beginner questions...

hi, i*m very very new to programming microcontrollers.
can someone tell me how i can "read" inputs on a atmega8?

at PD2 there is a sinus-curve (0-5V) betwen 40hz an 1000hz. and i want to write a litle program, that calculates the frequency.

how would be the code when i want, that an LED (at PD4) swiches on everytime, when there were 10000 "highs" and swiches off for the next 10000 "lows" at PD2 and then again and again...

is it possible to get a signal high or low with "if portd.2 = 0" or "if portd.2 = 1"???

please help.

(sorry that my english is sooo bad...)

aahh!

i know why this was not working.... ....i wanted to read PD2 with portd.2 but this should be pind.2.....

hey again,

i need help.
i want to work with frequences. and i found a realy nice source code for this. but it is not for AVR chips. its for PIC.

could someone be sooo nice, and translate this for me? i want to use an atmega8....

i dont need to have this on an lcd. a variable whith the frequency is enough.

here is the code: http://tinyurl.com/yq3d3b (in the second post)


THANKS A LOT!!!!

Hallo Hannes,
ist ja beruhigend, dass ich hier nicht der einzigste deutsche bin,
der mit mikropascal arbeitet.

Aber die Arbeit dass zu übersetzen, musst du dir wohl selber machen.
