Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Interrupt for hx711
There's an example using the ULP here: https://github.com/boarchuz/HULP/blob/c410904472113614aa31c36ed2924c432732ca18/examples/HX711/calibrate_and_wake/main/main.c

How to tell the ULP co-processor what to do?
I think you’re probably looking for this one: https://github.com/boarchuz/HULP
-
Ideas to make a esp32 wake up, send a EspNow msg, and sleep as fast as possible
Maybe https://github.com/boarchuz/HULP will be useful for the ULP? It supports IDF and Arduino, though admittedly there's not much effort on the Arduino side.

ESP32 ULP coprocessor programming in Arduino or Platformio with minimum fuss?
The /u/boarchuz HULP macro method would be great, but it doesn't work properly without the Arduino 2.0 IDE.

ESP32 and A barcode scanner
I can't vouch for it but there is a project which implements a USB host in software on an ESP32 here: https://github.com/sdima1357/esp32_usb_soft_host
-
which pins can i use with USB type B?
I doubt OP is up for wrangling that route though, I found this USB host project but it's a low-speed only proof of concept, not a fully fleshed out library.
-
Just a little tip to make your ESP32 kinda work like a regular USB device
To actually make an ESP32 do USB in software, see an example here.
-
What is currently the best solution to run the ESP32 in USB host mode?
I found this soft solution and I'm aware of a more complex hardware add-on.

Reading a Weather panel USB output (Easyweather)?
It's quite possible that the weather station is an HID device itself, in which case esp32_soft_usb_host might just work.
