Web1 Purpose []. This article describes how to send/receive data on a SocketCAN interface using the can-utils package.. The can-utils contains some userspace utilities for Linux ® SocketCAN subsystem. It is integrated in the SDK for the STM32 microprocessor Series. Only cansend and candump are used in this example, but many other tools are available …
