| Tracealyzer Stream Port for ARM Cortex-M ITM | |
| -------------------------------------------- | |
| 2018-05-04 | |
| 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), | |
