Re: Arduino CAN BUS monitoring tool

I seem to have determined the answer... Found in the MCP2515 datasheet, the full details of each config bit set by the CNF1|2|3 values. At this time, the following seems to operate quite well: #define MCP_8MHz_250kBPS_CFG1 (0x40) #define MCP_8MHz_250kBPS_CFG2 (0xF1) #define MCP_8MHz_250kBPS_CFG3 (0x...

Re: Arduino CAN BUS monitoring tool

Guys, Just want to share my tool to sniff CAN bus using Arduino + CAN BUS Shield. Link on github: https://github.com/latonita/arduino-canbus-monitor . This is an implementation of CAN232 serial protocol. Use it with software that understands it. First, I started to use CAN_BUS_Shield library to rea...

Re: How to connect with Dodge Caliber?

mrdennis87: Just for confirmation, are you saying that you're not getting the 'can init ok' message? Or is there some other indication? The reason I ask, your sample code would send data, not receive it, so I just want to confirm what you're seeing.

Re: How to connect with Dodge Caliber?

grafffik: I had a similar issue hacking the CAN bus on my RV w/ an Arduino and the SEEEDStudio CAN-BUS Shield. Banged my head against the wall for several days.. Until... START_INIT: if(CAN_OK == CAN.begin(CAN_125KBPS)) { Serial.println("CAN BUS Shield init ok!"); Serial.print("Resett...

Re: Opening up the forum...

It has busier times and slower times... Certainly even at it's busiest, it's not nearly as active as it was in the beginning.. Life it seems loves getting in the way of the fun.. ;)

Re: How to connect with Dodge Caliber?

I'm not intimately familiar with the Arduino CAN shield (have one, but haven't played w/ it yet).. but, I don't see anything in your sample code that sets the baud rate on the CAN bus. In your car, it could be either 83.3kbps, or 125kbps.

Try setting that and re-test.

Re: How to connect with Dodge Caliber?

Here's the web can log explorer that I wrote some time ago.

There are a few posts around the forum with some decoding of what certain can ids are for, message formats, etc.

I'm posting from my phone, or I'd put in more links for ya...

Hope this helps,

Re: How to connect with Dodge Caliber?

Hello graffik, Pins 5 & 6 are definitely the ones you want. You *can* technically connect to the OBD2 connector, but the data you get there will be much different than tapping directly into CAN-B via the Radio C1 connection. CAN-B contains all the comfort and control signals, including dash inst...

Why has my post not been approved?

Hey all... Sorry for the delay on moderation duties. I used to have a script which queried for moderation needs and it would email me, but with the upgrade to phpBB 3.1.x, that stopped working. It wasn't until just 30 seconds ago that I found this feature has been built in now! So... I've enabled th...

Opening up the forum...

So, back in 2006.. we limited access to the forum main contents to only those that were logged in. I think it's time we open things up a bit. I'll be changing the forum permissions to allow read from everyone, and of course, leave new posts to those that are registered. I feel this will get some bet...

Ok... the TDA7719 is a sexy little chip... I'm gonna order a few of them ( in case I screw something up ) and ... grrr... I gotta fly out to SFO at 6am... I'll spend more time on this in a few days when I'm back.. Thanks rtgree01 and nr0x. I'd love to get more details about your circuits, code, etc....

Re: PICAXE+ELM327

This is EXACTLY what I want to do my '14 JGC... It has the 8.4" UConnect w/ Nav.. which is a complete PITA. I found (and ordered) the PAC RP4-CH21 and the PAC-UP which are supposed to allow controls of all the functions, except the vented front seats (which I cannot live without). Further, they...

Re: Newbie Question (don't flame!): Door lock/unlock & ignit

It makes logical sense to have the capability to do this.. but, no guarantees they didn't accomplish firmware updates via a different method..

Re: Newbie Question (don't flame!): Door lock/unlock & ignit

It's my understanding that these commands are generally *not* available over the OBD2 port, with 1 exception. With Chrysler vehicles (my area of study), there is a gateway node that exists on all 3 CAN bus's.. Engine, Interior and OBD. With the right tools, Chrysler authenticates to the gateway and ...
