SerialUSB question

Post by asmallri » Mon Jan 15, 2018 4:57 pm


How can I determine if a Bluepill is attached via USB versus connected? I want to find out if a Bluepill is plugged into a device as opposed to having an open serial connection to the device.

Is the statement

Code: Select all

the equivalent of

Code: Select all

Thanks, Andrew
