Hi Anton,

would Arduino UNO and Freematics CAN-BUS shield v1.2 enough to sniff 500kbs CAN bus of car? I mean, is 16MHz Uno is capable to process all CAN data without running out of the buffer?

I know about CANtact, but it uses more powerful STM32.

Thanks!

When using SavvyCAN, Arduino Nano with MCP2515 8MHz I keep getting HEX 07 back when sending dumps.

Write to serial -> 74 33 38 32 31 30 30 d (t328100)
Got data from serial. Len = 1
07 <<< Error

Savvy CAN v208

Can anyone help me?

By using CANable there is no problem

Hallo,

on Linux I used the follow instructions to create a can0 device in conjunction with sudo:

slcan_attach -f -s4 -o /dev/ttyUSB0
slcand -S 115200 /dev/ttyUSB0 can0  
ifconfig can0 up 

To dump the running traffic the following command can be used

candump can0

To delete the interface the following commands can be used:

ifconfig can0 down
killall slcand

On Debian or Ubuntu this command:

apt install can-utils

installs the neccessary packages.

Can you please add theses instructions to the Readme? 😃

So i have connected wires in this manner i'm able to do candamp can0 and receive packets correctly.

so i did candamp -l can0

and when I'm doing canplayer -I file.log it's not working :(

For CAN-BUS_Shield_V2.0, they change cs pin 10 to pin 9.
So you need to change this line:

And the debug pin 8 and 9 is conflicted

This is a great project, saving me a lot of time. Thank you.

Hello
I'm trying to use canhacker with canbus-monitor. I have two boards, an Seeed studio can shield and a MKR GSM with MKR Can shield, and the seeed studio can shield can conect to can hacker without problems but the MKR can shield can't even conect in the can hacker.

I changed the CS and INT pin to 9 and 7 respectively but it don't conect. I'm guessing that SAMD boards have another configuration for RS-232 but I'm not sure.

The reason that I'm trying to use the canhacker in MKR board is the machinery that i'm trying to conect. The seed studio can't read can messages in J1939 but the MKR board can, and I need to trace the can messages.

when sending from mcp2515+2551@16MHz to mcp2515+tja1050@8MHz
latter receives garbage.

other way around works well.

First try of integration does not work. Need to dig deeper into .travis.yml in coverity_scan branch

Hi I built you code onto an arduino UNO, with CAN module with 16MHz clock. When I used the CANHACKER software to send messages they do not get sent correctly. I put a loop back onto another comm port and the comport serial messages seem to be correctly formatted as per the Lawicel spec. If a message is sent with DLC of 8, no data bytes are sent. If the DLC is less than 8, the bytes are sent but are wrong. If I send a can message with the following: ID006, DLC7, 12,34,56,78,50,40,30, what is recieved is ID006, DLC7, 22,44,66,88,00,00,00. Any ideas? Hardware setup: I checked this with a Peakcan USB, and IXXAT tincan, both showed same messages. By the way great project, and a real good way for people to get a low cost can analyser. Hope this info helps. Regards

Hi

I found this library, and it appears to work great with my Nano, MCP2515 and SavvyCAN - except, no timestamp is passed through?

I see there's a list of command, I'd hoped they were commands I could send through the arduino serial monitor to enable timestamps (Z, Z2 etc) but no joy?

Would appreciate any pointers, thanks!

Hi.I have 2000 year mercedes.There are 2 can line.It works with canhacker which is 500 kbps but It doesn't work at all which is 83.3 kpbs

This is kind of weird for me to explain but here goes. When I first open the monitor the data is happily streaming away. If I do close "C" say to change the CAN rate say with an "S8" it returns fine with a CR as it should. Now if do an "O" nothing happens. I tried say with a "P" or "A" but then I get the bell. Now if I put it in listen only mode "L" and send a "P" it does a CR but do not see any data. I know data is still streaming because I can see it.

What am I doing wrong, help :)
Mike

just what i needed. Also do you know, does your can filter/mask work only in software ? why not use the hardware filtering options ?
