-resolved- Compiling with AVRStudio

[borisdekat]

Hi, I think it is something very obvious but I can't get it to work...

Trying to compile HID_mouse example with AVRSTUDIO.

Did copy all the USBDRVto the project directory, changed usbconfig-protoype.h to usbconfig.h, did make some adjustments for the correct port and CPU speed.

Added to the project the source files: main.c, oddebug.c, usbdrv.c and usbdrvasm.S

When I build all: I get -only- the warning:

../main.c:155: warning: implicit declaration of function 'usbInterruptIsReady'
../main.c:159: warning: implicit declaration of function 'usbSetInterrupt'

and later -only- on the error:

D:\sw_atmel\attiny44\default/../main.c:155: undefined reference to `usbInterruptIsReady'
D:\sw_atmel\attiny44\default/../main.c:159: undefined reference to `usbSetInterrupt'

Seems I am missing some link ?

Any hints ?

Thanks,

Boris

Actually, at first i also got stuck when trying it with AVRStudio...
But, after seeking up some reference i got the sample which is using avr studio for IDE.
You can look avr-cdc example for Your reference.. I got my project compile with it makefile..

Here i try to post my working makefile...

I can attach the working mouse example projects here if you want, but i didnt know how to attach file in this forum..
If it is allowed, i'll upload the file to shared file hosting and post the link directly here...

I found my Error !. Nothing to do with AVRstudio and/or linking stuff.

I used for the hid-mouse example not the included usbconfig.h but started of with usbconfig-prototype and made the (I thought...) needed changes. Apparantly I missed one very important one:

#define USB_CFG_HAVE_INTRIN_ENDPOINT 0
/* Define this to 1 if you want to compile a version with two endpoints: The
* default control endpoint 0 and an interrupt-in endpoint (any other endpoint
* number).
*/

It should be "1" to enable the interrupt routines in main.c to function correct (even compile correct)....

So a real newbee error

Thanks for the reply , gl
