/products/raspberry-pi/b/blog/posts/emulate-raspberry-pico-pio-programsThe 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.I&#39;m trying a PIO emulator&amp;nb...en-USTelligent Community 12https://community.element14.com/products/raspberry-pi/b/blog/posts/emulate-raspberry-pico-pio-programsSat, 12 Apr 2025 19:25:47 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e8c8ae92-9d97-43ea-b8f5-bbffdcdbb45eDAB0<p>Nice update Jan.</p> <p>Back in my day we always had issues debugging hardware and software integration.</p> <p>Things are so much better today.</p><img src="https://community.element14.com/aggbug?PostID=28827&AppID=86&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/b/blog/posts/emulate-raspberry-pico-pio-programsSat, 12 Apr 2025 09:50:13 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e8c8ae92-9d97-43ea-b8f5-bbffdcdbb45eJan Cumps0<p>The emulator needs the hex version of your PIO design. You can get that&nbsp;after building your project.
