Hello all!

I'm using IAR workbench to program a STM32 ( accessline lowdensity) via JTAG

Because we dont have ETM to do some trace and inspecte the data in real time, so we want to save the data or some variables in a file, and analysize it.

By using the DLIB_Full, i can compile and make the program work, but the problem is ''the time execute is so long'' when i do fopen fprintf and fclose, it slow down my system and all interrups.

HOW can i fix it?

How does the fprintf work with STM32? Are there a lot of data that was sent via the JTAG to PC?

Thanks
