OK, this is super weird. Color me puzzled.
I put together this #embedded #rustlang code on ESP32C3/C6 (tested on both) with Embassy, using a Sensirion SEN54 sensor to send data to my REST API. Here's the weird part: the code works, it sends data, but.. the data is wrong. Wrong as in "6553.5" values

It may not look like much but: the OLED is displaying data received in from my web app's REST API. The board is @seeedstudio.com Xiao ESP32C6, running #embedded #rustlang with Embassy. The carrier board is from Tindie.

As much as I bitch about this phone, including the camera being super slow sometimes or saying "processing...", sometimes it does a good job.

TFW you forget to add the division by 1_000_000_000 that was in the original function, push the data to Prometheus and all of a sudden your Grafana chart shows "10 ZB" in an S3 bucket :D Exa-ggerated-scale.

Espressif hired a bunch of Rust devs years ago and they have been quietly doing great work supporting Rust on their chips ever since. Still haven’t seen any other chip companies get close.

Hmmm, is there something special about I2C on the ESP32C6? I tried to port this code to the @seeedstudio.com Xiao ESP32C6, used the GPIO numbers provided in the wiki, but... the I2C device won't start. Tried with other devices tested on C3, same thing. But SPI works perfectly fine 🤔

Tinkering with #embedded #rustlang embassy framework and #esp32 is fun 🙃 And the @seeedstudio.com Xiao ESP32C3 with the Xiao expansion board are a perfect platform. Got a DFRobot ENS160 sensor breakout board and a single WS2812 connected, works pretty well. No photo ATM.

I somehow missed "Voodoo" back then, although I do remember seeing the cover in a music magazine, maybe read the review and thought that it wasn't quite my thing. Fast forward 20+ years to when I listened to "Dilla Time" audiobook during a long car trip and I thought, oh right, gotta check it out...

While Atsu can freely go around petting foxes in Ghost of Yotei, doing so in modern-day Hokkaido could be extremely dangerous.

I am literally old enough to have lived in a country where martial law was declared, to (choose your version) a) stop the Soviet invasion / b) keep the ruling "communist" party in power, AND:a Republican US president at the time made a big deal about that, seemingly. So there's that.
