How to make printf print on Putty via UART

David Lee

Hi, I use STM32F4 discovery board with Keil MDK-ARM 5 on a 64-bit Windows 10 machine.

I used UART functions like USART_SendData, which was provided from ST, to print messages on Putty.

Can I achieve the same UART message using the printf function?

I hope there is some kind of retarget feature.

Also, do I need Keil's MIcroLib to achieve this?

-Best Regards
