In WF_SDK/static.py, calling the .set_state() method will raise operand mismatch error between the mask and shifted bits.
This can be fixed by adding mask = mask.value at line 134 just like line 68.

I have an Analog Discovery 2 device connected through Rasberry Pi 4. I installed the latest version of Adept Runtime(2.26.1) and WaveForms(3.18.1) on the RPi device according to the instructions here: https://digilent.com/blog/analog-discovery-2-is-now-compatible-with-raspberry-pi-4/. WaveForms app works fine via GUI interface.
But I have one issue with configure power supplies when I try to use WaveForms SDK in python scripts.
I configured the "positive" power supply to 3.3V and I tried to read state from static DIOs. I got a "LOW" state on all DIO inputs, although there should be a "HIGH" state on the DIO inputs according to my scheme.

I tried to run my script on Windows 10 and I got the expected result.

My examples can be found here:

from WF_SDK import device, static, supplies, error  # import instruments
from time import sleep  # needed for delays

try:
    # connect to the device
    device_data = device.open()
    print("Device name: " + device_data.name)

    # start the positive supply
    supplies_data = supplies.data()
    supplies_data.master_state = True
    supplies_data.positive_state = True
    supplies_data.state = True

    supplies_data.voltage = 3.3
    supplies_data.positive_voltage = 3.3
    supplies.switch(device_data, supplies_data)

    # set 9,10,11 pins as input
    static.set_mode(device_data, 9, False)
    static.set_mode(device_data, 10, False)
    static.set_mode(device_data, 11, False)

    try:
        while True:
            reading_dio9 = static.get_state(device_data, 9)
            print("DIO9: ", reading_dio9, end=' ')
            sleep(0.1)

            reading_dio10 = static.get_state(device_data, 10)
            print(" DIO10: ", reading_dio10, end=' ')
            sleep(0.1)

            reading_dio11 = static.get_state(device_data, 11)
            print(" DIO11: ", reading_dio11)
            sleep(1)

    except KeyboardInterrupt:
        # stop if Ctrl+C is pressed
        pass

    finally:
        # stop the static I/O
        static.close(device_data)

        # stop and reset the power supplies
        supplies_data.master_state = False
        supplies_data.positive_state = False
        supplies_data.negative_state = False
        supplies.switch(device_data, supplies_data)
        supplies.close(device_data)

        # close the connection
        device.close(device_data)

except error as e:
    print(e)
    # close the connection
    device.close(device.data)

Do you have any idea how to solve issue with Raspberry PI ?

I just installed the latest version of WaveForms (3.18.1) on Windows 10, and afterwards installed the SDK through pip3 install git+https://github.com/Digilent/WaveForms-SDK-Getting-Started-PY#egg=WF_SDK.
Now, when launching Python (3.7.12) and importing the scope module via from WF_SDK import scope I get AttributeError: module 'dwfconstants' has no attribute 'DwfWindowRectangular'
I can see in the dwfconstants.py file that indeed this attribute is not present. Can either the code or the constants file be updated so that they are compatible?

Hello and thank you for this work,

I want to program the IN/OUT of the Analog Discovery 2, and when I try to use your example "test_static-supplies.py", I encounter this error in static.py:

Exception has occurred: TypeError
'c_ushort' object cannot be interpreted as an integer
File "/home/douadiag/Bureau/WaveForms-SDK-Getting-Started-PY-master/WF_SDK/static.py", line 138, in set_state
if dwf.FDwfDigitalIOOutputSet(device_data.handle, ctypes.c_int(mask)) == 0:
File "/home/douadiag/Bureau/WaveForms-SDK-Getting-Started-PY-master/test_static-supplies.py", line 36, in
static.set_state(device_data, index, not(mask & pow(2, index)))
TypeError: 'c_ushort' object cannot be interpreted as an integer**

Could you please help me resolve this error?

Thank you.
