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.

Neatest way of generating sub-Hz pwm signals with the ESP32
Do I write another softPWM-thingy but perhaps based on the interruptTimer Library? Is there a way to (easily) get lower PWM frequency?

ESP32 and peripherals (RMT, I2S)
Hello, I am trying to use FastLED with an interrupt-driven servo library, but the servo seems to jitter whenever the LED is showing any color except black (i.e. fully off). This leads me to believe that it's being bit-banged, and I'm not even sure how to check if FastLED is using any hardware peripherals like RMT or I2S. The jitter still happens when using #define FASTLED_RMT_MAX_CHANNELS 1, and I always get this warning during compilation, which might be relevant:
What are some alternatives?

ESPAsync_WiFiManager - This is an ESP32 (including ESP32-S2 and ESP32-C3) / ESP8266 WiFi Connection Manager, using ESPAsyncWebServer, with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- . Using AsyncDNSServer instead of DNSServer now.

ESP32_C3_TimerInterrupt - This library enables you to use Interrupt from Hardware Timers on an ESP32-C3-based board. These ESP32-C3 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.
