Hi guys,
I am trying to migrate to AvrStudio5... but it is not simple and not so many examples, so I know I have to come to you.
I used the following code in avrstudio4 + winavr, but now not valid anymore.
Could you please help with the new statement to utilize?
Thanks
// USART interrupt call
ISR(USARTD0_RXC_vect){
...
}
// Pin interrupt call
ISR(PORTD_INT0_vect){
...
}
// Timer interrupt call
ISR(TCF0_OVF_vect){
...
}

Koshchi Which AVR model?
ArnoldB Quote:Likely an xmega since those don't look like vector names of any regular mega or tiny.Which AVR model?
Koshchi that great productivity enhancer, called AVR Studio 5

any error messages to quote, perhaps?
Which AVR model?
Yes, it is XMega128A1, and message is:
Quote:
Error 2 expected declaration specifiers before 'ISR' C:\xmega1-avr5\test_xmega1\core.c 111 1 test
And actually (may be beta), there is this other error :shock: :
const uint8_t test_rev[TEST_LEN]="TEST1";With the following error:
Quote:
Error 1 parameter 'test_rev' is initialized C:\xmega1-avr5\test_xmega1\core.c 35 1 test
Thanks for your help

Do you get errors on all your ISRs in that file - there seems to be some fundamental problem with ISRs. Did you
#include
?

bmarcello Thanks for ur reply,
Actually I had but commented
#include
Now without comments I have the following errors/warnings for each time ISR is called:
ISR(USARTD0_TXC_vect){
Error 1 parameter 'test_rev' is initialized C:\xmega1-avr5\test_xmega1\core.c 35 1 testWarning 2 'signal' attribute only applies to functions C:\xmega1-avr5\test_xmega1\core.c 111 1 test

Warning 4 'externally_visible' attribute ignored C:\xmega1-avr5\test_xmega1\core.c 111 1 test
Error 5 expected '=', ',', ';', 'asm' or '__attribute__' before '{' token C:\xmega1-avr5\test_xmega1\core.c 111 22 test
Note: This code is fully functioning with AVRStudio4!
Thanks for your help

bmarcello Same fw with AVRStudio4 works well with ISR routine (or macros).
Please, let me know what do I need to use with AVRStudio5...
Thanks
JohanEkdahl Again: Show more code. At least the complete ISR.
And Steve's question is quite relevant: Are you explicitly calling ISRs? And furthermore the message you quote hints at you calling them with parameters passed. If so, this makes no sense.
In short: ISRs are not to be called explicitly. ISRs are functions servicing interrupts, i.e. they are called asynchronously by a hardware mechanism. If you need something executed both as a consequence of an interrupt condition and explicitly called by the code then break that something out and call it both from the ISR and from other places where you need it to execute.
This might lead to other problems though. If your interrupt timing is critical then this approach might break it.
A redesign might be necessary. Alas, there is little advice that can be given with the amount of information you have presented. Specifically, there is no clear and simple answer to "what you must do to make it work" unless we get more of the picture.
Lastly: Just because the code worked with a previous version of the compiler, that does not necessarily mean that the current compiler will swallow it whole. As long as the compiler implementers follow the rulings of the language standard (in this case the C language) they are free to change behavior.
bmarcello Hey, it's weird!
I simplified the code to post here... same issue.
Then I just cut and paste the c and h file, copied in another folder... compiled before posting... it works!
I re-checked and if I import the prj from avrstudio5 (import project...) compiler mess-up.
Sorry for wasting time, but that is weird...
Thanks
