Hello!
I bought evaluation board: stm32f723e-disco
I want to communicate
stm32f7
23e-disco
with PC through USB cable through virtual com-port
I use Keil as IDE.
Where can I find example project to start working with usb?
Thank You!

Hello
Kashuba.Dmitry
,As there is no CDC example in the
STM32CubeF7
with STM32F723E-Discovery device, you can start with another working USB example andget inspired from this'CDC_Standalone'
application, it may helpf you :STM32Cube_FW_F7_V1.7.0\Projects\STM32F769I_EVAL\Applications\USB_Device\CDC_Standalone

Hi,
You find a readme.txt file describing how to use and test the example. You should follow the instructions detailed in this file.

I also have another question.
I use Keil v.5
1. I opened the project in folder STM32Cube_FW_F7_V1.7.0\Projects\STM32F769I_EVAL\Applications\USB_Device\CDC_Standalone\MDK-ARM
2. in file 'main.c' in function 'int main (void)' I found function 'USBD_Init(&USBD_Device, &VCP_Desc, 0)';
3. in the definition of the function
'USBD_Init()' I found function 'USBD_LL_Init(pdev);'
4. in
the definition of th
e
function'USBD_LL_Init();' I found function 'HAL_PCD_Init(&hpcd);'
5. in the
definition of th
e
function'HAL_PCD_Init();' I found function 'HAL_PCD_MspInit(hpcd);'
6. in the
definition of th
e
function 'HAL_PCD_MspInit();' in file 'stm32f7xx_hal_pcd.c' I DIDN'T FIND THE CONFIGURING OF THE GPIOs FOR USB
7. through the search in file 'usbd_conf.c' of this project I found another definition of the function '
HAL_PCD_MspInit();'
where GPIOs are configured for USB!!!!!!WHY THE DEFINITION OF THE FUNCTION '
HAL_PCD_MspInit();' IS IN FILE 'stm32f7xx_hal_pcd.c' (__weak void HAL_PCD_MspInit(PCD_HandleTypeDef *hpcd)), BUT NOT IN FILE '
usbd_conf.c' (void HAL_PCD_MspInit(PCD_HandleTypeDef *hpcd))?
Thank You!

Hi!
while programming stm32f723 through st-link utility, error 0x08004000 was occurred.
What does the error
0x08004000 mean?
What does the error 0x08000CB4 mean?
Thank You!
