Detailed Description

Redesigned UART command parser with word-based commands.

Constructor & Destructor Documentation

UartCommandParser()

UartCommandParser::UartCommandParser ( uart_port_t uart_port )

inline

Construct a UART command parser bound to a specific UART port.

Configures the UART driver for non-blocking reads and line-based parsing. On ESP32-C6, UART0 is often already configured by the console; this constructor tolerates that case.

Parameters

uart_port

UART port to use (e.g. UART_NUM_0).

Member Function Documentation

ParseCommand()

bool UartCommandParser::ParseCommand ( const std::vector< std::string > & tokens, ParsedCommand & cmd )

inlineprivatenoexcept

Convert tokens into a structured ParsedCommand.

Parameters

tokens	Token vector as returned by Tokenize().
cmd	Output structured command.

Returns

true if parsing succeeded; false otherwise.

Here is the call graph for this function:

ParseCommandType()

CommandType UartCommandParser::ParseCommandType ( const std::string & token )

inlineprivatenoexcept

Map a verb token (first token) to a CommandType.

Parameters

token

Lowercase verb token (e.g. "set", "start").

Returns

Parsed command type. Unknown verbs map to HELP.

ProcessCommand()

bool UartCommandParser::ProcessCommand ( const char * line, FatigueTest::FatigueTestMotion & motion )

inlinenoexcept

Parse and execute a single command line.

Parameters

line	Null-terminated command line.
motion	Motion controller to operate on.

Returns

true if the command executed successfully; false otherwise.

Note

This function routes to the Handle* command handlers.

Here is the call graph for this function:

ProcessUartCommands()

void UartCommandParser::ProcessUartCommands ( FatigueTest::FatigueTestMotion & motion )

inlinenoexcept

Poll the UART for input and process complete lines.

Reads any currently buffered bytes (non-blocking) and accumulates them into a line buffer. When a newline is received, the line is executed via ProcessCommand().

Parameters

motion

Motion controller to operate on.

Warning

This runs in a polling task. Keep per-call work bounded.

Here is the caller graph for this function:

Tokenize()

std::vector< std::string > UartCommandParser::Tokenize ( const char * line )

inlineprivatenoexcept

Split a command line into tokens.

• Splits on whitespace
• Preserves quoted substrings (double quotes)

Parameters

line	Null-terminated command line string.

Returns

Token vector (may be empty).
