Support Forum
Thanks to an enterprising member we have a support forum:
Please join and use for all your questions, suggestions and discussions regarding the er9x/eepe platform.

eePe and er9x are free to use under the GNU v2.0 License. Feel free to use, copy and modify it as you wish!
I have spent a lot of time (and will continue to) to make this software as good as possible. If you feel that this software has been beneficial to you please show your support by donating. This will be greatly appreciated and you'll be added to the "contributors" list in the code (optional of-course).

  1. Download the current er9x.hex file from
  2. If you have the SmartieParts 9x Programmer board, then plug your radio into the usb. The power switch does not need to be on. If you're using a different programmer then make sure you've connected it to your radio according to its instructions.
  3. Open eePe.
  4. Verify the programmer settings are correct:
    • Go to Burn -> Configure.
    • Set the programmer name, port and the relevant arguments.
  5. Select Burn -> Write flash memory:
    • Select the er9x.hex file you downloaded.
    • Select ok and wait while the radio is programmed.
  6. After the flash write a message about the eeprom being wrong will appear on the transmitter screen. Press a button and wait until the FW formats the EEPROM.
  7. Follow the directions to calibrate your sticks. They are found on the er9x home page. Look for the section titled Calibration. Er9x home page

Programmers and Drivers

USBBASP Win 7 and Vista Drivers (For Smartieparts and Protostack)

Fixes in Linux/Ubuntu

To run properly you need to enable AVRDUDE to run without being root.

Plug in the programmer and run

lsusb | grep libusb

You should get a line like this:

Bus 003 Device 002: ID 16c0:05dc VOTI shared ID for use with libusb

Notice the two numbers after ID.

Create a file called 10-usbasp.rules in directory /etc/udev/rules.d

 SUBSYSTEM=="usb", ATTR{idVendor}=="XXXX", ATTR{idProduct}=="YYYY", GROUP="adm", MODE="0666"

replace XXXX and YYYY with the numbers from before. (ID XXXX:YYYY)

Then execute:

 sudo restart udev

Alternatively just run this line:

sudo echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="16c0", ATTR{idProduct}=="05dc", GROUP="adm", MODE="0666"' > /etc/udev/rules.d/10-usbasp.rules

Translation Instruction

To help with localization you need to download Qt Linguist from here:

After that, download the eepe.ts file from here:

If you're more at home with a ".po" file you can download this one:

Rename it to eepe.XX.ts where XX are the letters of your locale.
Edit the file with Qt Linguist.

After you are done, send me the result and I'll add it to eePe.

Linux Build Instructions

(by ghosthb)

  1. Open a command window and type 'sudo apt-get update'. To update your package lists.
  2. Next type 'sudo apt-get install subversion build-essential libqt4-dev libqt4-network'. Select yes when it asks. This makes sure you have all of the tools and packages that are required.
  3. Download the source. This command will create a folder in the directory where it is run from, so switch directories if you want it in a particular place. 'svn checkout eepe-read-only'
  4. Change into the source directory. 'cd eepe-read-only/src/'
  5. Now build the program. 'qmake && make' -this might take a while
  6. The compiled program is now in this directory. Either browse to is and double-click or from the command line here './eepe'
  7. To install the program you need to run "make install" as super use. Under Ubuntu this is "sudo make install".

Latest: svn checkout eepe
Stable: svn checkout eepe -r 233

MAC Instructions

This instructions was taken from the Gruvin9x page (Thanks Groot!)

Mac users can install the Qt Developer stuff from here:

Then svn checkout eePe from the eePe project site.

svn checkout eepe

Under Windows and Linux, you build the eePe application like so ..

cd eePe/src

But on the the Mac, when you run qmake, which would 'normally' create a Makefile for the build process, a Makefile is not created. Instead, and arguably even better, qmake creates an entire Xcode project structure in a directory named eepe.xcodeproj/. To build the program, open the project in Xcode, click Build and Run and you'll be all set!

Next you need AVRDUDE on your mac if not already there. to test just type in a terminal avrdude and see.

If you don't have it, I'll suggest OSX-AVR (Google)

In eePe, you have to add the AVRDUDE location (burn => configure) add this for avrdude location:



Simulates ER9x Tx

You can "test drive" the er9x FW without even having a tx.
Program your models and try them out on your computer.

Edit all EEPROM values

Upload/Download both flash files and eeprom files to Tx via AVRDUDE

Drag and Drop models between different memories

Share setups and models easily.
