Hi, i'm a new user of this board and i have a (maybe trivial) question. Searching on the web i found that there is a ''ITM_SendChar()'' instruction that could be very useful for me, but i can not view its result on my Eclipse IDE. Is there a way to configure eclipse in order to correctly use this function?

thanks in advance.

It would presumably depend on the debugger that you've integrated, and if that supports the SWV (Serial Wire Viewer).

I'm using the gdb debugger and sincerely i don't know if the SWV is supported...

I was thinking of the hardware and the drivers. You're posting under the STM32 Discovery forum, but it's not clear what board, or debug hardware, you have.

Atollic is Eclipse/GCC/GDB based, and supports SWV so looking at how it does it, and what pieces it needs might be instructive. I've used SWV under Keil on a couple of targets, but the support depends a lot of the debug pod being utilized, and SWV doesn't lend itself to streaming, in that regard a serial port works a lot more effectively. I'm pretty sure some of the older JLink and ULink pods don't support SWD/SWV particularly well.
