AUD with USB FTDI.


Hi all,

Just found this board a couple of days ago, been reading a lot, some topics are really nice.

Just wondering, reading all the stuff about the AUD port, everyone already tried interfacing the AUD port with an FTDI directly (FTDI FT232/FT245 or better for example FT2232H) ?

{ an FT232 can be switched by software to 245 mode as well.. or even to JTAG... or whatever IO you want/need }

This would mean that all the POWER for doing nasty stuff can be MOVED to the PC in stead of doing this in an extra CPU (micro controller).

And Every One has an USB port at this time.


Regards.

Keep on doing nice things....

Hi Guys...


See not much activity, responses.. but..

Wanted to tell you that the First USB-AUD prototype is ready ( single chip USB FT-4232h on 480MBPs)
And..
That I'm reading some stuff already..

And this with less then 300 code lines in C, at this time smile.gif  { tested on Windows and  Linux }

Still some work to do but.... but I'm getting there.

(not 100% accurate for the time-being,  from time to time it fails to read.., think it is a timing issue, but as said before .. .. but I'm getting there)

Chap.

Can you share your setup and tell us what you are working on? Sounds like you have some knowledge of electronics.

Hi Marc,


Where Im I working on? Well a lot of things, but for the DENSO AUD-stuff Im trying to build a cheap interface that can be used for a lot of things, basically its only a single chip (FTDI device), which would allow me to read/write a DENSO AUD-ECU.

How did I get here? Well Ive got a friend that wants to read/write his DENSO-ECU without investing too much. (At this time I have DENSO car-ecu living on my home-desk... to play/test with  ... )

This is why I started to build a test interface for reading the ECU by AUD.


At this time I used a little-proto-board of the FTDI-chip, that has 4 ports (that can be configured as serial port(s), and/or IO-port, and/or JTAG port, and/or SPI port, or whatever combination of these).

Its quite experimental, but seems that it will do the job. (Didnt have much time this week to continue on the AUD stuff, I do this in my spare time.)

Why didnt I use some other parts? Well I would like to have al the CODE running on a PC. (Because every one that is playing with ECU reading and writing at least has a PC  ... .and at least he is able to plug in an USB plug.)


Have I been playing with other CPUs/ ECU.. well, way to many to mention them all, because this Is what I do for living (hard and software development for CUSTOM boards) .. but some examples are, 80x86 (*) own made boards), 68000 (*), 68HC12/68HC16 (*), Hitachi-6303 (*), Fujitsu MBxxxx (*), and at this time ARM-9 [at 400Mhz..] (*)and some other less known CPUs. [ * OWN developed CUSTOM boards .. , hardware and software (bios-code {means assembly}  and applications { mostly in C/C++}, etc]

Hope to get some more tests/experiments on AUD .. (didnt have much time this week, was out of the country for my job ).


I'm I going to share ? the details ? Yes.. I want to share ... so everyone can have some  benefit from it.
But give me some time, need to make a better setup/configuration and software, way to experimental this time, would scare many (possible) users, if they saw the setup right now. smile.gif.




Regards,
Chap.

Thanks for the reply Chap. It is good to know that there are other ways of connecting to AUD besides buying high dollars factory boxes.

i have read/captured from the busa aud port using an 80 dollar parallax proto board and trea term using a bs2 program that rr wrote. All of the info is available on this board.......marc....

bump - any progress on this?
i am considering using ftdi chip to implement AUD on PC as it is not easy to buy a parallax board in my country.

If you want the ECU's read about the pin, but you'd need only modify the kernel.
When loading is the delete command, but if you have flashed the ecu, you can read it on the pin's also.

Anyone know if it has been successfully done yet? AUD with FTDI Cable? A little curious to give it a go for fun.

Brix, nice idea with the kernel! As long as you are connected after write you can read :)
Was it a mayor change or just removing the "erase" routine on connecting and loading kernel to ecu?

AFAIK ECUflash got develloper versions with a FTDI in bitbang-mode to read the AUD port.

But these versions are not for "endusers"

So no software or wireing around there
