I already managed before to start it from terminal via startx /path/.run.sh
It worked perfectly and is a lot quicker to start this way then loading the whole x desktop

 

It'd be faster to eliminate X all together, which depends on if the program will run on directfb or gtkfb.

 

Tested yesterday with 14 gauges at once on the screen , and I still did not get lag or performance issues on my raspberry pi at all .

 

Congrats for the update Markus!

Like my previous pm, do you think it is possible to make a gauge skin like this design (it's more close to the original design with the oem gauge from dashboard)?

My idea (i have dl a double screen autoradio for the scale):



The ideal is to can switch with a gps/CD/Mp3 player and other stuff like alarm on temperature etc.. no? (maybe can make on linux?)

Like that:

 

It would largely depend upon the device you are using to display the screen and the operating system it's running. If you had like an android device that supported HDMI input for auxilary devices such as DVD players or something else, then it could work like that. Otherwise, you would have to compile the program for whatever device you're using -- which may be difficult to do while keeping the software/skins they use for their native interface.

Otherwise, making a skin like that would be pretty easy and straightforward.

 

To make a skin like this is easy ,just download megatunix and use the gauge and Dash designer ( make the gauge backround and rings black and delete the needle ) Make one gauge just static text and the other gauge a digital value .
I am actually busy making a skin like that at the moment

 

Raspexi Viewer has its own website as of now
https://sites.google.com/site/raspexiviewer/home

Can anyone of the mods tell me what i have to do in order to edit my initial post so i can always lin the latest version of Raspexi on the first post ?

 

YYYYYAAAAAAAAYYYYYYYY i just sent out my pfc for an initial tuning and hopefully once i get it back i can have my car ready to plug and play. i look forward to getting this up and running. thanks again Markus

 

Glad to hear that , please be aware that the boost gauge seems to show incorrect . Would be nice if someone with a analoge boost gauge cold tell me what their gauge is reading versus mine , so I can check where the fault lies

 

Does any one know what the mV range of the MAP Sensor is , and what voltage equates to which pressure ? This way it would be easy to have a workarround to fix the boost gauge

Regards

Markus

 

Raspexi is currently reading the intake pressure via the PIM reference in the advanced data table. PIM works on the concept of absolute pressure, thus, 0 is actually perfect vacuum. Atmospheric is near 10,000PIM. Thus why there is an issue with the boost sensor, as it's expecting to start from 0.

The PIM scale is something along the lines of:

PSI=(PIM*0.001422)-14.69

 

The PIM data as read from the PowerFC is a short word word in a raw format , to simply display that would not be very useful to the end user in a gauge .
As far as i can see from Kashima Kaele's source code he calculates it the following way to get from the raw PIM value to kg/cm2 :

Short word PIM consists out of 2 Bytes :
kg/cm2 = Byte1*0.0001 + Byte2*0.0256

I hope i get some time to look what powerfc.h in my program calculates after this weekend

 

unsigned short RPM;
unsigned short Intakepress;
unsigned short PressureV;
unsigned short ThrottleV;
unsigned short Primaryinp;
unsigned short Fuelc;
unsigned char Leadingign;
unsigned char Trailingign;
unsigned char Fueltemp;
unsigned char Moilp;
unsigned char Boosttp;
unsigned char Boostwg;
unsigned char Watertemp;
unsigned char Intaketemp;
unsigned char Knock;
unsigned char BatteryV;
unsigned short Speed;
unsigned short Iscvduty;

unsigned char na1;
unsigned short Secinjpulse;
unsigned char na2;


#define FC_ADV_INFO_MUL {1, 0.0001, 1, 1, 1.0/256, 1.0/256, 1, 1, 1, 212.0/256, 0.4, 0.4, 1, 1, 1, 0.1, 1, 0.1, 0.02, 1, 1.0/256, 1}
----------------------------------------PIM-------------------------------------------------------------------------------------------NA1------NA2
#define FC_ADV_INFO_ADD {0, 0, 0, 0, 0, 0, -25, -25, -80, 0, 0, 0, -80, -80, 0, 0, 0, 0, 0, 0, 0, 0}

So just had a look in powerfc.h

Currently the raw value of PIM is multiplied by 0.0001 first highlighted in bold

also 2 differential inputs are already defined , and would output the raw value
they are defined as na1 and na2 . (both highlighted in bold )
Unfortunately i don't have any sensors that i could hook up for testing

I am currently not really able to test at the car as my portable monitor backed up on me . Waiting for a new china ebay monitor now lol .

To explain the code a bit for people that want to play arround

FC_ADV_INFO_MUL
multiplies a short word or char with a defined value , in order to make a user readable format.
FC_ADV_INFO_ADD
adds a defined value to a short word or char in order to make a user readable format


So to implement and test SonicRat's formula

#define FC_ADV_INFO_MUL {1, 0.001422, 1, 1, 1.0/256, 1.0/256, 1, 1, 1, 212.0/256, 0.4, 0.4, 1, 1, 1, 0.1, 1, 0.1, 0.02,1, 1.0/256,1}

#define FC_ADV_INFO_ADD {0, -14.69, 0, 0, 0, 0, -25, -25, -80, 0, 0, 0, -80, -80, 0, 0, 0, 0, 0, 0, 0,0}

 

Hi guys

Here is the latest raspberry pi bianaries with redesigned gauges and 3 New Dashboards

https://drive.google.com/file/d/0BwI...it?usp=sharing

Changes :
Added SonicRat's formula in powerfc.h to have the Boost units in PSI

 

I just tested the latest binaries and can confirm that the boost gauge works now correct in PSI . I checked with the commander with engine off , and got -141 mmHg , when I plugged the raspberry in , I got -2.6926 PSI which converts to -139.2476275187600 mmHg . So should be accurate enough

 

lol Good work
Looks like I'm finally ordering a Raspberry Pi

 

Excellent work to you guys....looks very appealling...

 

Do you guys have any specific additions you're working on? Ie adding Aux input readings for AF ratio

 

I have looked at that , and it should be fairly easy to add , just wanted to fix the boost gauge first . At the moment I am busy to get my car finally on the road ( new bumper , fix rims ...) SonicRat also wanted to look into adding the analogue inputs .

 

hows the car coming along?

 

The car is actually comming along very well . Unfortunately my new bumper did not really fit . So I get a new one made . Got my rear rims back from refurbish. Next week front wheels . Lots of parts at home that need still fitting . Super pro bushings , HKS Hipermax coilovers ( should arrive today or tomorrow ) . Lots more parts on sea haha. Hope my registration will be sorted end of this month , after all the stuff ups .

 

Rear wheels look better now , front still to be "deblinged" lol

 

Thought it's time for a update again , compiled a fist "beta" image for the raspberry pi . Start up time is about 42 seconds and features a customizable boot logo . I also designed some new dashboards and gauges ( not yet uploaded )
Have a look

looks very good! where can i buy a screen (like double din?) to replace my current radio/storage case? thanks!

any rasperry version can run the soft?
