These are the settings I would use m So you are indeed using PD7 as the jumper? That pin must be an input and held low for the bootloader to activate. Make sure you are compiling for the right chip, and make sure the address of the bootloader is set correctly in the makefile, for the atmega162 this ...

I don't use Eclipse, but it sounds like it's a defect with the plugin
so... I'd personally suggest use something else for compiling the project
give this a shot? http://code.google.com/p/avr-project-ide/

did you reconfigure the bootloaderCondition() ? you didn't mention it in your post

excellent, although calibration might get a little annoying when you try making multiple devices, thanks for the information.

the way you write numbers was a little confusing at first, then i remembered some countries use commas for decimals, where are you from?

unable to enumerate usually means a bad config or hardware issues, assuming your initialization sequence is correct (interrupts enabled, watchdog disabled or taken care of, etc) if you really are seeing multiple packets being sent, then I suspect you have a bad config, so double check everything, es...

if you are new to C, you need to get familiar with "make", "makefiles" and compiling C projects in general. That command is meant to be typed into the command line or console. To use AVR Studio with V-USB, only add usbdrv.c and usbdrvasm.S into the project, not the other stuff yo...

you want to use usbFunctionWrite, not usbFunctionRead use usbFunctionSetup to determine whether or not you need to read data from the computer, if so, make sure usbFunctionSetup return USB_NO_MSG then just write your usbFunctionWrite to handle the data, it provides the data in an array and tells you...

Are you using 64 bit? There is a problem with 64 bit drivers not working if they are not signed. I know a joy stick is HID and thus should not require a driver though. I run both 32 bit and 64 bit Win7 and I've been able to build HID joysticks, mice, and keyboards for both, although my 64 bit machin...

i need exactly 360 possible values, its gonna be a flight simulation device, and a circle has 360 degrees does the encoder have exactly 360 discrete values? if not, then i suggest you either use the number of discrete values per full rotation of the encoder, or stick with 256, or maybe 65536, and t...

359? uh, i'd suggest you avoid that, stick to 0-255 and use software to multiply the number by 1.40784314

I'm pretty sure either you can make your device a HID keyboard with additional application keys, or write a background process as a "driver" and make it launch programs.

two solutions: make your host application event driven (I can't help much with this) or elongate the period which your button appears pressed, using a hardware timer or loop counter int pressedFor; // counter while (1) { usbPoll(); if (buttonIsPressed()) { pressedFor = 0; // reset counter } if (pres...

com ports above 4 can't be simply written as com4

you need to write

//./COM10

try it

Oh yea the provided LibUsbDotNet examples are great, just use the device finder to create the device and call the methods available on the device to communicate, like "ControlTransfer" for stuff you want to send to usbFunctionSetup to handle, really simple.

If you are totally new to this, how about trying something less advanced than dealing with Mingw and makefiles and such? Go get Visual Studio (the express editions are free) and then use LibUsbDotNet (download it, install it, and in your Visual Studio project, "Add Reference" to the libusb...
