Hello

I have a board Nucleo-F103RB. 

I cut a usb cable and connect:

D+ to PA11 

D- to PA12 

GND to GND pin in morpho headers 

VCC to E5V pin in morpho headers

I am using the libraries. STM32_USB-FS-Device_Lib_V4.0.0. 

And i want make a HID dvice so I copi the source code to my IAR proyect

I use this functions in main function.

  Set_System();

  USB_Interrupts_Config();

  Set_USBClock();

  USB_Init();

    while (1)

    {

    }

But it don't make nothing the PC don't recog

Compile and execute but it don't make nothing the PC does not identify the a new device connected.

What am I making bad?

I must instal first the PC driver?

Where can i find a example code?

Some one can help me?

Best regards

Hello

I am making probes and i see that the codee stop in:

startup_stm32f10x_md.s

 

 

 

USB_LP_CAN1_RX0_IRQHandler

 

        B USB_LP_CAN1_RX0_IRQHandler  <--- This line

 

 

 

        PUBWEAK CAN1_RX1_IRQHandler

 

        SECTION .text:CODE:REORDER:NOROOT(1)

So... I create a USB.C and USB.H file where I put the next funtions

void USB_HP_CAN1_TX_IRQHandler(void)

 

{

 

  OutStringUART_PC(''USB_HP_CAN1_TX_IRQHandler \r\n'');

 

}

 

void USB_LP_CAN1_RX0_IRQHandler(void)

 

{

 

  OutStringUART_PC(''USB_LP_CAN1_RX0_IRQHandler \r\n'');

 

}

 

void USBWakeUp_IRQHandler(void)

 

{

 

  OutStringUART_PC(''USBWakeUp_IRQHandler \r\n'');

 

}

 

 

 

void EXTI9_5_IRQHandler(void)

 

{

 

  OutStringUART_PC(''EXTI9_5_IRQHandler \r\n'');

 

}

I open a hiperterminal and I only view 

 

EXTI9_5_IRQHandler

What I must make???

This interrupt is the USB cable detection???

Best regards.
