virtual serial on USB problem STM32F103

ciao ..!!

I use STM32F103C8Tx, my IDE is Atollic and configure the project with STM32CubeMX

I wanted to try to use the virtual serial present in Cube but I have some problem.

I enabled the USB Device and added the class Virtual Com Port

first of all in the Main.c I include:

#include ''usbd_cdc_if.h''

in ''While (1)'' i use the function of the class for send every second a ''hello''

uint8_t msg[] =

''hello''

;

while

(1)

{ CDC_Transmit_FS(msg,5);

HAL_Delay(1000);

}

Ok ... This code seems really simple but the debugger always stops in the function:

void

HardFault_Handler(

void

)

{

while (1)

{

}

I also tried to make some modifications to the ''usbd_cdc_if.c'' file but without any solution

I hope someone can help me and explain a solution to this problem

Thank you and good day, Marco

Hello,

Refer to user manual

on how to use the STM32Cube USb device library,

You can find under the STM32CubeF1 package a set of applications about USB device which can help you as an implementation example:

STM32Cube_FW_F1_V1.3.0\Projects\STM3210C_EVAL\Applications\USB_Device

Hope this helps you.
