CAN 2.0 interface I/O

sigtrm · Post by **sigtrm** » Mon Mar 23, 2015 7:40 pm

Let's say I have some sensors which output CAN2.0A in Motorola format( I have full frame spec) how can I configure RCP mkII for use with custom sensors/CAN2 protocol.

Also how can I setup second CAN to output CAN 2.0 custom frames?

I suck at searching or I just can't find documentation for this, it would be nice if so one could point me to proper docs.

Ok, found some resources:

http://www.autosportlabs.net/RaceCaptur ... g_Examples

Should be enough, but is it it? or there is some more?

For integrating a new CAN system this is the essential guide:

What kind of sensors are they?

That is what I wanted I think.

I attached CAN spec from Brighwater. I will share code if/when I implement those;-)

*BTW, I was allowed to share it with RCP community.

Fantastic. Use the mapping framework seen in the integration guide to develop the mapping - post it here and we'll review.

Thanks for sharing!

Ok, added to CAN database. thanks again! http://autosportlabs.net/CAN_Bus_databa ... chnologies

Thank you brent, I am implementing this now, will post soon.

You switched Mul with Add in table on wiki;-) Multiplier can't be 0 obviously;-)

Have few additional questions:

1. After defining virtual channel I do not see it on the list Select Channel. I can see my channels only on last screen where all the values are listed.
2. Can you consider external editor for LUA? The one from scripting tab...($%$$&^. For example when I use

Code: Select all

print&#40;"DEBUG\n something"&#41;

it prints ok with newline, but after closing and reopening RCP code editor looks like this:

Code: Select all

print&#40;"DEBUG
 something"&#41;

3. Is debug window is on the same UI thread with Script Editor window? Because it is so slow when Poll is checked.

Thanks for catching the error. Fixed! http://autosportlabs.net/CAN_Bus_databa ... chnologies

we don't yet have an external editor - that simply looks like a bug to fix! You can print newlines with a println() also.

We do have some optimizing to do for the log window when there is a lot of data. You can also view the log via a terminal program, following these instructions: http://autosportlabs.net/CAN_Bus_logger ... al_Program

For the virtual channel update, we are fixing that in the 2.8.0 / 1.3.0 release of the firmware, coming likely within a week.

Thanks,
3 more questions:-)

1. Why 10 vchans limit? 4 wheels x temp+pressure and I have only two left:-(
2. Can I update wiki myself or do I have to post here or send to some email?
3. How much Lua is supported? Which libs ?

Here you go:

1) Actually, in the latest firmware you can set up to 30 virtual channels - just fixed the Lua documentation.
2) We have registrations constrained due to spam. Please email us at racecapture@autosportlabs.com to be a wiki contributor. Thank you!
3) Only the basic Lua libraries are supported and some math functions. We're looking to add the bitop() functions as well in a future firmware release. If there was a specific function you were looking for, let us know!

I updated wiki a little for Brightwater TPMS, I will fix and clean it ASAP:

Thank you for updating the information!
