THANK YOU SO MUCH!!! The biggest thing was changing the pins to an ST-LINKED pin. You rock!!!

You can buy usb to ttl serial converter and use it. Code will remain same

Thanks! got it working with this tutorial

[@yasirshahzad3732]

// Override this function : int _write(int file, char *ptr, int len) { HAL_UART_Transmit(&hlpuart1, (uint8_t*)ptr, len, HAL_MAX_DELAY); return len; }

[@tm-uz7md]

Makes no sense. How does the _write function get invoked ? All you have is a printf statement that won't do it.

[@GuiMVII]

Great video, really helpfull!

[@dsvignesh1523]

i am using putty but I am getting garbage value. tried with other tools also but still getting the garbage value.

[@viduraembedded6369]

Pls check the buadrate configuration and use the same buadrate in putty
