Power Supply Question
If it has a 2A fuse shouldn't it be able to supply at least 1A? (with a 50% design margin)

temp sensor I2C + USART bug
Here is some sample working code with printf that I use regularly: #define USART_BAUDRATE 9600 #define BAUD_PRESCALE (((8000000/ (USART_BAUDRATE * 16UL))) - 1) //value to load...

Xmega ADC limitation
I want to use the ADC up to 22 kHz (so I need at least 55ksps). Currently I am using Atmega168 which is nowhere close to that (with it's 200 ksps limitation). I wonder if they...

Hi guy's....just check this....?
Quote: so it's always less than 5 True, but if you add an i++ in the while loop value of y will change.

Baud rate and ADC sampling frequency
Thanks again, Cliff. Ok I ran the raw data with the C code and attached is the waveform I got (for one cycle). Here is some thinking out loud calculations: I have 28 samples/...

Baud rate and ADC sampling frequency
Sorry about that,Cliff. Yes you are right, I did use a ASCII to decimal conversion website to post process the data.Attached is the raw data captured from the hyperterminal. This...

Baud rate and ADC sampling frequency
Thanks Bob and Cliff. I tried to send raw data to my hyperterminal and converted it from ASCII to decimal. I am using 7.3728MHz, 115200 baud and capturing a 10KHz sine wave....

Baud rate and ADC sampling frequency
Thanks for the idea, Cliff. All I need is to transmit 9 bits/sample. (my values are...

Please criticise my schematic
I always tend to use a push button switch from the Reset pin to GND with a cap to GND as well. This way you can reset your uC if needed. Of course you may need debouncing for this...
