Re: Chrysler/Jeep - VES/SDAR emulation [VES - resolved!]

FYI, I just approved the above post, it's a link to someone who made a custom radio with a raspberry pi in a Jeep Grand Cherokee. asp13: thanks for the link, looks like a great project. One small request.. a little more context with links like this. I almost blocked it out of concern it was spam. Th...

Re: Arduino CAN BUS monitoring tool

Hello tandm87,
The board you're using is 8mhz clock, but you're trying to initialize it as 16mhz clock. See my adjustments above to modify the MCP library to allow 8mhz clock usage.

Thanks,

Re: Handling of Interval CAN Messages

poop713: I'd have a candump running in parallel with the cansend. That way you can see how it's going out onto the network. The candump/cansend commands don't block access on the port. I use this a LOT when I'm prototyping commands.

Re: Handling of Interval CAN Messages

can-utils is a linux based can library...

It works great on Raspberry Pi devices w/ the PI-CAN2 hat.

They even have a version w/ a 12v switching PSU so you can power the Pi from the car: PI-CAN2 w/ SMPS

Re: 2014 Dodge Charger

The OBD2 port CAN data is going to be a filtered sub-set of information available on multiple internal networks. It's mainly designed for engine/drivetrain diagnostics and can be enabled for software updates via special commands. The internal CAN networks ( like that on the back of the radio ) are t...

Re: Powering a device from the CAN bus

intern2016 I don't think this is going to work very well (or at all). The signal is differential, which means the + and - polarities reverse with the signaling of data. Further, there's almost 0 current carrying capacity via the CAN bus transceivers. I'd suggest instead, draw power from the 12v syst...

Re: Controlling vehicle by voice!

... I wonder if I can use something like this: http://www.lightinthebox.com/2-channel-12v-low-level-trigger-relay-module-for-arduino-works-with-official-arduino-boards_p903433.html?currency=USD&litb_from=paid_adwords_shopping ... That should work fine as long as the relay can withstand the current ...

Re: Controlling vehicle by voice!

Re: 12v relay on Arduino... While messy... you could use a 5v relay to activate a 12v relay..

Congrats on the progress! Any details you're willing to share would help someone else.. I'm sure!

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: 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.. ;)
