"How can I send and receive datas by using STM32F103C8T6 USART pins with FTDI (3.3-5V) programmer and ST-Link V2 ?

Hi,

Nowadays I am trying to send and receive data with STM32f103C8 module. In fact, my aim is only write" Hello World " one after the other in the rows below at Tera Term, by coing at STM CubeIDE, and with my some hardwares. So , first I connected this STM32f103C8 module to an FTDI programmer module and ST-Link V2. By watching some videos, I connected these 3 products's pins:

STM32F103C8's Rx to FTDI's Tx,

STM32f103C8's Tx to FTDI's Rx ,

Ground to Ground,

STM32F103C8's 5V to FTDI's VCC pin, then, same legs of STM32F103C8's and ST-Link are connected to each other.

I used STM CubeIDE as developement environment, and Tera Term application to test it. When I build the project at STM CubeIDE, I get no error, but then When I Debug, then Resume(F8), there is no joy at Tera Term, and at STM CubeIDE a new page is openning named 0x1fffe61c which has explanation " Break at address "0x1fffe61c" with no debug information available, or outside of program code." inside this page.

Note : Baudrate is 115200 at both STMCubeIDE pinout configuration and Tera Term serial port settings.

The Hardwares that I used :

1. An STM32F103C8 module
2. An FTDI programmer(3.3-5V)
3. An ST-Link V2
4. A laptop with internet

The Softwares that I used :

1. STM32CubeIDE
2. Tera Term
