AD9102 Output Signal

Hello Larry,

Thanks for getting back to me so fast.

The simplest waveform I want to generate is a swept square wave.

So Ram [0] = 0x7FFF  (-ve min)

      Ram [1] = 0x8000  (+ve max)

Start = 0, Stop =1, Pattern length = 2

Output directly from Ram, continuous pattern, Address counter incremented by DDS_MSB

Set DDS frequency to any value (I used 1000 Hz).

I expect  a Square Wave of 500 Hz.

If this can be done, I'll be grateful!

regards

Bart
