How to Use Control Commands

Use the Tokyo Devices standard control command “TD-USB.”

(Get a value)
> td-usb tdsn7502 get
133   (← weight is returned in grams)

(Get values continuously every 3 seconds)
> td-usb tdsn7502 get --loop=3000
100
102
105

(Log values to a CSV file every 3 seconds)
> td-usb tdsn7502 get --loop=3000 > log.csv

To integrate with a user application, call TD-USB as an external command from your program. It can be used from Python, shell scripts, C#, LabVIEW, and other environments. For details, refer to the datasheet and the integration examples in the TD-USB documentation.
