Angular Decoder Input IP

Block Info

Version: 1.0
First Release: FPGAWB 2018.1-0

The Angular Decoder IP module takes A, B and Z input from an angular encoder and will output X1, X2 ans X4 counter values. X1, X2 and X4 count the edges of the A and B input waveforms to estimate the current angle. This module can use the Z input to reset the counter to signify a 360 degree rotation. If the user knows the maximum number of edges then the Z signal can be omitted and the user can just configure the profile length.


Example 1

The A, B, and Z signals from the digital Encoder Output block is connected to the A, B and Z signals of the Decoder Input block.
