The device can act as an interface, a gateway, or bridge between all its channels. An analogue
input and a digital output enable the user to interact with external peripherals.
There are two options to use the interface:
•
A universal "stock firmware" interface for Ethernet-CAN(/FD), Ethernet-LIN, USB-CAN(/FD),
USB-LIN with the help of the open communication protocol (see [1]) over Ethernet (both TCP
and UDP) or USB (VCP).
•
An interface with a user firmware, allowing the user to write his own application on top of
the MACH-ETH device.
Firmware can be developed in C/C++ and can be transferred into the device over USB, ETH or
a standard ICSP SWD interface, which also offers code debugging. The device is based on a
STM32H7 Arm Cortex-M7 MCU and comes with a free-of-charge IDE, GNU C/C++ compiler,
and programming examples.
