Another real world example: I&#39;m checking if the Xess Rotary Encoder library works with the encoder I use in a GaN half-bridge design.TL;DR: yes it worksXess has a plug-in board with aen-USTelligent Community 12https://community.element14.com/technologies/fpga-group/b/blog/posts/xula2-fpga---rotary-encoder-and-vhdlThu, 02 Feb 2017 22:29:15 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:c440dc87-f9da-44b0-8550-34a8717ccb56Jan Cumps1<p>This was supposed to be my first new attempt to create a VHDL module:&nbsp; a PWM signal with deadband.</p><p>I have a few things right <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c440dc87-f9da-44b0-8550-34a8717ccb56/contentimage_5F00_1.png:16:16]</span>&nbsp; </p><p>The frequency, the pin assignments, and the fact that the 2 signals are &quot;almost&quot; complementary.</p><p>&nbsp;</p><p>&nbsp;</p><p><span>[View:/resized-image/__size/796x456/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-c440dc87-f9da-44b0-8550-34a8717ccb56/contentimage_5F00_184839.png:796:456]</span></p><p>&nbsp;</p><p>Aaah, VHDL isn&#39;t too easy if you don&#39;t have the natural hang of it.
