Hi all, i need to sample some signals from the slow adc, but i don't want to lose any sample.
I have two paths, or changing the fpga project, and adding an AXI stream port to the ADC Wizard and then connect it to the PS through a DMA, or using the linux industrial driver (IIO) and connect the buffer in:
sys/devices/soc0/amba_pl/83c00000.xadc_wiz/iio:device1/
Any idea or example?

Re: Adquiring continuos data from slow ADC
Hi,
Maybe a simpler option could be to use an AXI Stream FIFO instead of a DMA.
I would say that the data rate of the XADC (<1MSps) is sufficiently low not to lose any sample.

Below are some blocks connected in Vivado as an example but I did not check if it works...
