Here is wikipage with schematics:

also page ti theory of operation:
https://github.com/tomaskovacik/VAGFISReader/wiki/Theory-of-operation
When writing to the cluster, no external components are required,the cluster has all these components inside.
I think, this apply for pre-CAN-BUS cars only, check sticker on your radio, if there are 3pins labled ENA DATA CLK in middle section of mini-iso connector:
some 2000 models can be switched from canbus to this 3lb protocol.

Do you have an email address? I want to ask you something :D
ReplyDeleteof corse I have, sorry for moderation, stupid google didn't send my email about pending request to moderate
Deletet.
I do not know, it sould by something with K-line ....
ReplyDeletesorry, I never play with canbus :/
ReplyDeleteHi! I have audi allroad 2001. How can I connect arduino pro mini to my car?
ReplyDeleteI'm affraid, on 2001 models, can-bus is used for this.
ReplyDeleteHi Can give me somebody a simple code for atmega8. I use atmel studio 6.0 I want to send text to the cluster from the atmega not reading of the serial input. Example: I want to read "Audi A3".
ReplyDeletesorry I do not have ane spare free time :( but when got some, i make it for you :)
DeleteI use atmega8 with internal 8MHz. The cluster pins connection is: clock>PD2, data>PD3, enable>PD4. I tried your code changed the connection in it but did not work yet.
ReplyDeleteI testet it on 16MHz version, which are 5V version, arn't 8Mhz versions 3,3V ?
Deleteanyway try new code:
https://github.com/tomaskovacik/arduino/tree/master/VWFIS/FIS_protocol_emulator
Hello. I also tried the new code on Dccduino clone with 12 Mhz quartz but it didn't work on FullFIS from Passat B5 FL. Do you have any ideas why it's not working? Messages from OEM radio works well. Thanks for any reply ;)
Deletetry if radio send same data ("address byte" and crc) as on audi: https://github.com/tomaskovacik/arduino/blob/master/VWFIS/read_cluster/read_cluster.ino
Deleteif yes, then there is a bug in my code :) write is as hobby, so it's posible, patches are welcome :)
ReplyDeletehelp that you need to fix the code that would just write a text without using the serial port

Hi im working on your code, but my FIS is from vw car, the crc check is different can you explain better that operation? CRC=MODULO(SUM(255-DEC),256) thanks!!!
ReplyDeletehttps://en.wikipedia.org/wiki/Modulo_operation
DeleteSUM(255-DEC) is summ of all values in colom 255-DEC
"address" is the same?
What address?
Deleteok then that is correct? 1726modulo256
hi you got to bring text fis vw? I tried the code on your kovo golf4 not what did not work :(
Deletethats bummer, I do not have VW, so I cant help you :( sorry
DeleteHi im working on your code, so my FIS is from VW car, i wrote some messages on the display but the crc check is different from audi FIS, can you explain better that CRC=MODULO(SUM(255-DEC),256)?? there is some messages from VW radio:
ReplyDelete7E ED 0F CE CF CF CF DF DF DF DF DF DF DF DF DF DF DF DF 9E
7E ED 0F AC BE B9 BA DF DF DF DF DF DF DF DF DF DF DF DF 8E
7E ED 0F DF C7 C6 D1 CC B2 B7 A5 B9 B2 CE E3 CE E3 E3 E3 F5
Great job!! thanks!!
first 8bits is something unrelated to text, my guess is address of some kind. I add this to tables
DeleteI think that first 4 bits is other perform data, when this bits are send from radio the ENABLE signal is inactive, then the ENABLE signal is rising up for the rest of the bits.
Deletehow do you do to calculate the crc operation for audi cluster? i tried to calculate crc bits from dumps but is too hard for me. any idea?
I already have an A3´02 cluster and I tried to write in the cluster with your original code but it doesnt work... only bulbs, brake pad, washer fluid advise, maybe the cluster dont show radio message when have this troubles??
ReplyDeleteyear 2002? I think it's can-bus car ...
DeleteMaybe is can bus, but I found electric diagram from ´96 to ´03 A3 8l and only navigation plus use can bus system, all "standar" radios use 3 line ENA/DATA/CLK, maybe is not active in coding of the cluster I try to check that.
Deletehi, what is the can bus pins in the golf 4 dash?? see also this blog, this guy learn you to send data and recieve data on can bus.
ReplyDeletehttp://secuduino.blogspot.com.es/2011/10/fis-seat-leon-cupra-english.html
I conneted to the cluster via atmega 8 usning internal osc. It is working but something wrong. The demo text:
ReplyDeleteString FIS_WRITE_line1="FIS protocol emulator by kovo";
String FIS_WRITE_line2="http://kovo-blog.blogspot.sk";
appear in different character. I changed the two line text and 123456789 is ok, the big letters ABCDEFGH... also works. the problem caused by the small letters abcdefgh.. when I used any small letter different character appear on the FIS. Any idea how can I write small letter what I want to the FIS?
Cluster can not display small characters, i forgot to commit upper case version with strings. Check my youtube videos about know characters by cluster, i made loop wich try to write character with ascii table numbering from zero to 255
DeleteT.
Can we add a modification in the program? If We have to write a small character the program convert it to big one and after that write it to the FIS.
ReplyDeletepatches are welcome ;) also I would like to mentioned, that same characters are on diferent posion then in standard ascii table, for example _
DeleteIf the caracter is bigger than 96 (it is the decimal code of the caracter) have to subtraction 32 from it and the result has to write on the FIS. a=97 A=65 97>96 means 97-32=65 we get A instead of a.
Deletetry what I put on github, but according my test ,but I think it will be litle more complicated just like this ...
DeleteIts ok, the small to big conversion is working, but there some other problem. The first line begin to scroll under 8 character also but the second line is fine I dont know why is it. The other is refres or something I think because the background light of the two line go off for a sec.
DeleteRussian Instruction: https://www.drive2.ru/l/466944997204164856/
ReplyDeletethx! an drive.ru is complex information about VW: http://passatworld.ru/entry.php/1709-MultiMFA?bt=3752#comment3752
Deletelbut this do not works for me :/
Hey, I just wanna know where can I find full schematics of radio you attached to article. BTW great work with reverse engineering those buses, many thanks for your work ;)
ReplyDeleteGoogle: Audi chorus filetype:pdf ;)
DeleteZdravim, podarilo sa ti to rozbehat s nejakym BT modulom aby to zobrazovalo AVRCP meta data (mena songov)?
ReplyDeleteAk ano aky modul si pouzil?
Predom vdaka za odpoved
ahoj, neriesil som to moc, podla wiki podpora by mala byt aj v nalacnejsich cinskych moduloch postavenych na ovc3860 ale z toho co to vie predpokladam, ze jedina vec z 1.4 profilu je "absolut volume"
Deletehttps://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Audio.2FVideo_Remote_Control_Profile_.28AVRCP.29
skusal som aj nejaky csr 86xx blk (4.0) modul ale tam som nerozbehal ovladanie cez UART
Ahoj, měl bych dotaz chtěl bych rozchodit na arduinu s Clustrem Octavia, SuperB Mk1 třídrát 3LB. Nějak jsem nepochopil jestli se vkladají nějaké obvody mezi CLK, DATA, ENA. Díky za informaci.
ReplyDeleteahoj, nemusis to strihat staci zapojit paralelne, ale riskujes tam ze to bude superit s radiom, neviem ako sa to riesi ked je tam navigacia aj ... treba skusit..
DeleteHey, I run your sketch on a Nano, and my MFD is a VW Bus from 99, but I it didn't work. I´ve connected the Pins like in your sketch described.
ReplyDeleteIs there any hint ?
vw need to have different checksum calculation, try change final checksum calculation from mod() to not(), like negation on sum
DeleteThanks for the fast replay, but where is the final checksum calc ? Unfortunately I coulndt find mod().
DeleteRegards
my bad, sorry:
Deleteremove 0xFF^ on all lines where CRC is calculated, for example: uint8_t FIS_WRITE_CRC=(0xFF^FIS_WRITE_START);
change this FIS_WRITE_sendByte(FIS_WRITE_CRC%0x100);
to this: FIS_WRITE_sendByte(NOT(FIS_WRITE_CRC));
try it
I get the Error " NOT was not declared"
DeleteSorry, no luck. I got the error " NOT was not declared
DeleteUps sorry, arduino not() function is ~ so:
Delete...sendbyte(~FIS_WRITE_CRC)
Unfortunately no luck again
ReplyDeletehere is my changed code https://www.dropbox.com/sh/p9dtygw4gueectn/AAAOhmI_3VEPxC1E-ulyppHPa?dl=0
I also changed the I/O ports to the PWM ones on the Nano
Check cluster coding if it is not coded for nvigation....
Deletecheck newest commit at github
DeleteNope, tested on 3 different Arduinos. I´ve tested the 2 lines with vcds and they are fine
DeleteWith the neweset version I event dont get a serial export in the serial monitor
Deleteok, and coding of cluster is ?
ReplyDeletehttp://www.ross-tech.com/vag-com/cars/vwmkIV.html
17-Instruments: K1 -- KWP-1281
Look at the first two digits in the coding. Add the values for the options together to get the correct coding.
00 - No available equipment
+01 - Brakepad wear sensor warning active
+02 - Seatbelt warning active
+04 - Washer fluid level warning active
+08 = Seatbelt Warning active (NAR only)
+10 = Seatbelt Warning Driver & Passenger active (NAR only)
+16 = Secondary Display (Radio/Navigation) active
Yes my coding of the cluster is 21xxxx
ReplyDelete16 for the display +1 for the brakepads and +4 for the washer fluid.
what kind of arduino do you use ? UNO ?
so thats the problem probably, on audi at least for this type of communication (radio only, no navi) cluster must be coded without 16 try it please if you can. at least just to be sure, I use all kind of arduino, clones original it work on all
ReplyDeleteok, I change it agat try it out please ;) (last commit on github)
DeleteI am on vacation so give me few hours to responce ;)
look at this: https://github.com/fismaker/fis
DeleteSo, now I also on vacation and I have time to try again. I´ll give you a little feedback later
Deleteof corse you can, i'm on vacation so for now just link: http://www.audizine.com/forum/showthread.php/405961-Understanding-differences-between-Audi-A4-clusters-and-the-compatibility-issues you need to ground problematic parts like abs, brake pads wear sensors etc ... for fuel you need to put resistor between pin and ground, value must be search online ... (audi a4 b5 its 47ohm, a6 470ohms...)
ReplyDeleteHello, I just wanna know where would i be able to discover full schematics of radio you connected to article. BTW incredible work with figuring out those transports, much obliged for your work..!
ReplyDeletejust google, "schematics audi concert filetype:pdf"
Deletethx :)
Hi, you mention to use pull up resistor. Can you provide a schematic how to connect the Arduino to radio (with resistors) and the LCD display. I have an even older GAMMA BOSE with 3 line protocol. Would like to try if that works too...
ReplyDeletehello :) That is can 2,0.... in Golf 4(Fabia 1FL,2NFL etc....) is can 1,6. Do you have some tutorials with can ID prom can 1,6 ? :) THX KubiCzech
ReplyDeleteGood afternoon.
ReplyDeleteExcuse me, please.
I want to connect a 16x2 screen using arduino to the VW Gamma5 radio.
But downloading your sketch to arduino, the device does not display information.
I ask for help.
Can I have a more detailed description of how you connected the arduino to the radio?
Thank.

there is nothing special about connections:
Deleteclk to arduino pin 3
data to arduino pin 11
enable to arduino pin 2
put pull down resistor(4k7 - 10k) on enable line
and of course, car ground to arduino gnd
12v to arduino Vin
but 1st check if you LCD is working without my code.
Hi! Great project :)
ReplyDeleteDon't you now, will it work with the older models? Like an Audi V8 or Audi 200 20v? It is about 1990-1993 manufacture years. There is a smaller display than in your A4 1999m.y, with animated pictures with errors.
do you have original radio sticker from that era? but 1996 a4 cluster works for sure :)
DeleteI have radio from the next generation with the same pins: CLOCK, DATA, ENA. And as far as I know the original radio has the same pins.
Deletehttps://old.pinouts.ru/Car-Stereo-Audi/audi_gamma_cc_auz.shtml
so it has enabel/data/clk in midle of mini-iso so it should works
DeleteThanks for your fast answer.
DeleteWhat interest me more is that the dashboard cluster can display information not only default pictograms but custom text :)
The dashboard looks like that:
https://www.drive2.ru/l/506320982495985976/
that one probably did not support it
DeleteThx again. Have a good weekend
