| C library to communicate with I2C bus directly. |
| |
| Notes: |
| [1] The goal of this module is to enable direct I/O operations on I2C bus |
| with minimal overhead. Although i2c-tools has been made available in |
| Chromium OS, it still carries much overhead (as revealed by strace). |
| |
| [2] The original source code was posted to Linux Kernel Documentation |
| (http://www.mjmwired.net/kernel/Documentation/i2c/dev-interface) and |
| has been modified and adopted here. According to this source, there are |
| two versions of i2c-dev.h, one distributed with the Linux kernel and the |
| other with i2c-tools. This module depends on the kernel version. |
| |
| [3] The included Makefile creates a C shared library object (.so file), which |
| can then be imported into Python via ctypes for developing new Autotest |
| test cases for I2C devices. |
