Printf to debug viewer(in Keil) on Cortex M0

Posted on January 02, 2013 at 23:20

Hello,

do STM32F0 support function, where printf output is forwarded to ''Debug (printf) Viewer'' in Keil not to UART?

Thanks

Trace (ETM, ITM, DWT) not available on Cortex-M0

The IDE can do it for you - go to 'Manage Run-Time Environment' and select the right option for STDOUT. In this case ITM.

For sure for non M0 devices - in this case not available on F0.

Hello

The 'USER' selection is normally used to redirect to hardware such as a UART.

Using ITM or EVR does not require a UART or other user hardware.

Attached is an updated version of the Keil ST-Link appnote. I will put this on Keil.com early next week:

See page 15 for the method to provide printf for STM32F0 Coretx-M0 processors. This will also work for other Cortex-M devices.
