Hey Qer,
Is there an ETA on Junior yet?

Is there an ETA on Junior yet?
Shane
EVnetics Soliton software version 1.2
Yep, we're closing in to a new software release despite that 1.1 just came out. Reasons for that is mainly that Junior is on it's way and the 1.1-release doesn't support it. However, it's a bit boring to do a new release without adding any fun feature I decided to add some logger information about what's limiting the motor current (if anything, of course) so you don't have to guess anymore. Here's a run on my test setup which, btw, is a huge mock-up. There not a motor in sight on my work bench so you don't think it's a dyno run.

The controller starts up at 6 seconds rather than the normal 1 seconds, otherwise the network wouldn't have time to connect before precharge starts. Here's some interesting excerpts from the logger.txt-file that's the base for the graph above, the columns are:

So there'll be a new software release within a few days unless something unexpected happens.

So there'll be a new software release within a few days unless something unexpected happens.

Yeah, "soon".
No, there's not a specific date (unless Tesseract has forgotten to tell me), it'll simply be released when it's done and we're satisfied with the test results etc. 1.2 is the first software release that support Junior (Junior and S1 run exactly the same software to make my life easier) and I think Tesseract has, or soon will have, all the hardware for being able to start testing things.
From testing to producing will of course not happen over night but since it's pretty much a downscaled Soliton 1 and things are coming together fairly nice I don't think it will be even half as tedious as all the last "small fixes" we had to do to the Soliton 1...
But, well, soon.
Uhm. Well, we're planning it but don't expect that one quite as soon...
We don't really have an official timetable or schedule. We do have a priority list, but even that seems to get changed on a daily basis. That said, our first priority is satisfying demand for the Soliton1 - something which has been a bit of a challenge over the last month to six weeks both because of the hardware revisions I've had to make to accommodate the expanding product line and a weird uptick in orders.
Anyway, I received the 4th revision of the pc boards for Junior a couple weeks ago but I just haven't had the chance to test them yet. That's partially because we need to machine a new enclosure. Once that gets done I can start the destructive testing to determine the safe operating area, then the non-destructive testing to confirm it, then it will more or less be ready for release because the hardware is a known quantity and the software is more or less the same as in the Soliton1 (just different current limits and temperature scaling).
Big Sol... well... it's still on the schedule, it just isn't a high priority. We are pretty much working in tandem with toddshotrods on this, and he, like us, is very much afflicted with the tinkering/perfectionist genes

Sorry guys, I'm on their side. EV racing is still gestating right now, and there isn't exactly a lot of need/demand for it yet anyway. The current crop hasn't even exceeded the limits of the Zilla 2K-HV yet.
Yes, but not drastically so. The UDP-package contained 14 16-bit words (most of them unsigned) in 1.0, in 1.1 it was extended to 16 words and 1.2 has also 16 words but one has a slightly altered function. So this is the complete format:
- 2 NUL-bytes
- Running time (0-59999 ms)
- Running time (0-65535 s)
- 12 Volt supply (see comment below)
- Pack voltage (V)
- Motor current (A)
- Tempreature (C * 10, signed)
- Input 3 (see comment below)
- Input 2 (-"-)
- Input 1 (-"-)
- Throttle (A)
- CPU-load (divide by 128 for percent)
- Pulse width (divide by 10 for percent)
- RPM (not that it works very well in 1.0, but it's reported anyway)
- Debug word (ie ignore, introduced in 1.1)
- Mode (see comment below, introduced in 1.1)
So, some of those values are dumped raw from the internal format rather than converted, that's why they're a bit awkward to use. The actual 12 Volt supply voltage can be calculated by taking the 4:th word, multiply by 0.00025939941 and adding 1. The actual input voltages can be calculated by multiplying by 0.000080645.
The mode word has changed format between 1.1 and 1.2. In 1.1 it only reported errors as a signed byte (high byte was always 0) where negative values indicated errors. In 1.2 the word has been changed to a bit field with the following functions:
- 15: High motor voltage
- 14: High motor power
- 13: High motor temp (snap switch input)
- 12: Over REV
- 11: Low pack voltage (or LVC BMS input active)
- 10: High pack current
- 9: High voltage high current (ie if pack voltage is above 310 Volt AND motor current hit 900 Ampere)
- 8: High controller temp (this will ONLY indicate if the current is detoriated due to high temperature, not that the temperature itself is high)
- 7: Slewrate active
- 6: Throttle blocked (for example when shifting reverse-forward)
- 5: (not used)
- 4-0: Status/error codes
The status/error codes are:
- 0: Starting up (software initializing etc)
- 1: Precharge phase (precharge relay active)
- 2: Engaging contactors (the two contactors are activated sequencially to avoid a too big current rush on 12 Volt)
- 3: Wating for start signal (if that's enabled as an input)
- 4: Throttle not in zero position
- 5: Running
- 6-20: (not used)
- 21: Zero voltage after precharge (did you connect that Anderson connector)
- 22: Pack voltage too low after precharge (might indicate a shorted IGBT)
- 23: Faulty throttle signal (either unconnected or short circuited)
- 24: 12 Volt too high
- 25: 12 Volt too low (a DC/DC is a good thing...)
- 26: Pack voltage too high (ie above 342 Volt)
- 27: Pack voltage too low (which probably will only show if you blew a fuse or something)
- 28: Motor terminals short circuited (or your motor just went up in a plasma ball)
- 29: Out of memory (I hope to never see this in a log...)
- 30: Software error (ditto)
- 31: Controller shut down by user (either in web interface or by turning off ignition)
If you mask the status/error word with 0x1f (or 31, 00000000 00011111 in binary, for those of you that are hexadecimally impaired
) the codes will be the same in both 1.1 and 1.2.Please note that there's an extra debug feature in the log format! If the first byte isn't NUL the controller hasn't sent a log package but a clear text NUL-terminated ASCII-string of arbitrary length! Most (all?) of these are removed in 1.2 since the mode bit field satisfy the same need in a more elegant fashion, but it's still worth to make sure the code can handle it if they appear since many versions of the software actually does transmit them every now and then.
