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
This repository provides two crates:
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
It contains traits meant to be implemented by target HALs in order to resolve platform-specific details
MCAN HAL was developed by Grepit AB and financed by Volvo Cars Corporation
