The items to use:

Besides one of the workable USB K+CAN cables listed later, you will need the following items:

  1. Arduino Uno (R3, doesn’t matter) or other model Arduino – $3.65
  2. Dupont or Arduino jumper wires (male to female) – $1.33 for 40
  3. 2.54mm breakout pins (6 pins total) – $1.13
  4. Soldering iron/solder (if flashing a generic USB cable with switch that has empty ISP pinouts)

The software to download first:

Not need to install the software,very easy to use! Just copy the software to your PC from CD. All the function on software is activated ready, and can directly to use it. No need to pay extra fee to open the software anthorization. INPA K+DCAN for BMW - $18.99 INPA k+DCAN with Switch for BMW - $19.99.

you will need two programs and the newest firmware file to flash the required software to the Arduino and cable.

Software:

 ARDUINO IDE: https://www.arduino.cc/en/main/software

 AVRDUDESS: http://blog.zakkemble.net/avrdudess-a-gui-for-avrdude/

Firmware:

Newest Ediabaslib Binary cable Firmware:

Credits to Ulrich Holeschak who developed this firmware and documented

the procedure for use with his open source Ediabaslib.

Enhanced firmware advantages:

  1. Can flash the following BMW ECUs without corruption:

 M3/M5/M6 DME (MSS6X)

 E6x M5/M6 SMG (GDSMG3)

 E9x GM Auto (GM1912)

  1. And more…
Bmw Inpa K Dcan Software

 Faster CAN communication (block size 0 and no separation time).

 Allows configuration of CAN mode all the time, not only after power on.

 Allows configuration of the CAN parameters (block size and separation time)

 Correctly displays the ignition status (only available for K-line mode).

 Contains a bootstrap loader that allows firmware update without opening the device.

 Reduced power consumption due to use of sleep mode.

Workable cables:

We tested 2 kinds of Inpa K+CAN cable based on ATMega162 board can be flashed with this updated firmware, we are not responsible for any other cables that are not listed below.

  1. ONESTOP Cable with ISP header: No soldering required
  1. Generic AtMega162 based USB INPA cable with switch and ISP headers on circuit board: Soldering of header pins required

Before ordering INPA USB cable, Verify with the seller that the cable does have the ISP pin

header.

Look at the images below, the circuit board with pin header that we have already soldered on. The stock cable will not include the male pin headers, but rather empty holes which will allow you to solder on your own pins.

How to install the software for Inpa K+CAN cable?

STEP 1: Install software programs and download latest firmware

After downloading the files listed earlier in this document, install all of them using the default options.

Notes:

Arduino IDE:

When the Arduino IDE asks if you want to install any drivers from ADAfruit industries, select yes

or OK. It will prompt multiple times, but continue to agree to the driver installations.

AVRDUDESS:

Allow AVRDudess to put an icon on your desktop

Binary firmware:

Extract file with your favorite .zip archive extracting utility and save it to a folder on your

desktop.

Configuring the Arduino

STEP 2: Connect the Arduino to PC using supplied USB cable

  1. After installing the software above, plug in your Arduino to the computer using the supplied USB cable.

Windows will detect and install the driver for the device.

Good to know:

if it does not and it shows that windows has failed to install a driver, download and

install the driver from the following link (CH341 based Arduino boards):

  1. Verify the com port of the Arduino:
  2. Open up windows device manager and expand the ports tree to view the Arduino com

port designation (COM5). Make note of this for the next step.

STEP 3: Flash Arduino as programmer

  1. Run the Arduino IDE application and click OK to any prompts that show (java/firewall).
  2. Click the TOOLS menu > BOARD > and select the Arduino board you have (be it Arduino Uno,

mega, etc).

  1. Click the TOOLS menu > PORT > and select the COM port you made note of in the previous step (In this example its COM5).

Next, click on the FILE menu > Examples > 11.ArduinoISP >ArduinoISP

It will open up a new IDE window containing the code which we will upload to the Arduino.

Finally, Click the Arrow button (next to the checkmark circle) highlighted (in white) in the image below.

Clicking the Upload button will then begin to compile the sketch, and when done will tell you it is “Done uploading”.

You may now close the Arduino IDE. The Arduino is now an Atmel programmer!

Connecting the Arduino to The Inpa K+Can Cable ISP Pin Header

Connect Arduino to USB cable using jumper cables

For this step you will reference the images in this document and table below to see the correct pinout designations for the type of cable you are trying to flash. It’s imperative you connect the correct pins on the Arduino to the correct pins on the cable you are trying to flash. Failure to do so will prevent the flash from completing successfully. Bear in mind it makes no difference the color of the wires, as long as the pin number on the Arduino matches the Pin designation on the ISP header on the USB cable you are trying to flash.

STEP 5: Flash cable with enhanced firmware

Verify:

  1. The Arduino and USB cable are correctly connected together via jumper cables
  2. The Arduino is connected to the computer by USB cable

*Optional: Plug the USB cable into the computer to supply it with power (it isn’t necessary to

install any drivers for it).

Once the above has been verified, run the AVRDUDESS application and configure the options exactly as

shown below:

Programmer (-c): Atmel AVR ISP

Port (-P): COM PORT YOU NOTED ABOVE (COM 5 in this example)

Baud rate (-b): 19200

Bit clock (-B): blank

Presets: Default

Options: Uncheck all (none selected)

Fuses lock bits:

L : 0xFD

H : 0xDC

E : 0xF9

Set Fuses: CHECKED

LB: BLANK

Once the AVRDUDESS options have been set:

  1. Click the detect button at the top right corner to verify the Arduino can communicate with the

USB Cable microcontroller. If everything is connected properly, it should detect and specify the

chip in the terminal window and populate the MCU (-p) options with the correct

Bmw Inpa K Dcan Software Free

microcontroller.

If AVRDUDESS cannot detect the correct chip, verify the Arduino to ISP header connections and

double check soldering points.

  1. Next, set the cable fuses by clicking the WRITE button directly under the ‘Fuses Lock Bits’

heading. This will write the three fuses we specified earlier to the cable. AVRDUDESS will also

display a terminal message verifying the fuses as shown below.

  1. Next, under the FLASH section of AVRDUDESS, click the ‘…’ next to the empty space to browse

and select the ‘Combined.hex’ firmware file located in the CanAdapter folder from the archive

you extracted from the latest binary file located at

  1. Verify that the Write radio button is selected, and Auto (writing only) is selected from the

Format drop down selection.

  1. Click ‘Go’ to begin the flashing process.

At the end of the flash, the LED may light up on the USB cable.

That’s all.

Your Inpa K+CAN Cable is new upgraded with enhanced firmware.
