Possible to use precision ADC in FPGA without passing by OS

[kth7316]

Hello,
Is it possible on Alpha250 to use precision ADCs without passing by the C++ and directly with the FPGA ?
I try to find some examples but without success. And the way you do it in the C++ precision adc driver doesn't help me a lot ...
Thanks again

Hi,

The precision ADC SPI bus is connected to the FPGA (PL IOs bank 34), see user guide for details.

In the base design it is then connected to the Cadence SPI controller in the PS, but you can connect it to your how SPI controller in the FPGA.

You can for example connect it to both the cadence hard core using the C++ driver for configuration and only read the data packets on the FPGA using a simpler core ...
