Control Command Execution Example

The standard control command "TD-USB" from Tokyo Devices is used.

(Retrieve current value)
> td-usb tdsn604xx get
1.2331 ← Value returned in amperes

(Repeated retrieval every 100 msec)
> td-usb tdsn604xx get --loop=100
1.2331
1.3281
1.33204
...

(Record values to a text file)
> td-usb tdsn604xx listen --loop > current.txt

To integrate with a user application, call the TD-USB command externally from a program. It can be used with Python, shell scripts, C#, and more. Refer to the TD-USB documentation for integration samples.

Additionally, the demo application "TD-AppKit" can be used for graph display (Windows only).
