I am new to this list, and new to the AVR processors, but not new to imbedded computers. I will be using an AtMega128 in a project and want to use the SPI to drive a quad D/A converter (the MAX537) and a couple of DDS chip (the AD9834). I want to use PB 6 and 7 to do the selectin

If you are not a programmer, especially not an embedded programmer then the answer is plain in my opinion: Bascom AVR. But really, what is your goal? Where are you going with this? DLC M F wrote: > Hi friendsi am new in AVR's.i want to srart learing this powerful chip.besides ido
