Inter-Integrated Circuit (I2C) Module

Overview

The Inter-Integrated Circuit (I2C) module is a serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, Analog-to-Digital (A/D) converters, Temperature and Humidity sensors, and so on.

Features

• The I2C interface supports the following operating modes
  • Host mode
  • Client mode
• The driver implementation is of non-blocking type and can be configured to operate in following modes
  • Polling
  • Interrupt

[7.0.0] - 2025-03-20

New Features and Improvements

• M8PD-14400 :- Updated I2C Peripheral Library v2 driver to generate the portable interfaces only when it is added via abstract driver

[6.2.0] - 2025-02-21

New Features and Improvements

• M8PD-7831 :- Enabled Register Editor view for the PLIB modules in MCC Melody
• M8PD-5940 :- Updated firmware to remove unnecessary static APIs
• M8PD-5530 :- Updated the API documentation for I2C Peripheral Library V2

[6.1.4] - 2024-12-19

Bug Fixes

• M8PD-12362 :- Corrected I2CXPIR register clearing to only clear stop interrupt bit on stop interrupt reception
• M8PD-11437 :- Fixed the I2C client to clear the ACKDT bit in I2CxCON1 after receiving a NACK from the host, which previously resulted in disabled clock stretching for subsequent requests
• M8PD-10837 :- Revised the error handler to include missing checks on error flags, which previously led to incorrect error event generation
• M8PD-5167 :- Removed the device specific warning and link to the Errata DS80000870F
