Detailed Description

The UARTDebugger class adds debugging support to a UART bus.

It accumulates bytes that travel over the UART bus and triggers one or more actions that can log the data at an appropriate time. What 'appropriate time' means exactly, is determined by a number of configurable constraints. E.g. when a given number of bytes is gathered and/or when no more data has been seen for a given time interval.

Member Function Documentation

◆ add_delimiter_byte()

void esphome::uart::UARTDebugger::add_delimiter_byte ( uint8_t byte )

inline

Add a delimiter byte.

This can be called multiple times to setup a multi-byte delimiter (a typical example would be '
'). When the constructed byte sequence is found in the data stream, logging will be triggered.

Definition at line 26 of file uart_debugger.cpp.

◆ set_after_bytes()

void esphome::uart::UARTDebugger::set_after_bytes ( size_t size )

inline

Set the maximum number of bytes to accumulate.

When the number of bytes is reached, logging will be triggered.

Definition at line 33 of file uart_debugger.h.

◆ set_after_timeout()

void esphome::uart::UARTDebugger::set_after_timeout ( uint32_t timeout )

inline

Set a timeout for the data stream.

When no new bytes are seen during this timeout, logging will be triggered.

Definition at line 37 of file uart_debugger.h.

◆ set_direction()

void esphome::uart::UARTDebugger::set_direction ( UARTDirection direction )

inline

Set the direction in which to inspect the bytes: incoming, outgoing or both.

When debugging in both directions, logging will be triggered when the direction of the data stream changes.
