 /* USER CODE BEGIN 2 */

 /* USER CODE END 2 */

 /* Infinite loop */

 /* USER CODE BEGIN WHILE */

 while (1)

 {

  /* USER CODE END WHILE */

Hello.

Have you got this error "../Src/main.c:126:2: warning: implicit declaration of function 'CDC_Transmit_FS' [-Wimplicit-function-declaration]"?

If yes, then try "#include "usbd_cdc_if.h"" in section "/* USER CODE BEGIN Includes */"
