Second CAN port on EMX Development System

Hi, i’m building a CAN gateway for a prototype but on the EMX10-DS-129 only one CAN port is actual
on the board, for the second port, can we use a gadgeteer module like the CANDW-GM-311 for this?
Are there people having exprerience with these modules in automotive solutions? (SAEJ1939)


Welcome to the forum!

Looking at the lower left corner of the EMX development system you will see a header. This header exposes the pins for the second CAN channel on the EMX module.

You could wire the DW CAN module to these pins.

Ok, thanks Mike.

@ David Did you find any information regarding the implementation of SAEJ1939 on .netmf?

@ leforban - Yes,why?

Because I am interested in implementing CAN SAEJ1939. In fact I want to retrieve data from A/D Converter from Axiomatic:

Do you have a tutorial or any advice?

A brief and global overview on 1939 :

But imho you don’t really need much knowledge about 1939 to use on netmf.
You probably set a filter on CAN listening to the ID of your output controller and broadcast messages
in the format specified in the output controllers manual.

At most you need to have a deeper look at the PGN and SPN definitions that you will actual use.

Ok for now, I am just playing with EMX and a CAN Usb, things seem easy but let’s wait for the axiomatic modules …
