MCAN

The M_CAN is a CAN IP module that can be realized as a standalone device, as part of an ASIC or on an FPGA. It performs communication according to ISO11898-1:2015. It supports Classical CAN and CAN FD (CAN with Flexible Data-rate). Additional transceiver hardware is required for connection to the CAN physical layer. The message storage is intended to be a single or dual-ported Message RAM outside of the module. It is connected to the M_CAN via the Generic Master Interface. Depending on the chosen integration, multiple M_CAN controllers may share the same Message RAM. The Host CPU is connected via the 32-bit Generic Interface.¹

Repository content

This repository provides two crates:

mcan

It contains a platform-agnostic HAL for MCAN, with support for

• classical CAN and CAN FD with bitrate switching
• message transmission using dedicated buffers, FIFO and priority queue
• message reception using dedicated buffers and two FIFOs
• message transmission cancellation
• filter settings

mcan-core

It contains traits meant to be implemented by target HALs in order to resolve platform-specific details
