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.
<section begin=IGEPv2 EXPANSION />
You have to connect the two boards like this:<br>
| 1 |-X X-| 1 |
| 2 |------------------| 2 | | 3 |------------------| 3 | | 4 |------------------| 4 | .--- .---
If this is your first time accessing CAN bus, check J702 jumper is not connected before follow this tutorial. If you don't have this jumper, don't worry because its function is only for testing.
If you want to send CAN data, use:
cansend can0 123#AABBCCDD cansend can0 123#R cansend can0 1F334455#1122334455667788 cansend can0 1F334455#R-i 0x123 0xaa 0xbb 0xcc 0xdd
On the receiver side, you must see the following messages:
can0 123 [4] AA BB CC DD can0 123 [0] remote request can0 1F334455 [8] 11 22 33 44 55 66 77 88 can0 1F334455 [0] remote requestaa bb cc dd
Switch roles and try it again

=== 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
