## 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:
- mbedtls - [mbedTLS](https://tls.mbed.org/) is a TLS/SSL library providing up to date secure connectivity and encryption support.
- 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` 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).

# I2C / BMP180 Example
This example references two addtional drivers [i2c](https://github.com/kanflo/esp-open-rtos-driver-i2c) and [bmp180](https://github.com/Angus71/esp-open-rtos-driver-bmp180), which are provided in the `../../extras` folder.
If you plan to use one or both of this drivers in your own projects, please check the main development pages for updated versions or reported issues.
To run this example connect the BMP085/BMP180 SCL to GPIO0 and SDA to GPIO2.

/* Special mbedTLS config file for http_get_mbedtls example,
overrides supported cipher suite list.
Overriding the set of cipher suites saves small amounts of ROM and
RAM, and is a good practice in general if you know what server(s)
you want to connect to.
However it's extra important here because the howsmyssl API sends
back the list of ciphers we send it as a JSON list in the, and we
only have a 4096kB receive buffer. If the server supported maximum
fragment length option then we wouldn't have this problem either,
but we do so this is a good workaround.
The ciphers chosen below are common ECDHE ciphers, the same ones
Firefox uses when connecting to a TLSv1.2 server.

# Driver for BMP085/BMP180 digital pressure sensor
This driver is written for usage with the ESP8266 and FreeRTOS ([esp-open-rtos](https://github.com/SuperHouse/esp-open-rtos) and [esp-open-rtos-driver-i2c](https://github.com/kanflo/esp-open-rtos-driver-i2c)).
### Usage
Before using the BMP180 module, the function `bmp180_init(SCL_PIN, SDA_PIN)` needs to be called to setup the I2C interface and do validation if the BMP180/BMP085 is accessible.
If the setup is sucessfully and a measurement is triggered, the result of the measurement is provided to the user as an event send via the `qQueue` provided with `bmp180_trigger_*measurement(pQueue);`
#### Example
```
#define SCL_PIN GPIO_ID_PIN(0)
#define SDA_PIN GPIO_ID_PIN(2)
...
if (!bmp180_init(SCL_PIN, SDA_PIN)) {
// An error occured, while dong the init (E.g device not found etc.)
}
// Trigger a measurement
bmp180_trigger_measurement(pQueue);
```
#### Change queue event
Per default the event send to the user via the provided queue is of the type `bmp180_result_t`. As this might not always be desired, a way is provided so that the user can provide a function, which creates and sends the event via the provided queue.
As all data aqquired from the BMP180/BMP085 is provided to the `bmp180_informUser` function, it is also possible to calculate new informations (E.g altitude etc.)
##### Example
```
// Own BMP180 User Inform Implementation
bool my_informUser(const xQueueHandle* resultQueue, uint8_t cmd, bmp180_temp_t temperature, bmp180_press_t pressure) {
my_event_t ev;
ev.event_type = MY_EVT_BMP180;
ev.bmp180_data.cmd = cmd;
ev.bmp180_data.temperature = temperature;
ev.bmp180_data.pressure = pressure;
return (xQueueSend(*resultQueue, &ev, 0) == pdTRUE);
}
...
// Use our user inform implementation
// needs to be set before first measurement is triggered
bmp180_informUser = my_informUser;
```

# Yet another I2C driver for the ESP8266
This time a driver for the excellent esp-open-rtos. This is a bit banging I2C driver based on the Wikipedia pesudo C code [1].
### Adding to your project
Add the driver to your project as a submodule rather than cloning it:
````
% git submodule add https://github.com/kanflo/esp-open-rtos-driver-i2c.git i2c
````
The esp-open-rtos makefile-fu will make sure the driver is built.
### Usage
````
#include <i2c.h>
#define SCL_PIN (0)
#define SDA_PIN (2)
uint8_t slave_addr = 0x20;
uint8_t reg_addr = 0x1f;
uint8_t reg_data;
uint8_t data[] = {reg_addr, 0xc8};
i2c_init(SCL_PIN, SDA_PIN);
// Write data to slave
bool success = i2c_slave_write(slave_addr, data, sizeof(data));
// Issue write to slave, sending reg_addr, followed by reading 1 byte
success = i2c_slave_read(slave_addr, &reg_addr, reg_data, 1);
````
The driver is released under the MIT license.
