CAN-Message with EB018 CAN-Board

[P455E]

Hey guys,

I want to send a simple message from one Arduino Uno to another one. I´m using two Arduino Uno R3 which are connected with the EB093 Shield and the EB018 CAN-Board.
The code just initialises the CAN, reads the switches, send a Buffer with this information and show a LED at EB018. What I´m not sure about, is the setting of the Patch-System and how to set the Jumper-Wires. The Board has 5V, but there is no Signal sended by the Transceiver and no LED blinking.

Actually it looks like this:
- 2-/INT
- 3-SDO
- 4-SDI
- 5-SCK

The CAN is connected to PortB Pin 2, 3, 4 ,5 (Pin2 has been connected to PortE Pin 6 at the beginning).
You can find my fcfx-file in Posted Attachments to check.

Can anyone help me?
Would be very nice if you have an idea, what i´m doing wrong.
Thank you!

Hello,

Please can you try this and let me know how you get on. I've changed the CAN component connections slightly for you.

The EB018 board must be in jumper settings C and 2, connected to Port D8-D13,

Because of the weirdness of Arduino ports you will need to wire across the connections on the EB018 board using single core wire as follows.

2 - /CS
3 - SDO
4 - SDI
5 - SCK

/INT can be left unconnected.

If everything is ok then the two LEDs on the EB018 should flash alternatively.

Thank you Benj, the LEDs are flashing now and the code is running! But there is still no CAN-Message sended and i think that the Options for Tx and Rx buffers aren´t correct.
This isn´t described in the examples I found.
How I have to set them in Transmitter and Receiver?


Sorry for that annoying questions, but I´m working on it for weeks now and don´t know whats going wrong.
Thanks you.

Hi
Your RX Mask and Filter settings don't match your TX ID
So I would suggest first changing the RX Buffer 0 Settings from "Use Mask and Filter" to "Accept All" in your CANrx project
