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.

How to port ESP-IDF code to an Arduino library?
Here is my DMX library which supports both Arduino and ESP-IDF if you are looking for help. It also supports PlatformIO.

Code Review & Future Design Choices
ESP-IDF vs. Arduino: I'm currently using the Arduino wrapper because I've been doing Arduino for a big part of my microcontrolling life now. But I've heard that ESP-IDF is much better as it's the native solution. Is that true and what are the benefits? I'd like to decide that now, because once a bigger part of my codebase is built, I won't be able to change it again without spending many, many hours. So what is best for my purpose and what is the coding experience like? For example, what should one use instead of pinMode etc. Just maybe a basic overview of the key differences and a good resource to learn from. The libraries I'm going to use: https://github.com/sfranzyshen/ESP-Arduino-Lua and https://github.com/someweisguy/esp_dmx

DMX from Arduino?
I wrote a DMX library for ESP32 if you are interested in checking it out. It currently supports transmitting RDM and I am working on supporting receiving RDM as well. As far as I know, I am the only one working on RDM support at this scale. The library runs on Arduino, but you must use an ESP32-family microcontroller.

Control a Bluetooth bulb with DMX
I don't normally plug my DMX software on this sub because I, personally, would be hesitant of trusting DIY software for show-critical gear, but: if you're going the non-RPI route, your best bet may be ESP32. I wrote a software library for DMX on the ESP32 which can be found here, if you're interested. I am currently working on adding RDM!

My ESP32 DMX Library Now Supports RDM!
I've been working on an ESP32 library for the past few years called esp_dmx. I've just published a pre-release of v3.0 which finally supports RDM.

DMX512 code writer
It's not clear to me if you're looking for a specific library, but if you use ESP32 (either Arduino, or ESP-IDF) I wrote a library that can read or send DMX.
-
Microcontroller Receive DMX
I wrote a C library (sorry, not Python) for ESP32 called esp_dmx that also has some tools for analyzing DMX packets just like those fancy, expensive DMX sniffer tools. I'm currently working on support for RDM!

Any good/worthwhile Camera sensor modules for arduino/pico for still photography?
You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.
- I am trying to write to an SD card, it "works" but I can only find the file on PC if I use data recovery software?

ESP32 memory corruption
Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

ESP32 S2 Help

The Nano ESP32
That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.
The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.
Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32
Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

Arduino Uno R4 WiFi
They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]
It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]
