kvrlib examples¶
The following sections contain sample code for inspiration on how to use Kvaser Python kvrlib.
Connect to your remote device¶
Use the discovery functions to scan and connect to a remote device. Our remote device has serial number 16 and is already connected to the same network as our computer:
from canlib import kvrlib
SERIAL_NO = 10545
print("kvrlib version: %s" % kvrlib.getVersion())
print("Connecting to device with serial number %s" % SERIAL_NO)
addressList = kvrlib.kvrDiscovery.getDefaultAddresses(kvrlib.kvrAddressTypeFlag_BROADCAST)
print("Looking for device using addresses: %s" % addressList)
discovery = kvrlib.kvrDiscovery()
discovery.setAddresses(addressList)
deviceInfos = discovery.getResults()
print("Scanning result:\n%s" % deviceInfos)
# Connect to device with correct SERIAL_NO
for deviceInfo in deviceInfos:
if deviceInfo.ser_no == SERIAL_NO:
deviceInfo.connect()
print('\nConnecting to the following device:')
print('---------------------------------------------')
print(deviceInfo)
discovery.storeDevices(deviceInfos)
break;
discovery.close()
This results in the following:
kvrlib version: 2070
