PriiDash(TM): Enhanced Instrument Panel / Data Logger - Now Open Sourced!

Look up posts on engine block heater and grill blocking if you haven't. Good luck!

 

wTOBD is just what the OBD standard query returns. It seems to be synthesized from the other two temperatures. I don't know the exact locations of the sensors. From what I can see when using a block heater, wT is the coolant temperature in the engine block (warmer), and iceT is somewhere else (cooler). The two become pretty much the same, very quickly after the engine starts running.

 

OBD query is explained here:

OBD-II PIDs - Wikipedia

I don't have a lot of plots of the temperatures but one plot shows it peaked around 130 F when the ambient was 32 F. It dropped down to around 70 F after the engine starts.

 

2017-01 new version: Add csvtickinterval in INI xml file (default is to save an entry every 1.0 sec); Add Trip2 button and display in Main Window (works like a stopwatch with auto reset)

It looks like I had hard coded a few baud rates: 2M, 1M, 500K and 115.2K. I will add 921600. Are there any others I should add while I am at it? Thanks!

 

Thanks for the comments! Just to be clear, the drop down menu in the PriiDash main window only sets the baud rate for the USB virtual COM port. This is the part that I hard coded to a few choices and I will add a new choice of 921600.

The baud rate for the OBDII device is set separately: either manually or using AT commands in the command.txt file. Anyone can edit this file to change the AT commands, or as you said set it once and then don't touch it again. Actually this is documented briefly in the file and the ATPP commands are indeed commented out when the file is shipped:

Code:

// init and query commands for gen 2 Prius, max line length 1024,
// format: command 1,command 2,priority;//comments
// init commands are marked by priority 0
// query commands can be priority 1 or 2 or 3
// AT PP commands that only needs to do once for each new ELM327 compatible device
// ATPP01SV00,ATPP01ON,0;// turn on header by default (ATH1)
// ATPP03SVFF,ATPP03ON,0;// set default time out time (ATSTFF)
// ATPP0CSV02,ATPP0CON,0;// set default baud rate
// ATPP24SVFF,ATPP24ON,0;// turn off CAN auto formatting by default (ATCAF0)
// End of AT PP commands that only needs to do once
STI,STDIX,0;//show firmware version, device version
STSN,STSLCS,0;//show device serial number, PowerSave configuration
ATPPS,AT@1,0; //show programmable parameters list, device description
ATSP6,ATDPN,0; // set protocol to #6, check protocol should be 6
ATL1,ATH1,0; // turn on line feed, turn on header
ATCAF0,ATSTFF,0; // turn off formatting, set timeout in units of 4 ms; Flyer suggested using FF, may try shorter timeout in case Fujitsu goes to sleep erroneously
ATSH7E2,0521C3C442D3,1;//query inverter & MG Nm & T, 12V, brake light

Forgot to mention I will have to look into the WiFi port but it may be too big a project.

 

Hi the program has only fixed size windows. If you go to the previous few versions you can find different window sizes. You can also change the screen resolution of your tablet by going to Control Panel\All Control Panel Items\Display\Screen Resolution. Good luck!

 

Thank you for the interest. I actually haven't compiled for linux for a long time, even though initially I was using Ubuntu. If you go to
PriiDash(TM) - Enhanced Instrument Panel and Data Logger for the Prius and more
and look at the section "Note to Contributors", there are some general info on compiling. You can also look in the readme file of each version. Earlier versions use fewer 3rd party libraries so may be easier to compile. Good luck!

 

Ok I looked in the readme file for that version and it says linux needs to recompile. Also the size of the priidash_Ubuntu file is only 99 kB - seems too small. Well after further digging it looks like even the earliest version says linux needs to recompile. So unfortunately it looks like I have stopped using Ubuntu early on.

For the resolution, I think the MFD version window size is about 1050x700, and the previous one was slightly smaller than 1280x768. I don't think you need a very powerful computer to run the program. I am using a netbook (got one before they went extinct). Good luck and let me know if you still need help.
