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 ?
