USB HS core in FS mode

Posted on July 03, 2015 at 22:56

Hi,

I am using a stm32f427 as a USB host/MSC class, with the host library from the STM32F4-Discovery_FW_V1.1.0 package.

My question is, if I want to use the HS core in FS mode, how should I set the defines in usb_conf.h?

Should I use:

#define USE_USB_OTG_HS or #define USE_USB_OTG_FS?

I call the USBH_Init() with coreID parameter set to USB_OTG_HS_CORE_ID, so the HS core is chosen.

First I used USE_USB_OTG_HS, but could not get the code to work. The device was not enumerated.

Then I changed to USE_USB_OTG_FS and it worked! So I just wanted to chek if this is the correct setting for HS core in FS mode?

Thanks

Peter
