Odd problem with printf and uart
Yes, Cliff it is GCC. I do have the FDEV_SETUP_STREAM defined. I will post all the code.

Fast timer operation
Yes, I did read it briefly after it was mentioned on my post. I will read in detail to see if this will work for my app.

Fast timer operation
Quote: Byte-by-byte transfer, and no inter-byte gaps? I wish :). No, I do have the inter-byte gap between bytes.

Fast timer operation
That is exactly what I was going to add. Anyway, I got it to work at 4MHz. For now I think I am ok with the burst of bytes. Just out of curiosity is bit banging the only other...

Fast timer operation
But I seem to be going from 8MHz to about 1 MHz (even Khz) Is there a faster way of doing this so I can get the spiclk at 4MHz using a divide by 2 prescalar for a clock of 8MHz?...

Fast timer operation
Ok I tried using the SPI to generate a clock at 4MHz and could not get it. I am using only Master configuration and checking the Sck and the MOSI pins. Following is my code: #...

Fast timer operation
I am trying to create a given timing waveform with the help of an AVR (something similar to say controlling an LCD). To do this, I am trying to use bit banging of the AVR ports....

Fast timer operation
Thanks, Lee and Steve. I will try the timer CTC mode with a compare match of 0. By controllable, I mean I would like to set a flag when the timer has finished counting so that I...

Opinion on design idea (loading patterns from AVR to DUT)
One more question: I really need to program the DUT through an AVR SPI connection. Do I really need to store the patterns in the AVR EEPROM? Would it make more sense to store...

Opinion on design idea (loading patterns from AVR to DUT)
Sorry about the acronyms. You are correct about DUT, INL and DNL. I am trying to use the AVR as a "programmer" for another device to load a pattern in and put the other device...

Commonly used high speed 16 bit ADC IC's
I am trying to design a general system that will work for almost any type of input signal like signals from different sensors and also work as a general purpose spectrum analyzer.

Commonly used high speed 16 bit ADC IC's
Thank, gchapman and ignoramus. The cirrus logic ADC looks really good for the price. I may have to use the FTDI to clock in the samples. I wonder if I can push an external ADC...
