.. |I2C| replace:: I\ :sup:`2`\ C I2C Library =========== :Version: 6.2.0 :Vendor: XMOS Summary ------- A software defined, industry-standard, |I2C| library that allows you to control an |I2C| bus via xCORE ports. |I2C| is a two-wire hardware serial interface, first developed by Philips. The components in the libary are controlled via C using the XMOS multicore extensions (xC) and can either act as |I2C| master or slave. The libary is compatible with multiple slave devices existing on the same bus. The |I2C| master component can be used by multiple tasks within the xCORE device (each addressing the same or different slave devices). The library can also be used to implement multiple |I2C| physical interfaces on a single xCORE device simultaneously. Features ........ * |I2C| master and |I2C| slave modes. * Supports speed up to 400 Kb/s (|I2C| Fast-mode). * Clock stretching support. * Synchronous and asynchronous APIs for efficient usage of processing cores. Software version and dependencies ................................. The CHANGELOG contains information about the current and previous versions.
