Tracealyzer Stream Port for ARM Cortex-M ITM
This directory contains a "stream port" for the Tracealyzer recorder library,
i.e., the specific code needed to use a particular interface for streaming a
Tracealyzer RTOS trace. The stream port is defined by a set of macros in
trcStreamingPort.h, found in the "include" directory.
This particular stream port targets ARM's ITM interface, which together with
a fast debug probe such as a Keil ULINKpro or ULINKplus provides excellent
performance. This stream port does not use any RAM buffer for the trace, but
writes the data directly to the ITM registers. This is very fast.
To setup Keil uVision for ITM tracing with a Keil ULINKpro (or ULINKplus),
see Percepio Application Note PA-021
