## Code Structure
* `examples` contains a range of example projects (one per subdirectory). Check them out!
* `include` contains header files from Espressif RTOS SDK, relating to the binary libraries & Xtensa core.
* `core` contains source & headers for low-level ESP8266 functions & peripherals. `core/include/esp` contains useful headers for peripheral access, etc. Minimal to no FreeRTOS dependencies.
* `extras` is a directory that contains optional components that can be added to your project. Most 'extras' components will have a corresponding example in the `examples` directory. Extras include:
- i2c - software i2c driver ([upstream project](https://github.com/kanflo/esp-open-rtos-driver-i2c))
- rboot-ota - OTA support (over-the-air updates) including a TFTP server for receiving updates ([for rboot by @raburton](http://richard.burtons.org/2015/05/18/rboot-a-new-boot-loader-for-esp8266/))
- bmp180 driver for digital pressure sensor ([upstream project](https://github.com/Angus71/esp-open-rtos-driver-bmp180))
* `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.
* `libc` contains the newlib libc. [Libc details here](https://github.com/SuperHouse/esp-open-rtos/wiki/libc-configuration).
