 PlatformIO development platform for IoT modules manufactured by Tuya Inc.

 The main goal of this project is to provide a usable build environment for IoT developers. While also providing vendor SDKs as PlatformIO cores,
-the project focuses on developing working Arduino-compatible cores for supported platforms. The cores are inspired by Espressif's official core for ESP32,
-which should make it easier to port/run existing ESP apps on Tuya IoT (and 3-rd party) platforms.

-### Realtek Ameba
-
-The logic behind naming of Realtek chips and their series took me some time to figure out:
- RTL8xxxA - Ameba1/Ameba Series
- RTL8xxxB - AmebaZ Series
- RTL8xxxC - AmebaZ2/ZII Series
- RTL8xxxD - AmebaD Series
-
-As such, there are numerous CPUs with the same numbers but different series, which makes them require different code and SDKs.
- [RTL8195AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8195am)
- RTL8710AF (found in amb1_arduino)
- [RTL8711AM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8711am)
- [RTL8710BN](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710bn)
- RTL8710BX (found in Tuya product pages)
- RTL8710B? (found in amb1_sdk)
- RTL8711B? (found in amb1_sdk)
- [RTL8710CM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8710cm)
- RTL8722CSM (found in ambd_arduino)
- RTL8720DN (found in ambd_arduino)
- [RTL8721DM](https://www.realtek.com/en/products/communications-network-ics/item/rtl8721dm)
- RTL8722DM (found in ambd_arduino)
- and probably many more
-
-Different Ameba series are not compatible with each other. Apparently, there isn't an official public SDK for AmebaZ that can support C++ properly.

+ESP8266 Multicast DNS (port of CC3000 Multicast DNS library)
+Version 1.1
+Copyright (c) 2013 Tony DiCola (tony@tonydicola.com)
+ESP8266 port (c) 2015 Ivan Grokhotkov (ivan@esp8266.com)
+MDNS-SD Suport 2015 Hristo Gochkov (hristo@espressif.com)
+Extended MDNS-SD support 2016 Lars Englund (lars.englund@gmail.com)
+Rewritten for ESP32 by Hristo Gochkov (hristo@espressif.com)
+
+This is a simple implementation of multicast DNS query support for an Arduino
+running on ESP32 chip.
+
+Usage:
+- Include the ESP32 Multicast DNS library in the sketch.
+- Call the begin method in the sketch's setup and provide a domain name (without
+  the '.local' suffix, i.e. just provide 'foo' to resolve 'foo.local'), and the
+  Adafruit CC3000 class instance.  Optionally provide a time to live (in seconds)
+  for the DNS record--the default is 1 hour.
+- Call the update method in each iteration of the sketch's loop function.
