Implementing a 'live watch' window in C# test app using ST-Link

I'd like to implement something like IAR's EWARM 'live-watch' window in a C♯ app on a PC to interrogate firmware values via an ST-Link. I'd use this for production testing or diagnostics. The 'live watch' window in EWARM will read parameters over an ST-Link without pausing execution of firmware. It also allows writing too.

In lieu of this, we use a UART or CAN bus but it would be nice to eliminate redundant hardware connections and use the ST-Link since it's needed for initial programming anyway.Does anybody do this? Is there an API or DLL available to implement this type of communications?-Jim #api #st-link-c

And of course Segger makes a business out of JTAG and programming automation, with DLL/LIB support.Test points for JTAG and USART connectivity aren't hugely burdensome.

Hello,

Maybe have a look at STM Studio software :

There is no dll or api you can use with this soft but it can be used to diagnose/test your appli without modifying your appli code. Rgds, Laurent

The SOMNIUM DRT Cortex-M IDE also supports live viewing of variables / expressions while debugging:

So is that like 3 guys with 33+ years in the industry? Your copy editor must have thought that sounded good, it just has me scratching my head.
