Foreword The use of reprogrammable memory technology in vehicle electronic control units (ECUs) has increased in recent years, and is expected to continue in the future. Use of this technology has increased the flexibility of being able to use a single ECU hardware part to be used in many different vehicle configurations, with the only difference being the software and calibrations programmed into the unit. Reprogramming of those ECUs in the service environment also allows for ease of field modification of system operation and calibrations. Variations in reprogramming capability and the multiple tools necessary to reprogram vehicles are a burden on aftermarket repair facilities that service different makes of vehicles.

Simple Open Source EtherCAT Slave ==== SOES (Simple OpenSource EtherCAT Slave Stack) is an opensource slave stack that is very easy to use and provides a small footprint. It is a good alternative to more complex stacks on the market. Overview SOES is an EtherCAT slave stack written in c. Its purpose is to learn and to use. All users are invited to study the source to get an understanding how an EtherCAT slave functions. Features as of 1.0.0: - Address offset based HAL for easy ESC read/write access via any interface - Mailbox with data link layer - CoE - Object dictionary - SDO read and write for all sizes including segmented transfers - Easy portable C-code suited for embedded applications - Fixed PDO mapping - FoE with bootstrap template - Support for Little and Big endian targets. - Polling for interrupts
