Skip to content A couple weeks back we brought you news of KernelUNO, a command line shell and very simple operating system for the Arduino Uno. It’s a neat idea, so it’s hardly surprising to see someone port it to another microcontroller and add more features. Here’s [hery-torrado], with KernelESP for the ESP8266 , which takes the original idea and adds a web console, scheduled jobs, sensor rules, scripting, NTP, and a JSON API. The networking using the ESP’s built-in WiFi takes the original and makes it significantly more useful. It’s worth suggesting that the ability to call URLs with GET data to pass things to APIs would be useful on a networked processor too, but this is already so well featured it seems rude to ask for more. Yet again though, this project has given a new life to an old chip, and we think it has a way further to go. Perhaps a port to the ESP32 would allow it to reach its full potential, or maybe for a ridiculously cheap and powerful platform, the CH32 series of chips.…
