[En-Nut-Discussion] How to: Use a interrupt controled counter on an input port

[Andreas Witsch]

Hi Community,

I'm a rookie with the ethernut board, but i have to count the time how long a '1' was set as input.
I expect it in a range of 1 to 10 ms.

I tried it to use polling on a timmer with the timer example from the ethernut dok (http://www.ethernut.de/en/documents/at91-timer-irq.html), but i got some Problems with the include files.
My AVR Studio abort the compile process with 4 Errors:

"c:/WinAVR/bin/../lib/gcc/avr/3.4.3/../../../../avr/include/avr/eeprom.h: error: previous declaration of 'eeprom_read_word' was here
C:/ethernut-4.0.1/nut/include/dev/mweeprom.h: error: conflicting types for 'eeprom_read_word'"

I think i have a problem with the include direktory's but i can't localize it.

In addition i have an Error:
"../iotest.c: error: `sig_TC1' undeclared (first use in this function)"
(compare to the Examplecode)

It would be nice if i'd got a good idea to solv both problems ;)

thx & best regards Andreas Witsch
