OBD MPGuino gauge

Thanks.
I tried different arduino version (19, 21, 22). Filelogger version was the same (V0.6). The compilation went O.K., but still can't upload to Arduino board.
I think there no need to uncoment #include <FileLogger.h>, because library will be included then it is chosen define useSDcard

How it fails?
The only one "fail" i know - if TX/RX left connected to board - code is not uploaded to board.

Sorry to say, but not this reason. (I can upload v193 without SDcard support). The only difference is compilation size (30050 v.s. 26624).
I bought Atmega328 with bootloader (installed "UNO"), but it's version is older.
Still trying.

How it "fails"? lcd is off? or what?
if problems with lcd - pins for lcd are changed if used with sd card.
some pins are used to sd card, and 2 lcd pins are moved, detailed description is in source coude.

With LCD is everything O.K. I moved 12->2, 13->3 and and code was changed - it works with version 193 without SDcard support.
I don't know that it is, but can't upload v. 194 (with SDcard support)to the arduino board from PC.

Hi Everyone, first time post here. I would love to be able to view oil temp and/or oil pressure as well, any ideas on how to implement this?

Hej Magister and all others,

I am working on integrating OBDuino on a ATMega 644 with 2515 CAN controller on board, which is quite fine: I have the Arduino bootloader working, LCD and buttons work.

2515 support, however, seems to have disappeared from the obduino32k code again, or was it never there?

When I check newest code, I only find ELM327 and K-bus support.

I suspect that Magister --- after testing 2515 in December of year 2008 --- seem to have dropped the issue again. Or maybe it just worked for him and he never reported back with code? I can only find posts from December 2008 indicating fine operation.

Magister, can you share your experience and code with me? Anybody else who can?

What would you recommend to me, change the whole thing to elm327 or go on fighting the lonely fight with 2515 (seems there is not much activity on that one anymore).

Best regards,
Stefan.

Is Si9243 good replacement for MC33290 and does Si9243 work with ISO14230-4 (KWP2000) protocol ?

There was connection schematic for Si9243 in previous page, but it was bit unclear for me.

[Magister]

@asti13 : sorry, CAN code with MCP2515 is close. ELM327 should be an easy take however.

@jkl : I think so, signals are the same, ISO14230 protocol is different in software only.

Is schematic below for Si9243 correct and are 100R and 1N4004 diode necessary ?
