• ESP ZeroCode web application creates custom Matter-certifiable firmware for ESP32 targets

  Low-code/no-code platforms keep on coming and Espressif Systems ESP ZeroCode adds to the list. It is a web application designed to prepare Matter-certifiable firmware for ESP32 devices as per the user’s requirements. The website is supposed to streamline the product development where the firmware is developed for you (no need for those costly software/firmware engineers!) and future OTA updates are also guaranteed for a period of three years. It’s a bit similar to the Tuya platform, but for ESP32 devkits, modules, and/or rebranded products with Matter-certified firmware. So I went to the website to give it a try in Firefox in Ubuntu. After registration and login, we are given three options: Your products, Create a new product, and Rebrand a Certified Product I went with the second option and named by new product “CNX Software Gizmo”.

But having scheduler data inline with everything else you capture is too useful to pass up.

  Also been working with Juippis on masking firefox-bin and rust-bin in
  glibc llvm profile, Juippis has for now reverted the commit masking
  those bin packages, but likely a proper fix will be committed soon.

  Just warping things up for final review. I’m also in 1:1 contact with
  Sam in case there is some major work needed on a particular section of
  my project or a package.
