Debug Traces

MicroUI logs several actions when traces are enabled (see Event Tracing). This chapter explains the trace identifiers.

Note

Most of the logs are only available on the Embedded VEE Port (not on the Simulator).

Trace format

The trace output format is the following:

[TRACE: MicroUI] Event AA(BB[CC],DD[EE])

where:

  • AA is the event identifier. See next table.

  • BB is the first event data.

  • CC is the index of the first event data (0x0).

  • DD is the second event data.

  • EE is the index of the second event data (0x1).

  • etc.

For example, given the following trace output:

[TRACE: MicroUI] Event 0x2(1[0x0],2[0x1],117571586[0x2])

  • 0x2 -> Execute native input event

  • 1 -> Event “Button” (index 0x0)

  • 2 -> Generator Id (index 0x1)

  • 117571586 -> event data (index 0x2)

Trace identifiers

The following tables describe some events data.

Warning

These tables are only compatible with the latest pack available (14.2.0).
