IU2FRL ICOM CI-V Python Library

Python library for communicating with iCOM radios using CI-V.

Compatible devices

Theorically speaking, all ICOM devices implementing the CI-V protocol should be compatible, in particular, the following devices were tested:

• IC-7300 (fw: 1.42)
• IC-7300 MKII (fw: 1.02)
  • Tested using the IC-7300 module
• IC-706 MKII
• IC-821H
• IC-9700 (fw: 1.43)

Usage

1. Installing dependencies

• Install the package using pip install iu2frl-civ

2. Importing the module

• Import the module using from iu2frl_civ.device_factory import DeviceFactory

3. Creating the device object

• Initialize the target device using radio = DeviceFactory.get_repository(radio_address="0x94", device_type=DeviceType.Generic, port="COM10")

[!TIP] Usage of named arguments (like radio_address="0x94") over positional arguments is highly recommended as it provides better support for future releases or library code reviews

Where:

• device_type = DeviceType.Generic is the type of device you want to control
• radio_address = 0x94 is the transceiver address

Then, additional arguments can be passed:

• port = "/dev/ttyUSB0": communication port of the transceiver
• baudrate: int = 19200: baudrate of the device
• debug = False: useful to troubleshoot communication issues
• controller_address = "0xE0": address of the controller (this library)
• timeout = 1: serial port communication timeout in seconds
• attempts = 3: how many attempts to perform in case of timeout or errors
• fake = False: if set to True, the library will use a fake connection to the transceiver (serial commands will be printed to the console and not sent to any port)

4. Use the radio object

Once the device object is created, any supported method can be used, for example:

• Power on the transceiver: device.power_on()
• Get the current frequency: device.read_operating_frequency()

5. Check the command output

Some commands have an expected value to be returned (like the device.read_operating_frequency()), most returns a boolean value, while other returns nothing (void). If the device does not support a command (or it was not yet implemented), or if some error occurred, an exception is thrown:

• NotImplementedError: the current device does not implement this feature yet
• CivCommandException: something went wrong in the data exchange between the transceiver and the library (probably due to device misconfiguration, faulty cables, etc)
• CivTimeoutException: the communication timed out (something wrong with wiring or connection parameters like port or baudrate)

6. Debugging

If some commands are not working as expected, the following code can be used to enable debugging:

import logging

logger = logging.getLogger("iu2frl-civ")
logger.setLevel(logging.DEBUG)

Sample code

[!IMPORTANT] Do not rename the tests folder or the fake_generic.py file, as those are used for testing the library.

Some sample commands are available in the tests folder.

• ic7300.py: A simple test script that demonstrates how to use the library to communicate with the IC-7300 transceiver.
• ic7300_clock.py: A simple script to set the clock of the IC-7300 transceiver by syncing to the PC.
• ic706_mkii.py: A simple test script that demonstrates how to use the library to communicate with the IC-706 MKII transceiver.
• ic821h.py: A simple test script that demonstrates how to use the library to communicate with the IC-821H transceiver.
• fake_generic.py: A simple test script that fakes a connection to transceiver, used to validate builds.
