Figure 47 shows the use of SWV in ST-LINK Utilities. Figure 47. SWV in ST-LINK utility Refer to STM32 ST-LINK utility software description user manual (UM0892) for details. Tip: Keil® MDK-ARM µVISION and ST-LINK utility SWV allows to select the Stimulus to display. On the other hand it is quite straight forward to make some clone of ITM_SendChar() function using any of the 31 stimulus port. Can be useful in a very verbose system to set a trace library which split trace between stimulus based on their importance (info, debug, error) or there source. 7.4 Semihosting Semihosting is a mechanism that enables code running on an ARM® target to communicate and use the Input/Output facilities on a host computer that is running a debugger. Examples of these facilities include keyboard input, screen output, and disk I/O. For example, this mechanism can be used to enable functions in the C library, such as |
