Hi Anders Yes, I added studio.h in the main.c I just only want to use Printf for debug. Could you help to check this issue in DT2 mouse. I know Printf can be used in SDK but it cannot work in DT2. Thanks.

Hi. Have you included stdio.h? Printf will print to stdout, which means that a printf to stdout must be mapped to printing to the uart. The function fputc must implement hal_uart_put_str(). You can see how this is done inside retarget.c in for example the nus example.

int fputc(int ch, FILE * p_file)
{
    UNUSED_PARAMETER(p_file);

    UNUSED_VARIABLE(app_uart_put((uint8_t)ch));
    return ch;
}
