shubhang, u are always welcome to post what help u require ( with the specifics) here itself on the forum. Doing that would help other people who may be having similar queries on the project. :-)

what is it that ur code is doing?? u are not reading the TH/TL values anywhere. the logical flow in the external interrupt routine should be as follows: 1. read the TH0/TL0 values and store them in som...

u r right about the voltage levels . sorry about the error on my part. and yes, u can use any op-amp as a comparator as long as it can handle the frequency of the input signal. if ur input frequency (...

no, the question is not silly but perfectly valid :-). actually, apart from the standard character set, the table also contains some special key scan cods like the function keys F0-F10 on the keyboard...

as u mentioned the output fluctuates between 2.2V and 2.6V. So keep the reference voltage on the other arm of the comparator between 2.6V and 4.0V if u want a high logic on idle state OR keep it anywh...

i think u need to use a comparator prior to giving the signal to the uC solely because the voltage on idle state is 2.8V which is not a purely digital level for the uC.

if it is a 'c' program, hope u have selected the right device before creating the project. To cross check, go to Project -> configuration otions -> general where u will find the device selected. Also c...

It would be much better if u also download the AVRstudio for a suitable IDE.It will automatically integrate with the installed winAVR. Will save u the trouble of manually creating makefiles and compil...
