Version 198? - then we will soon reach a milestone (version 2.0.0) What will that offer Eimix? - Graphical display?

Graphical Display would need to deviate from simply pushing digits to the display, and actually drawing the numbers / characters / images on the screen.

It can be done, but a different kettle of fish to the HD44780 displays.

Hi,

I can't get version 198 to work properly. Problem is initialization after the engine has been stopped. The OBDuino never realises that the car has been started. It work perfect with release 190. I have configured the init-params exactly the same - but haven't solved the problem.

Maybe someone can figure it out. I have set these params:

#define useECUState
#define DisconnectECUIfRPMIsZero (new, not in version 190)
#define do_ISO_Reinit
//#define skip_ISO_Init
#define carAlarmScreen

What happens is that - when I connect the device to the car for the first time it starts polling for the ECU. I start the engine and communications come up perfect. When I stop the engine (the OBDuino saves trip data), and start it later - the OBDuino never comes to life again (this works fine in ver. 190 with the same settings). I have noticed the following - if I disconnect the OBduino and connect it again - it works perfect (of course). It also comes back to life - if I - when the engine is of - tampers with the menus.

Can anyone explain this behavior? Can it be because of the "DisconnectECUIfRPMIsZero"? - as I read this - it should help the OBDUino to be sure that the car is stopped.

I would very much like to be up to date with the newest software - it is just being better and better

I use:
#define ISO_9141
#define useECUState
//#define DisconnectECUIfRPMIsZero
#define do_ISO_Reinit
#define skip_ISO_Init
#define carAlarmScreen
In my car (VW Passat 1999; gasoline, ISO_9141) it works. Then have tried #define DisconnectECUIfRPMIsZero, I has similar problem.
But necessary uncomment both: #define do_ISO_Reinit
#define skip_ISO_Init (I think, the checking at line 986-991 (ver 198) (987 #if defined skip_ISO_Init) is not working)

Hi Dar,

Thanks! - I tried with your set of parameters - and it works!

thanks for clearing up.
#if defined #ifdef and similar are not always catched and processed by arduino compiler

i will try to work on this.

no milestone and it is more like 198.0.0 not 1.9.8

Graphical display would require moving to arduino mega

i was looking at nokia 6021 phone display, but it needs micro connector (i do not have it) or very precise soldering (i'm not so good).

somebody could work on hardware analysis if display would be available ~ 10-15$ it would be worth trying.

Hi folks!

When I read about the support for the buzzer, I was thinking about if the following would be useful:

Where I live we have three type of roads each with a speed limit.
One is for city-roads, another for normal country roads and a third for highwayroads.

How about having the OBDuino giving:

One short (0.25 second) beep when passing the first speedlimit. Two short beeps for the second speedlimit and (you guessed it ) three beeps for the third speedlimit.

And eventually you could have a configurable max. speed (max. speed you want to drive - not the cars max. speed). When this max speed limit is reached the buzzer should sound constantly until the speed again comes below the max. speed limit.

What do you think? Will this be a sound inferno or could it be a help to the driver?

come on guys

why do I get zeros in all PID's?

code is 193 together with elm327. car uses ISO protocol (not sure which one)

halp? pls?

Hi guys,

Got a new idea. Hope someone will implement it

Idea #1: I think it is annoying that when you want to switch from one page to another you sometimes have to go through up to 4 pages to come to the one you want (worst case). I would like that it was possible to browse forward and backwards. Therefore I suggest that the brightness adjustment is moved to the display menu, and the that the right button is used to browse forward through the pages and the left button is used to browse backwards. What do you think?
