# 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.
