Enhanced I2C and SMbus Master Interface Reference Design with PRU-ICSS

TIDEP0065

Design files

Overview

This is a reference design for industrial communication on Sitara™ processors with Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS). PRU-ICSS allows custom firmware applications in the field of real-time applications. The I2C peripheral on many application processors does not support SMbus commands like block-read and block-write transfers. This reference design implements those SMbus commands with standard I2C commands into the PRU-ICSS peripheral.

Features
  • Supports I2C and SMbus master interface with PRU-ICSS
  • Dynamic block mode read and write transfer
  • Contains PRU-ICSS source code for customization
  • I2C register interface emulation
