Python library for SIM900 (GSM/GPRS) modules. MIT licensed

Yahoo! I have published to the github.com my Python library for SIM900 GSM/GPRS modules - sim-module. It's MIT licensed and you can use it freely for commercial and non-commercial use.

You can find it here: https://github.com/JFF-Bohdan/sim-module

It can be used everywhere where you can find Python:

• PC (Windows, Linux, Mac);
• ARM computers with Linux: Raspberry Pi for example.

Now it supports HTTP POST and GET requests.

Enjoy!

Problem with I2C on Raspberry Pi after Raspbian update

Problem with I2C on Raspberry Pi after Raspbian update 

 Problem

My DS3231 does not work on Raspberry Pi after update for Linux 3.18.5+ :(

Solution

The latest firmware implements device tree support. That will have broken things like I2C, SPI, and 1-wire bus.
