‘Voodoo Reloaded’: the Enigma of Hardware vs Software Bugs | #ManufacturingMonday
Sometimes your bug is hardware. Sometimes your bug is software. But wait this software works on that hardware, and this and that hardware are the same, so why does that hardware have a bug? Oh man, I know the feeling. Which is actually why I thought this article was going to go in another direction – but it wound up concluding with something even I wasn’t foreshadowing or have experience with. And that makes it a good read – because debugging is all about variables and if you don’t have control over all of them, you will get different results!
Bugs in software are bad, bugs in hardware are even worse, but inconsistent results are what makes it a total nightmare.
Not my first post on crazy voodoo wasting precious time, I previously approached a similar issue here, so you can call this article “voodoo reloaded” without being far from the truth. Because sometimes those devices we spend so many hours to build – using the best of our logic and know how, seem to defy all that is normal and there remains very little we can do to fix the issues.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
