Google Calendar on your Yocto-Display-ePaper-C

By seb, in DIY, october 11,2026.

Twelve years ago, we built a DIY project that displayed upcoming events from a Google Calendar on a Yocto-MaxiDisplay that was built into a kitchen cabinet. This week, we're going to update this setup so that it uses our new Yocto-Display-ePaper-C module and shows the events on an ePaper display. We'll also take this opportunity to simplify the code and get rid of the OAuth2 authentication system.

A Yoctopuce time clock

By Tiago, in DIY, october 02,2026.

A while back, the Commission de l'inspection paritaire des entreprises (Joint Labor Inspection Commission) for the Canton of Geneva issued us a formal notice requiring us to implement a system for tracking work hours for all staff. Until now, Yoctopuce had operated on a trust-based system, and that had never caused the slightest problem. But hey, the law is the law, so we had no choice but to comply :( So, since we had to track work hours anyway, we figured we might as well do it the Yoctopuce way :)

Uploading firmware with XMODEM/YMODEM

By mvuilleu, in Programming, september 25,2026.

XMODEM and YMODEM are protocols that enable reliable file transfers over a serial connection (UART). They were designed 50 years ago to improve the reliability of data transfers over analog telephone lines, and one might have expected them to have disappeared completely by now. However, there are still a few specific cases where they are widely used, which is why we have just added native support for these protocols in our serial communication modules.

Yocto-FontEditor: A new font editor

By martinm, in New stuff, september 18,2026.

Quite early on in the development of the Yocto-Display-ePaper-C, we realized that the four fonts 8x8, small, medium, and large, which are included in the OLED display firmware, might not be sufficient due to the high resolution of the ePaper displays compatible with this new module. Rather than adding more arbitrarily chosen fonts and taking up space in the module's firmware, we decided to rewrite a new font editor from scratch to make it more practical and easier to use than the original editor, which no one seems to know exists....

Simplifying the process of connecting to VirtualHub for web

By seb september 15,2026.

While running some tests with VirtualHub (for web), we realized that nowhere in the interface did we specify which settings the YoctoHubs should use to connect. So we decided to add a new window to make it easier to add and configure YoctoHubs.
