Hello,

I am using an STM 32 F401 Nucleo and i want to send numbers from PC via UART.

For example I need to set the frequency and amplitude.

Can some one help me to provide the code?

Thank you in advance.

    Should be able to use USART2 via PA2/PA3, buffer inbound data, parse, and process with sscanf(), etc.

    Might want to start with output, and adapt

    Andrei, in your STM32CubeF4 package you should find UART examples (Polling, IT and DMA) for your Nucleo board. Download it from here if you don't have it yet:
