I did set up the pins as required (jumpper 15 and 17 pins 1 and 3 the ) but still cant get anything out..
1)is there suppose to be some input fruquency to which to run the DAC and if so what is the max or min?
2)what i have noticed is that i have to use the pin names as they appear in the datasheet is that correct(i mean the naming)?
3) i have chosen to use DAC_B and FPGA_CLK_B_P..my biggest worry is that even in the signal tap i cant get the analog waveforms and what i heard is that the signal tap should display what is suppose to be displyed on the oscilloscope,if i dont use the DAC will i still see the analog waveforms in the signal tap?
sorry for so many questions but i really have to get this working..i have got a final demo on the 17 nov
kind regards

Hi,
I have the same kit.
DAC:
If you try the example shiped with the kit, it should be work. The issue is may due to the fact that on the hsmc daughter board, there are RF transformer ( "big white cube") near the sma connectors. This transformer have a band pass located between 300kHz and 300Mhz. So the dc and lower frequencies are cut.
Signal tap: I didn't use but I remember with the development kit there is a quick start guide which tell us how to run the demo of the DAC/ADC. In addition, it tells us how to use the signal tap to view the digital sinewave.
Try to test it.
Best regards,
Jeremy.
