dear LP55s69 ,

In the SDK, which USB demo code demonstrate the HS capability?

My customer I-Blades is looking for the dev_msc_sdcard_bm code but he want to use high speed usb port.

REgards,

Hello Hy Mai,

Sorry It seems there isn't USB High Speed demo for LPC55s69 so far.

Have a great day,
TIC

Hello Hy Mai,

I just test on my side, it is easy change the demo dev_msc_sdcard_bm to HS USB:

Only need change the code in usb_device_config.h file:

/*! @brief LPC USB IP3511 FS instance count */
#define USB_DEVICE_CONFIG_LPCIP3511FS (0U)
/*! @brief LPC USB IP3511 HS instance count */
#define USB_DEVICE_CONFIG_LPCIP3511HS (1U)

Have a great day,
TIC

I have been able to change the USB from full speed port to the high speed port but did not try to set to high speed.
