These will filter received messages and only messages matching one (or more) filters will be loaded in ram
The can peripheral on stm32 mcu's can be configured to run in loopback mode.
This article describes step by step how to create a project for can in loop back mode on an stm32 mcu Considering the growing interest in the stm32 can peripheral in embedded applications, this article aims to explain the main features of the protocol and provide comprehensive information on the topic. This tutorial introduces can communication using stm32 microcontrollers You'll learn about the can protocol fundamentals, how to configure the stm32's bxcan peripheral, and how to send and receive messages in your applications.
The stm32 can example program shows how to configure and use the can peripheral of stmicroelectronics stm32f103xx microcontroller The can controller is initialized for 500 kbit/s. This article gives information about the linux® controller area network (can) framework
