Overview

Implementation of BiSS C Master protocol on Industrial Communication Sub-System (PRU-ICSS). The design provides full documentation and source code for Programmable Realtime Unit (PRU).

Features
  • BiSS C Master protocol running on ICSS
  • Interface speed of 1, 2, 5 and 10 MHz
  • 8x oversampled input capture
  • Line delay compensation with filtered sample point
  • De-bouncing filter on oversampled input
  • Variable frame format with crc check
  • Command (CDS/CDM) interface
  • Supports up to 100 m cable
  • Runs on AM335x and AM437x with ICSS
