STM32F479IIT6

Posted on July 04, 2018 at 12:19

we are using STM32F479IIT6 in our design as below,

1.USB 2.0 full speed

2.Self powered

3.As device

Could you clarify on the following points,

1.what is default configuration of OTG_FS_ID(left unconnected,GND or pullup)

2.since it is self powered,there is no need of 5V supply(VBUS is used for sensing of host connection)

Thanks,

Arun D.

Hi Khouloud,

I have referred the attached application note however it is not mentioned about OTG_FS_ID, also given snapshot below.

As ID pin is required in OTG applications only, can with go with unconnected.

Kindly help us in getting configuration of OTG_FS_ID in USB 2.0 full speed as a device/peripheral.

Thanks,

Arun D.
