The previous link is for C compiler, for assembler use the link:

Download both files and install them. If you want to use C in AVRStudio, instal WinAVR first.

Hi,
As far as I can see from datasheets you can replace 2 74hc595s and 2 ULN2803 by one STP16C596. There are two differences:
1. ULN2803 has greater current sink capability (500 vs. 120 mA)
2. STP16C596 has courent sources so that you don't need resistors in series with...
You must use an external oscillator. Adding the crystal alone will not help you.
You have two possibilities:
1. Make a simple oscillator using 555. Frequency is not so important but try with 1 MHz
2. If you have another board with microcontroller use its clock as the source. Connect clock output...
Re: Low Pass Filter Design
You have probably made a mistake in the values of capacitor or resistor, since you get 10 times lower result.
How do you measure your LPF response?
