## 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).

|
||||||
|
|
||||||
|
We are committed to making participation in this project a harassment-free experience for everyone, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.

# 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.

# 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 temperatue, bmp180_press_t pressure) {
|
||||||
|
my_event_t ev;
|
||||||
|
|
||||||
|
ev.event_type = MY_EVT_BMP180;
|
||||||
|
ev.bmp180_data.cmd = cmd;
|
||||||
|
ev.bmp180_data.temperatue = temperatue;
|
||||||
|
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, ®_addr, reg_data, 1);
|
||||||
|
|
||||||
|
````
|
||||||
|
|
||||||
|
The driver is released under the MIT license.
