void	setWriteError (int err=1)

Detailed Description

Provides debug output to stream (e.g. Serial) or delegate function handler.

Debug output may be prefixed with an elapsed timestamp. Use standard print methods to produce debug output. Sming CLI (command handler) may be enabled to provide control of debug output to end user.
