AD9625 Register Configuration + Linux

Hello,

I´m working with the AD-FMCADC2-EBY FMC BOARD connected to a VC707 board.

The reference design works fine with the remote oscilloscope test program, but right now I am trying to control the ADC throught the embedded linux system running on the FPGA.

 

There are some examples codes o some kind of documentation that I could take as a reference? I just want to read some samples of the DAC and send them through the UART.

I am having troubles also finding the location of the configuration register of the ADC Register Map [Analog Devices Wiki]. The ADC is configured through SPI, so this standard configuration register interface should be stored in somewhere, readed from the OS and sent to the SPI to configure the ADC. Maybe in the reference design is configured on the fly by the OS.

 

Regards and thanks for your time.

 

Pablo.
