* `FreeRTOS` contains FreeRTOS implementation, subdirectory structure is the standard FreeRTOS structure. `FreeRTOS/source/portable/esp8266/` contains the ESP8266 port.
|
||||
* `lwip` and `axtls` contain the lwIP TCP/IP library and the axTLS TLS library ('libssl' in the esp8266 SDKs), respectively. See [Third Party Libraries](https://github.com/SuperHouse/esp-open-rtos/wiki/Third-Party-Libraries) wiki page for details.

* `lwip` contains the lwIP TCP/IP library. See [Third Party Libraries](https://github.com/SuperHouse/esp-open-rtos/wiki/Third-Party-Libraries) wiki page for details.
|

* `libc` contains the newlib libc. [Libc details here](https://github.com/SuperHouse/esp-open-rtos/wiki/libc-configuration).

## Open Source Components

* [FreeRTOS](http://freertos.org) V7.5.2
|
||||
* [lwIP](http://lwip.wikia.com/wiki/LwIP_Wiki) v1.4.1, modified via the [esp-lwip project](https://github.com/kadamski/esp-lwip) by @kadamski.
|
||||
* [axTLS](http://axtls.sourceforge.net/) compiled from development version v1.5.3, plus modifications for low memory devices.
|
||||
* [newlib](https://github.com/projectgus/newlib-xtensa) v2.2.0, with patches for xtensa support and locking stubs for thread-safe operation on FreeRTOS.
