'': returns all three readings in a cluster structure
 +
 +To reset the angle and accumulated angle, use the HT config node, which can be assessed under ''Hitechnic Sensors''.
 +\\ 
 +''HT Wait For'', which is also under ''Hitechnic Sensors'' group, can also be used to interact with Angle Sensor.
 +  *''Within 1 Degree'': wait until Angle Sensor angle reading is within 1 degree of the targeted value
 +  *''Within 5 Degree'': wait until Angle Sensor angle reading is within 5 degree of the targeted value
 +  *''Change'': wait until Angle Sensor accumulated angle is more than the targeted value
 +
