===================================
UPDATE 11/24/2017
This Library is being withdrawn, the underlying CAN API in MBED is insufficient to properly support NMEA2000, and there is no indication of that changing in the near future.
Anyone using this library must proceed with great caution, and likely will need to provide a patch or custom CAN driver.
__cREF: ARMmbed/mbed-os#4090 __
=======================================
~~
This library provides support for MBED environments hosting ARM CPUs. It allows access to the NMEA2000 library using MBED devices internal CAN controllers.
See https://github.com/thomasonw/NMEA2000_mbed https://github.com/ttlappalainen/NMEA2000
Though any MBED with internal CAN controller should work, this has been tested primarily with the STM32F072RB CPU
This library is in support of ttlappalainen's NMEA2000 library. See the NMEA2000 for more examples. Include this library in your build files.
can1 must be defined and initialized externaly to this library
All serial I/O will use stdout and stdin, see example for how to 'redirect' those to a different serial port.
The CAN port is fixed to can1, which must be initialized before NMEA2000.Open() is called. Make sure to also take care of any transceiver sleep pins, if your hardware is so designed.
MBED libraries are of varying quality. Review carefully the underlying MBED CAN libraries, the quality of them are suspect with major errors being found even in 2017.
FastPacket protocol in NMEA2000 requires CAN messages be kept in as-sent order. At present this is not assured in the MBED libraries. Refer to NMEA2000_mbed.cpp and open() to see detail on how to address this. Do note that these corrections may well require you to locally edit your MBED libraries, refer to the current status of pull requests to see if this is needed.
- At present the STM32Fx CPUs have a correction identified, but not accepted into MBED libs
If you make an additional correction to a new CPU, please edit this readme file as well as the lib source code.
Refer to the MBED CAN documentation for hardware configuration.~~
