I'm using a Arduino Uno as ISP and when I try to write the datalogger v3 sketch I get the following:

avrdude done.  Thank you.

Any ideas what is going wrong?

Well found the following site http://www.gammon.com.au/bootloader
And the tools under https://github.com/nickgammon/arduino_sketches work to flash the bootloader and the Atmega_Hex_Uploader (http://www.gammon.com.au/forum/?id=11638) needed some fixes but it did help to program the Data logger with v3.
I have not tried it out in my car, but it does write log files to the SD card.

Cheers,
Jason

Hey Jason,

i happen to have the same error, appart from the memory location and the value to be different. Verification error; content mismatch.
did you test your solution? Are there some steps you are willing to share to help me out?

Stanley, maybe any help here?

thanks,
Mark

Hi Mark,

Flashing the datalogger v3 sketch was successful, my problems now are that the OBD data is not being read correctly. I believe the cause of this is my car (Toyota Prius model 2010). The bus always is powered in my car. So I guess when I plugin the Data Logger it startes and isn't able to read data because the car is not on en therefore fails and does't try again.
When I plugin the data logger during driving ("Kids do not try this at home, we are professionals!") and I have the App running on my ipad I get one reading on the "Live data" part of the app. But then it stop sending OBD data.

I need to find some time to create my own debugging script to see what is going on. I will have to create something that keeps on trying to read OBD data and logs to the SD card and/or log it over bluetooth (BLE) so that I can look at live on my ipad with a bluetooth terminal app.

Enough of my problems, do you want me to write up the steps I did to get the datalogger v3 sketch on the datalogger with the "Atmega_Hex_Uploader" and which fixes I made to it to get it working?
Just let me know.

Cheers,
Jason

Do you know what protocol (CAN or others) your car uses?

Hey Jason,

thanks for the offer, i managed to fix it eventually!
I unplugged the SD card from the obd logger and it programed like a charm. no errors.
I do have another problem (as if it was not enough).
The logger makes a large amount of csv files, with like +-20 data points. and other times it makes a file of 1gb, 800mb. this thing is so unpredictable...

Hey but i can now (eventually) program it, after a couple days of full time trail and error. Mainly driver issue of the programmer i use...

It should be ISO 15765-4 (CAN 11/500). I got the info from http://www.obdkey.com/fv_toyota_prius_2010.asp

I have tried to set OBD_ATTEMPTS in config.h to 0, but that doesn't help. It just makes all slow.

Code: Select all

/**************************************
* Hardware setup
**************************************/

// number of attempts of connecting OBD-II (0 for always)
#define OBD_ATTEMPTS 3
