Member Data Documentation

◆ Protocol

TpiuProtocol TpiuOptions::Protocol

Selected protocol.

Not every protocol might be available on each MCU, refer to vendor documentation for details. For parallel trace, specify trace port width in TracePortWidth field. For SWO protocol, specify baudrate in SwoPrescaler field.

◆ FormattingEnabled

bool TpiuOptions::FormattingEnabled

Include TPIU framining in output data.

TPIU can output data from ITM/ETM without any additional formating (false) or wrap it in additional layer (true). That additional layer allows to identify trace source that produced it each packet as it include TraceBusID value (which is set when configuring ITM or ETM).

Remember that receiving tools probably will need to know if formatting is enabled and if it is enabled - TraceBusID of each source

◆ SwoPrescaler

int TpiuOptions::SwoPrescaler

Prescaler for SWO output data.

When one of SWO protocols is selected, this field will determine output speed. For Manchester encoding receiver should automatically detect data rate, for UART receiver needs to know exact baudrate. Baudrate is calculated as: \(Baudrate = \frac{TraceClock}{SwoPrescaler}\)

◆ TracePortWidth

uint8_t TpiuOptions::TracePortWidth

Number of bits in parallel trace port.

When using parallel trace protocol it is possible to define number of data lines used to outputing data.
