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

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

[@KanagachidambaresanGR]

i am getting special character., what would be the pbm

[@tm-uz7md]

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

[@woldecosgrove]

if i connect USB cable to PUTTY can i still see the Current number displayed 1..... ??

[@viduraembedded6369]

Yes

[@honeymadhu6007]

Sir, how to get this development board ?

[@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

[@DereC519]

i dont have a serial port, any help? The option is blank

[@viduraembedded6369]

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