Connect to Kneron device

This tutorial shows how to connect to Kneron devices and get Kneron device handler (Device Group).

Import kp into your program:

import kp

---

Get Kneron device USB port IDs for connecting:

Device Group is Kneron device handler, which supports multiple same product ID Kneron devices connection ability.

1. Get USB port ID of KL520 devices by kp.core.scan_devices()

   target_device_type = kp.ProductId.KP_DEVICE_KL520
   usb_port_ids = []
   
   device_descriptors = kp.core.scan_devices()
   
   for device_descriptor in device_descriptors.device_descriptor_list:
       if target_device_type == device_descriptor.product_id and \
          device_descriptor.is_connectable:
           usb_port_ids.append(device_descriptor.usb_port_id)

2. Connect to Kneron device by kp.core.connect_devices(usb_port_ids=List[int])

   • Connect one Kneron device

     device_group = kp.core.connect_devices(usb_port_ids=[usb_port_ids[0]])

   • Connect multiple Kneron devices
     Note: Multiple Kneron devices connection ability only supports the same product ID Kneron devices. Please check your USB port IDs have the same product ID before kp.core.connect_devices(usb_port_ids=List[int]).

     device_group = kp.core.connect_devices(usb_port_ids=usb_port_ids)
