How to set up board without the native software

[Hanros94]

Hi Fabian

Could you please tell me how to initialise the board without first running the native software. I understand that there is the init function however when I run the script below, I don't see any changes in the frequency in channel 0. To reiterate I can set the frequencies using this module after I have first set the frequency in the native software.

`import evalcontrol
import time

evaluation_board = evalcontrol.AD9959()

#evaluation_board._reset_usb_handler()
evaluation_board.init(vid=0x0456, pid=0xee25, port_numbers=None, bus_number=None, auto_update=True,
rfclk=20e6, clkmtp=20, channel=0)
evaluation_board.set_frequency(2e6, channel=[0])

`

Hi Roshan,

from your other issue I take that you have solved this problem? Would you mind sharing your solution?

Cheers

Fabian

Hi @Hanros94,

I'm using this library and am running into the same problem as you. Any chance you'd be able to share your solution?

Thanks,

Dear Duncan I am sorry it has been four years, I cannot remember the solution. Kind regards Roshan

After some debugging, I've found a bandaid fix for this issue. It seems there's some intialization routine that the AD GUI does that is needed to start using the board. I used the function below to copy that routine. No idea if this will carry over to other boards/systems.

    def manual_init(self):
        """
        Copies the initialization routine of the Analog Devices GUI by sending the same
        commands as seen when using a USB sniffer.
        """

        # list of all commands sent by the AD9959 GUI on initialization (from USB sniffer)
        # all commands that are "unnecessary" for API use have been commented out
