Module signal_gen_cjds66_lib::command [−][src]
Expand description
Functions which communicate with the device over its USB-serial interface, and expose nearly all of its remotely-accessible features. This contains the support code and logic for almost everything the device can do.
Each function accepts a “verbose” integer parameter, which can be set to a number above 0 to enable a different and more verbose style of output which is useful for debugging, or to help understand what is happening behind-the-scenes when a function is run. Currently any number above 0 produces the exact same verbose output, so you can just use 1 for “verbose” output, and 0 for “not verbose” output.
