Commonly used high speed 16 bit ADC IC's
Thanks, alwelch for the link. That board does look interesting but expensive. Will consider using it. Just curious, has anybody implemented the FFT in an FPGA? That would also be...

Commonly used high speed 16 bit ADC IC's
Application is sort of like a spectrum analyzer to capture and analyze signals. Right now I am trying to determine what would be my limitations of input frequencies and levels....

Commonly used high speed 16 bit ADC IC's
Good point Jim. I was thinking of storing the captured samples in RAM so it won't be real time. Of course I run into the problem of the RAM filling up but I can synchronize the...

ADC and internal RAM
Ok it worked. I was using ADCSRA |= (1 << ADEN); instead of ADCSRA &= ~(1 << ADEN);

ADC and internal RAM
Hmm I did indent my code and used the preview and it looked good. I tried the code you mentioned.My main looks like this: int main (void) { DDRC = 0x0F;...

Zigbit module newbie help
Thanks,alexru. I checked for the Zigbit development kit and it is > $300 a bit too expensive for my budget. Right now I am just looking for the minimum configuration to get the...

ATmega 128 development board Issue
Looks like JTAGEN fuse is set. Maybe disabling JTAG will help?

AMAZING temperature range Mega168
It would be interesting to see how the internal oscillator performs at those temps. I have seen internal clock generators which have logic gates stop functioning due to the timing...

FFT basic question
So for example if I had 256 samples of a signal with sampling frequency of say 10 ksps, my lowest frequency would be about 39 Hz? (10000/256)
