We already showed you in a previous post how to use a Yocto-Serial to decode Wiegand messages over USB, for instance to interface an RFID reader. And as we could have guessed, someone asked a bit later if the reverse was possible as well: can we send Wiegand messages using the same USB interface? The answer is yes, it is now possible as well. Let's see how to proceed...
This week, we are going to discuss isolated Yoctopuce modules. What is this famous isolation? How is it implemented? What's its use? What are the consequences?
YoctoHubs cannot connect directly to the IFTTT cloud service, but you can still use our modules with this platform thanks to the Webhooks. We are going to see how to publish the values measured by a Yocto-Meteo-V2 on different services thanks to IFTTT and Webhooks.
If you have already tried to build a control panel interfaced by USB with many ON/OFF buttons, you know that it's not as simple as it may seem. Not only the multiplication of buttons makes the wiring process quickly complex, but if you are limited to 5 or 8 inputs per module, the number of interface modules that you must use increases rapidly. A way to improve these two issues consists in multiplexing several buttons on a single analog interface, and this is what we are going to show you today.
We just realized that we never really talked about the animation system integrated into Yoctopuce displays. There is a short note about it in the documentation, required functions are documented, there is a example in every Yoctopuce programming library. But we never explained how it works. This week, after only 7 seven years, we make up for it.
