A customer recently contacted Yoctopuce support to ask why his DIY tachometer didn't work with a Yocto-PWM-Rx. We looked into it and, to our surprise, we discovered that generating a clean PWM signal with a magnet and a reed switch was not as easy as one could think.
Creating a software to query an SPI sensor contains a number of traps, linked to the specificities of this communication mode. This post provides some advice to avoid the most frequent pitfalls.
Three years ago, we gave you a small preview of what could be a Yoctopuce module used to drive stepper motors. In the mean time, a lot of time has past, but this module is still not for sale. We do intend to offer it in the future, but if in between you need to drive a stepper motor for a simple application, we may have a solution for you ...
Thanks to the new Yocto-I2C one can basically interface any I2C device, but one can also simply use it to test any I2C device. This week we decided to use this possibility to play with Amphenol's DLHR pressure sensors.
One of the complex and recurring questions that we get is the use of rechargeable batteries to power autonomous measuring systems. Using a backup battery for smart phone provides an easy solution, but adequate models for this kind of use are not that frequent. Today, we present two alternatives that you can use in specific cases.
