Status bar from canbus please

janis

I have basically same problem. My car shows all kind of info in vehicle setings. But none of it can be displayed on widgets and statusbar. I wish i can display average fuel consumption and range left to drive in widgets but it is not possible.
I have bmw e39.

The water temperature in the upper right corner of the status bar currently only supports OBD data and does not read from CAN bus.

Hi!
Same question/feature request here.
For now displaying water temp in status bar is only possible via OBD, so in order to show it there I need to install OBD adapter. BUT water temp is available via CAN and can be displayed only in widget.
I want to display water temp from CAN in status bar so I don't need to install additional OBD adapter only for water temp. I don't want to use separate widget for this as I only interested in water temp in it.

So is it possible to add support for displaying water temp is status bar from CAN?

From the outset, the design requirement was to display only OBD data. Reading from CAN would be very complicated, as different brands and car models have different protocols and different ways of reading coolant data, but OBD data is standardized.

Mikescotland

DUDU-Meng @Feym That is completely untrue answer.
Already they are information from canbus on the status bar (my car screenshot below), on some other cars there are also fuel levels etc.
Outside temperature is different on canbus on almost every car and yet it's displayed without any problem.
Canbus messages are translated by canbox and canbus apk in the system. Then output from the canbus apk is standardised for ALL cars to distribute as same values into the FYT system. So "because it's different on many cars" is completely irrelevant in that case.
Somehow speed canbus data also vary between cars, yet, you're able to pick canbus speed values for widgets.
I suspect problem lies somewhere else - status bar is a FYT feature and as duduOS isn't really an OS but just skinned interface, Dudu devs can't really change anything important on status bar, as FYT doesn't provide source code even for headunit manufacturers as far as I'm aware.
But be honest instead of coming up with strange and untrue logic for the problem.

But water temp from CAN is already displaying in widget. Is it complicated just get same data and show it in status bar?
Not replace OBD, just add additional choice in settings to get it from CAN as widget has.

This request can be recorded for later discussion by relevant personnel on whether to add it.

Mikescotland The status bar you see is not the FYT status bar. It is our own. We can modify and develop the status bar information at will. Which FYT system have you seen such a sub-navigation bar?

Please provide screenshots of the system information. The coolant temperature values require verification. Each vehicle model requires separate protocol verification.

DUDU-Meng
Understood.
Please record this request.

Me uno a la peticion, mi vehiculo en pantalla original puede mostrar temperatura de aceite , temperatura de agua refrigerante , consumo medio de combustible , etc.
Obviamente todo esto lo hace originalmente con canbus de serie .
La radio Dudu7 no muestra ninguno de estos datos .
Sería muy interesante e importante que estos datos se reflejasen vía Canbus en DUDU7 y asi evitar tener que usar OBD2 .

We have not yet unified the data management here, and will integrate OBD+CANBUS+sensors in the future.

Mikescotland

DUDU-HUANG hopefully soon. Just discovered that RPM in triggers is also taken ONLY from obd not can. This system is so fragmented...

KravtLab

I'm also joining the request. I would like to see the CANBUS data in the status bar.

Mikescotland

DUDU-Meng I don't have this in the vehicle info as I haven't yet discovered Uart address for Toyota Rav protocol (and my car runs custom canbox as no canbox available for my car). However, I've got RPM from canbus and as we discussed earlier, all tasks take RPM from obd only as a trigger.

I use the Raise-Toyota-HARRIER canbus profile. Most Raise-Toyota-....... profiles have a similar data packet ID encoding for Android. I use a custom-made canbus adapter. For example, the engine temperature has a packet ID of 7D. The packet contains 4 bytes: D2 is the engine water temperature, and D4 is the oil temperature.
Is it possible to display the oil temperature in the status bar?

DUDU-Meng

Mikescotland
Since this feature requires data verification and addition for each vehicle model individually, which involves a significant amount of work, you may prioritize providing your vehicle model. This includes the CANbox capable of reading water temperature from the vehicle information and the selected protocol ID. We can prioritize adding it for testing.

Моё мнение.
DUDUOS это мультимедиа, музыка, видео, развлечения....
OBDII это диагностика автомобиля у которой программы занимают до 900 MB данных, и это относится к ремонту автомобиля.
Это два разных варианта. Если их совместить то не хватит мощности процессора, не хватит места в накопителях.
Харашо работающая мультимедиа это прекрасно. А если я хочу диагностику машины я еду в автосервис.
Извините за премоту.

Функция, которая обсуждается в этой ветке, не займет много ресурсов, практически всё уже есть в магнитоле. По простому при выводе температуры в строку состояния нужно взять значение из другой ячейки памяти, где хранится значение полученное по канбасу. Ну и прописать в меню магнитолы переключатель, откуда брать данные.

Mikescotland

KravtLab thanks for the info. Can you please paste full line for this info there is also function byte required in 7d, it's a missing piece for my custom canbox. Thanks.

The top water temperature module now supports protocol integration. Select the system integration option under Peripherals - OBD.
Please test it.

ID=7D - D1 : D2 : D3 : D4
D1 = 09 (function byte)
D2 = engine water temperature (for example - hex 28 = Zero degrees Celsius)
D3 = ?
D4 = oil temperature
