Thank both of you for your answers.
Unfortunately my car does not have ODB.
Even if it had it does not have a multiplexed bus (such as CAN) so I would only get info from the engine control unit, which I am not interested in.
What I want to log are several chassis parameters, such as :
- suspension travel (one sensor for each wheel)
- tire temperature (3 sensors per wheel)
- yaw acceleration
So basically even with a car where every electronic unit sends something I would not get those informations, since AFAIK no production car comes with those sensors installed as standard anyway (well your car has a yaw sensor if it comes with ESP but this info is not sent over CAN or ODB).
And 10ms is what I need, whether or not this is reasonable using an Arduino remains to be seen but if it's not I'll just have to use something else
I mean at work we log some stuff with sub-milliseconds periods, some others with 1ms, 2ms, 5ms .. well you see my point.
So back to the original questions, am I right to assume shields can be stacked ?
Is there some limit to the number of shields one can use ?
Are some shields incompatible with some Arduinos ?
I did not find any info on the site, so basically any pointer would be greatly appreciated !
