Problem solved. With those two capacitors removed i flashed once again the uC and wrote the fuse bits and everything works fine. Project done!

well... i managed to 'unlock' the uC. i simply disconnected the ground from those two 22pF capacitors, and probably the XTAL1 took some kind of clock from the crystal , otherwise i cant explain it. then the question is remaining... why 0xC9 and 0x9F does not work for a 12Mhz crystal????

OK . I run the hid mouse When i Checked by AvrOsp my fuse bit high and fuse bit low for external osci I found out that on make file I have a diffrent Copied from below exampale now i use ! : High: 0xD9 Low : 0xFF And it works cool ! well i dont quite understand. you set these fuse bits from above f...

Well I have exact the same problem with switching on one of those exampale ;0 The same info that windows don't recognise the device. We set the fusbit for 16MHz Oscillator and generally that's all :/ And of course change the Config.h cause of difrent bit of portD usage. I'm not really familiar with...

i managed to compile the makefile using mingw, and i got the usb-led-fader.exe. the problem now is that when i plug the device in the usb port, windows shows me a "usb device not recognised" message, and in commandline when i type usb-led-fader status i get this error: "could not find...

I wrote the hex file on the atmega8, and as from the description, i tried to type the command "make" in the directory commandline. it displays the following error: gcc 'libusb-config --cflags' -O -Wall -I../common -c usb-led-fader.c /bin/sh: libusb-config: command not found /bin/sh: gcc: c...

This is not my first MCU project. I know pretty much about LCD, different types of motor interfacing... interrupts, ADC etc. I just wanna know for example if i write a command line in avrdude or something, the uC will execute it immediately. Or V-USB is just some kind of programmer like USBASP? Is i...

Hello. I have some questions related to V-USB. 1. Does V-USB allowing "real time" communication of an uC with the computer via USB? 2.If so, what are the steps for a small application of this type? For example turning on and off a led, using Atmega8? first..should i load the firmware on th...
