In the last case, you have to connect the two boards like this:<br> Board IGEPv2 1 Board IGEPv2 2
→IGEPv2 EXPANSION
=== IGEPv2 EXPANSION ===
The IGEPv2 EXPANSION provides a CAN interface using MCP2515.<br>
In order to test the CAN interface you can connect IGEPv2 EXPANSION to a CAN device or network or to another IGEPv2 EXPANSION.

You have to connect the two boards like this:<br>

=== IGEP BERLIN ===
The IGEP BERLIN provides a CAN interface using MCP2515.<br>
Several tools are provided by socketCAN to use this controller:
*candump: dump traffic on a CAN network.
*cansend: simple command line tool to send CAN-frames via CAN_RAW sockets.
*cangen: CAN frames generator for testing purpose.
*canplayer: send CAN frames from a file to a CAN interface.
In order to test the CAN interface you can connect IGEP BERLIN to a CAN device or network or to another IGEP BERLIN.
You have to connect the two boards like this:<br>
Board 1 Board 2
.--- .---
| 1 |------------------| 1 |
| 2 |------------------| 2 |
| 3 |------------------| 3 |
| 4 |-X X-| 4 |
| 5 |-X X-| 5 |
.--- .---
Now you can set up the interface (on all boards when using multiple IGEP BERLIN <span lang="en" id="result_box" class="short_text"><span title="Click for alternate translations" class="hps">connected to a CAN network simultaneously)</span></span>:<br>
/bin/ip link set can0 up type can bitrate 125000
If you want to receive CAN data, use:
candump can0
If you want to send CAN data, use:
cansend can0 -i 0x123 0xaa 0xbb 0xcc 0xdd
On the receiver side, you must see the following messages:
can0 123 [4] aa bb cc dd
Switch roles and try it again
