Baud rate and ADC sampling frequency
Thanks, Jim. I will try point 1). I may have an offset on the signal. @JC thanks for the AVRCalc idea. I used Kevin Rosenberg's tool and found that the error for an 8MHz crystal...

Baud rate and ADC sampling frequency
I agree that my main limitation is the UART but I need to display the real time data on my PC. @Cliff, I will change my logic so it is ADC interrupt driven. I agree it does not...

Baud rate and ADC sampling frequency
Thanks for the feedback, guys. First of all I had a typo in my first post. I am using an M168 not M128. JC, Steve is correct, I will need an UBRR of 51. Quote: at no time are you...

Best way to choose which program to load into AVR?
Thanks for your feedback, guys. @ReAlAl: Why would I need a timer? Can I not use the pin level change interrupts for this purpose? Shouldn't there be a while(1) loop after the...

Best way to choose which program to load into AVR?
Thanks, Steve and MBedder. @Steve, So how can I do it? Should I load three different hex files into my AVR? Any pointers/links would be very useful. I have never done this before...

How to program the chip
Having tried multiple programmers (AVRISP, JTAG) I vote for the STK500. I use that even when I am prototyping on my breadboard.

Looking for heating coil
Thanks for the pointers, Tim. That link says it is out of stock but I will keep checking. @peret: That makes sense, I did not take the latent heat into account. I am going to...

Seeing crystall waveform with oscilloscope!
Is the waveform clean and stable on the scope? In other words, is it triggered correctly on the scope? If you see a "jitter" in the waveform on the scope, it may not be triggered...

Looking for heating coil
Thanks, John and alwelch. I had seen that beverage heater earlier on amazon. I will certainly consider these options. I will have to modify the peltier trick to make it...

Looking for heating coil
The end use is for heating oil. The oil frequently gets frozen in winter and I need it as a liquid to get it out of the bottle. Of course I have other simpler options like...
