Thank You _frank26080115, but this link is for device firmware, I solved my problem of compiling program.

usbdrv.h and http://vusb.wikidot.com/driver-api describes functions

device firmware has nothing to do with libusb

the problem was including files to project, but now it's solved. Another problem is with Host software, which file is describing usb_int() and other functions? I try to include libusb library but i failed. So my question is which file describes all this functions an where i can get it, becouse i failed with Libusb-win32, I just can't find files I need... please help me.
Thank You, Vaidotas.

I have one more question. I was made USBASP programmer, it works nice, computer recognize it, but if i compile hex file using source, it is smaller and does not works. Why it's happening? How to make hex file from source. I'm using AVR Studio 4.
Thank you.

Hello,
I'm begginer with v-usb too. The problems of making hex files of examples, like PowerSwitch, Automator. It's no problem, then project is using ports which isn't in my uC, i just change it or delete ( if it is funkction to do something, like turn on led). The problem is then I' compiling project, every time it shows me that i missing function "usbCrc16Append", ant i don't seen ever how to write this function, so the only thing to do is to make "//" before function in usbdrv.c file. Is there other solution?
I'm using Attiny26 uC with 12Mhz crystal, and i set frequency F_CPU 12000000L. Is is good?

Thank you,
Vaidotas.

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 you mentioned

beginning with VUSB.. need help

2010-08-12T20:18:12+02:00

Hi..
I am just beginning with VUSB.. I downloaded the package from objective development web and gave a try to custom-class example.. In the "Building the firmware" section of readme file (in second para), it is written "Type "make hex" to build main.hex" . I can't understand that where I need to type it. i.e where I need to type "make hex" to build the project...

I also tried to add .C files , .h files,make file and files in usbdrv folder in a AVR studio project .But I got errors.. VUSB wiki documents link is also not working.. Please can anyone make a tutorial for beginners in VUSB.. I have previously made several AVR projects in assembly and codevision AVR but have just gotten stuck here..

I am using windows platform.
