We talked about it for years, here it is at long last! The YoctoHub-GSM enables you to drive Yoctopuce modules in the middle of nowhere... as long as "nowhere" is not too far away from a GSM tower. But let's not spoil our fun and let's have a closer look...
A few months ago, the Raspberry Pi foundation announced a new Raspberry model: the Pi Zero. This new model evolved from model A, but is smaller and most importantly cheaper. This week, we received this new Raspberry Pi Zero. To test it, we decided to build an HDMI multimeter by connecting our USB sensors to the Raspberry Pi Zero.
The Yoctopuce API was designed to easily drive any Yoctopuce module with a minimum of code. It's therefore very easy to make an inventory of all the modules directly connected by USB to a machine. However, up till now, it was rather difficult, not to say impossible, to rebuild the exact tree structure of a system based on Yoctopuce modules, in particular for modules connected via the network. The latest version of the API now allows you to do this thanks to three new functions.
From time to time, people ask us if our roadmap would not include a digital USB potentiometer. The answer is no, because such product would probably be too limited to be useful. However, we can tell you how to build your own digital variable resistance, using just a few relays and resistors.
