Alternative firmware for ESP8266 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation atProject mention: How to add LED brightness control to this code - Project Guidance | reddit.com/r/arduino | 2021-09-21
It's why most of us cheat and use a WS281x chip to provide one wire control with the FastLED or NeoPixel libraries. That said, I think the Tasmota project used to have code for brightness control on discrete RGB LEDs.

🚀 The fastest WebAssembly interpreter, and the most universal runtimeProject mention: Does it make sense to write an interpreter in a non-GC programming language (like Rust or C)? | reddit.com/r/ProgrammingLanguages | 2021-08-11
I wondered if some interpreter for non garbage collected languages existed. I found one for Web assembly https://github.com/wasm3/wasm3 (written in C) There are apparently several C interpreters too.

Native Apple HomeKit accessory implementation for the ESP8266 Arduino core.Project mention: ESP HomeKit Project | reddit.com/r/arduino | 2021-05-09
Hey, i tried to turn on an LED through the apple home app and it worked perfectly. I tried tweaking the code a bit and it stopped working so i went back to the original code ( that worked in the first place ) and it never worked the again even when i use it untouched straight from the examples i got from - https://github.com/Mixiaoxiao/Arduino-HomeKit-ESP8266 - So what may be the problem? I am making sure that i am setting the wifi SSID and password correctly. Can it be because the board i am using is cheap ( from ali express ). I am using an esp32.

A lightweight, secure, easy-to-use crypto library suitable for constrained environments.
MQTT Broker library for ESP8266 ArduinoProject mention: Should I even try? | reddit.com/r/esp8266 | 2021-08-27
You could use MQTT as a form of communication for all the devices, and make all your messages retained, so whenever some device updates the status, all subscribed devices will receive the new message, and because the messages are retained any new device will imediatly receive the retained messages, essencially syncing all current and future devices. Technically you will have an MQTT server, or better know as broker in this context, so a RPi would a good ideia, but an ESP8266 might be sufficient, I've beber tried it though A quick search on Google lead me to this link: "GitHub - martin-ger/uMQTTBroker: MQTT Broker library for ESP8266 Arduino" https://github.com/martin-ger/uMQTTBroker .
RunCPM is a multi-platform, portable, Z80 CP/M 2.2 emulator.Project mention: Ask HN: Are impressive new programs being written for CP/M? | news.ycombinator.com | 2021-05-01
There are no doubt some systems still running under emulation doing the same thing as they were 40 years ago. But the truth is CP/M is dead. Long live CP/M!
It's just hobbyists now. One hacker ported his game to a Kaypro under CP/M a couple years ago: http://www.chrisfenton.com/dd9-kaypro-edition/
Much of the focus is on porting CP/M to whatever new or old Z80 system someone has built or found. I can't think of anything particularly dazzling besides the above, in terms of recent new programs, but here are some pointers if you wanted to write something yourself!
RunCPM is a CP/M Z80 virtual machine under modern OSes for development etc. https://github.com/MockbaTheBorg/RunCPM
CP/Mish is an attempt to bring all the free software CP/M tools together. It is to CP/M as Linux is to UNIX, or FreeDOS is to MS-DOS. A mostly complete, improved, libre reimplementation: https://github.com/davidgiven/cpmish
Also from David Given (and not CP/M specific) is Cowgol. Alpha quality. But it's a self-hosted Pascal/Ada-like language with compiler. Runs on 8-bit systems, at least theoretically. It is written, of course, entirely in Cowgol: https://github.com/davidgiven/cowgol
Millfork is a language which targets CP/M systems, among others. It's a whole-program optimizing compiler for a language somewhat lower level than C, with properties that make it very nice to compile for 8-bit systems like no recursion, and no automatic promotion to 16-bit integers in type handling: https://github.com/KarolS/millfork
SDCC supports the platform with C surprisingly well. I wouldn't call it rock-solid but compared to the above toys it is an industrial quality compiler for the Z80. In fact, C seems to be the most common actual language for hobbyist and the little remaining serious Z80 development, probably ahead of assembly.
If it just reads and writes the terminal and can fit in 64 KB, then a port is probably straightforward.
Remote Serial monitor for ESP8266 & ESP32Project mention: ESP8266 webserver with serial output | reddit.com/r/arduino | 2021-09-19
This is an ESP32 / ESP8266 WiFi Connection Manager with fallback web configuration portal. Use this library for configuring ESP32 (including ESP32-S2 and ESP32-C3), ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel.

Yes, this is the normal way to do it. There are several excellent libraries around including this one for ESP32.
