Detailed Description

Resets the DS2482.

As with all command objects, you do not typically construct one of these objects. Instead, use the static run method to handle allocating, initializing, and queueing the command.

◆ run()

DS2482DeviceReset & DS2482DeviceReset::run ( DS2482 &  parent,
std::function< void(DS2482DeviceReset &, int status)>  completion 
)
static

Resets the DS2482.

Parameters
parentThe DS2482 you want to send the command to.
completionThe completion handler lambda function. status is the result status of the call; if DS2482Command::RESULT_DONE then the call succeeded.

This call executes asynchronously. The completion function is called when complete or an error occurs.
