How Do I List All Connected Devices And Their IDs?#
Once your devices are connected, you can use the get_device_map
method to inspect them.
method1#
from sinabs.backend.dynapcnn.io import get_device_map
from typing import Dict
device_map: Dict[str, 'DeviceInfo'] = get_device_map()
print(device_map)
This should produce an output that looks something like below:
>>> {'speck2fdevkit:0': device::DeviceInfo(serial_number=, usb_bus_number=2, usb_device_address=9, logic_version=0, device_type_name=Speck2fDevKit)}
method2#
import samna
# Get device infos of all unopened devices
deviceInfos = samna.device.get_unopened_devices()
# Print device infos to see what devices are connected
for info in deviceInfos:
print(info)
This should produce an output that looks something like below:
>>> device::DeviceInfo(serial_number=, usb_bus_number=2, usb_device_address=9, logic_version=0, device_type_name=Speck2fDevKit)
How Do I Open The Device#
import samna
deviceInfos = samna.device.get_unopened_devices()
# Select the device you want to open, here we want to open the first one
device = samna.device.open_device(deviceInfos[0])
or you can just pass the devkit’s name to the open_device
function
import samna
speck = samna.device.open_device("Speck2fModuleDevKit")
All devices that supported by samna can be found at here.
How Do I Reset The Device#
method1(hard reset)#
Just press the reset button on our devkit!
method2(soft reset)#
import samna
# open device
speck = samna.device.open_device("Speck2fModuleDevKit")
...
...
...
# reset devkit, this operation will apply a default configuration to the devkit
speck.reset_board_soft(True)
How Do I Close The Device#
import samna
# open device
speck = samna.device.open_device("Speck2fModuleDevKit")
...
...
...
# close device
samna.device.close_device(speck)
