OK. but where can I find contact to Christian???

I'm look if have free pin on PORT D , no don't have free pin, I have 100pcs board , I can't cut and add new wire. no , I can use only firmware with this pin D- Port C - 0 and D+ port D - 2 , really we need D- and D+ in same port , or just definition is for both pin, I don't see in to deep of V-USB p...

ehm sorry but ...
I have complete PCB board of my old project , there is no possible to cut wire and change to other.
if I only draw new board , then no problem, but I want use V-USB in existing project where is used AVR-USB project from Igor Cesko .

any suggestion .

regards

Hi.
I use board with firmware Igor Cesko, and he make firware full on ASM and use two pin and It does not matter what port pin use only D+ must be connect to INT0 .
Now I want use firmware V-USB and D- is in port C.
realy I can't use V-USB firmware???

regards

Hi.
May be I'm not good understand documentation but.
I have D- connected to PORTC 0
D+ connected to PORTD 2
if I define
then D+ use INT0 but other use too into PORT C.
there is not possible to define different port pin???

regards

Yes , but in this file is Port setting for both pin D+ and for D- .
I don't know where define PORTC for D- pin.

Hi all.
I have old PCB board where I used firmware (all asm) from Igor Cesko. But now I want use with V-USB.
D- is used in PORTC pin 0 , and D+ is used standard PORTD pin 2 (int0).
I'm search where I need make change for using my port setting but don't know find it .
can any help with this???

regards

Hi.
If you want only connect device to USB and PC detect Serial port and then standard read write to serial port use http://www.recursion.jp/avrcdc/cdc-232.html but need install drivers in to WinXP with SP3.
then on function UartPool can add own function .

Hi.
I read your post and it's very interesting.
Is possible to make low size byte project and post in this web???
if you can then optimize to minimum code size , there are more people who want it.

Hi. there is more way how to do it. How I use this : on first MCU start at bootloader mode. and control if is connected to USB or no . if is connect to USB then start normal bootloader if no then jump directly to main application. and if main application detect USB then reset USB and start firmware....

Hi. I have problem how to correct software unplug device from bus. I have HId bootloader and HID device (my self program). If plug device to USB then start bootloader and I can flash new program to MCU. if flash then jump to user program . then start my HID device and can send receive data from to U...

Hi.
I'm finish.
I solve problem . now I have easy HID USB-USART bridge.
I use some function form CDC-USB and from HID-Data

regards

Hi all. I want create easy UART to from USB bridge. only one defined speed I want use . I use easy HID project HID-Data. On one packet can send only 8bytes on one time (7data+1ReportID) I don't need more. if receive data from uart then store it to buffer and control , id data stored size are 7 then ...

Hi all. Today I'm think and find any solution how to check if is USB connected or not. Some user use USB only short time , other time use native function and with interrupt too. If use interrupt (timer, UART ...) than can't use USB . There is big time critical function for emulate USB on AVR MCU.O w...

Again , again.... Sorry for my english but must give this question again. how to detect if MCU is connected to USB or not. Why??? if I want run application but I want know if mcu is connected in to usb or not, if is then use function for usb communication and disable any special function (used inter...
