    • No console ouput

    Hey guys,

    I'm trying to develop a code on a STM32F401C-DISCO board with the System Workbench for STM32 on Eclipse. I can build my code and debug it successfully but in debug mode, I can't use printf() or scanf(), the Program Output Console still remain empty 😑. I probably made a wrong configuration somewhere but I can't find it.
    I'm using OpenOCD 0.9 and AC6 STM32 Debugging. Hope you could help me !

    Thanks in advance,

    Max

    Hi Max,
    Welcome to the world of embedded systems. Your discovery board does not have a console unless you build one. If you google "stm32f4-disco console" You will find information on how to do this and you will then know more about it than me.

    I should look into that. In the mean time I have used buttons and such for user inputs. I'm working up to using touch on the STM429I-DISCO.

    Another interesting I/O option would be a small radio like the nrf24l01 or the esp8266.

    best,
    hank
