I'm working on my own DIY CAN reader with BLE https://github.com/timurrrr/RaceChronoDiyBleDevice
I've noticed that some channels look smooth-ish (such as speed, rpms, accelerator pedal position), but at least the "brake pedal position" channel has jagged edges. See the cyan colored line in https://imgur.com/FEmqGO5
as an example.
Is this something that RaceChrono handles incorrectly?
Also, I can read Lateral acceleration, as well as Longitudinal acceleration, from the CAN bus and send to RaceChrono.
There are two problems with those:
1) When I use either of them in the G-meter for the overlay, nothing is displayed.
2) They are noisy, see https://imgur.com/WtwTsPR
. Could RaceChrono have some configurable smoothening for data channels in post-processing? I guess I could apply some smoothing in my CAN reader, but that would introduce some offset/delay. I'm sure many accelerometers (and probably other data channels) would benefit from such a feature.
The G-meter on the overlay cannot handle anything else than GPS data. It's on my TO-DO list to overhaul this (and some other gauges too). It needs a new overlay editor though.
RaceChrono does have smoothening and a lot of other filters. It even have a filter to fix the "jagged" data. Unfortunately I haven't figured out how to incorporate this to the UI yet. Instead, these filters are only used in hard-coded manner for specific things, like the accelerations and lean angle calculated from the GPS.
So for data channels such as oil/coolant temps you suggest only sending them when they change? Or could some smoothening be hard-coded for them too?
Re: new overlay editor — curious what's the difference between the accelerations calculated from GPS and the ones from accelerometers when it comes to the UI. As long as I can provide both lateral and longitudinal accelerations, I wouldn't expect any difference when it comes to the UI...
@aol_of_RaceChrono, are there any update about that?
I'm using OBDLink LX and @timurrrr's method so that I can get CAN-Bus signals from my BRZ(ZC6). Thanks, timurrrr!
Same as timurrrr, I want to display G-meter by CAN-Bus acceleration signal.
I'm waiting for the release.
