Pico PIO state machine implements a peripheral: Rotary Decoder - 1: example/products/raspberry-pi/b/blog/posts/pico-pio-state-machine-implements-a-peripheral-rotary-decoder---1-exampleThe Pico has a set of PIO co-processors. They are real-time controllers that can execute logic with deterministic timing. Ideal to run strict-timed sequences and state machines. And to implement extra peripherals (like a quadrature decoder h...en-USTelligent Community 12RE: Pico PIO state machine implements a peripheral: Rotary Decoder - 1: examplehttps://community.element14.com/products/raspberry-pi/b/blog/posts/pico-pio-state-machine-implements-a-peripheral-rotary-decoder---1-exampleSun, 13 Nov 2022 20:20:36 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e4424811-ca93-4040-b886-b9159595ac4aJan Cumps0<p>I just found out that the standard raspberry pico-examples also have a good <a href="https://github.com/raspberrypi/pico-examples/tree/master/pio/quadrature_encoder" rel="noopener noreferrer" target="_blank">PIO quadrature encoder example</a>.</p> <p>To make it work with the pico Eurocard, change this line of code:</p> <div> <pre><span>// &nbsp;const uint PIN_AB = 10;</span></pre> <pre>&nbsp; &nbsp; <span>const</span><span> </span><span>uint</span><span> </span><span>PIN_AB</span><span> = </span><span>6</span><span>;</span></pre> </div><img src="https://community.element14.com/aggbug?PostID=24735&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">RE: Pico PIO state machine implements a peripheral: Rotary Decoder - 1: examplehttps://community.element14.com/products/raspberry-pi/b/blog/posts/pico-pio-state-machine-implements-a-peripheral-rotary-decoder---1-exampleMon, 07 Nov 2022 17:47:24 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e4424811-ca93-4040-b886-b9159595ac4aJan Cumps0<p>I&#39;ve attached the VSCode project</p><img src="https://community.element14.com/aggbug?PostID=24735&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">
