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 i2c (BMP280) not working with ESP-IDF but OK with Arduino IDE
My next step is to try https://github.com/duff2013/ulptool to get the ULP working with Arduino IDE but it would be good to see why the ESP-IDF setup doesn't work for me and try to get it working as i wrote the code for it.

ESP32 ULP coprocessor programming in Arduino or Platformio with minimum fuss?
I've tried the ULPTool from Duff2013 and it screwed up my Arduino IDE; I had to remove the tool.
What are some alternatives?

esp-idf - Espressif IoT Development Framework. Official development framework for Espressif SoCs.
ESP32-Z80-Emulator - Z80 Emulator for ESP32 including Basic and CP/M 2.2
esp32_usb_soft_host - ESP32 software USB host through general IO pins. We can connect up to 4 USB-LS HID (keyboard mouse joystick) devices simultaneously.
PlatformIO - Your Gateway to Embedded Software Development Excellence :alien:
arduino-esp32 - Arduino core for the ESP32
Farm-Data-Relay-System - A system that uses ESP-NOW, LoRa, and other protocols to transport sensor data in remote areas without relying on WiFi.
