has anyone an "K70 with ULPI Interface" example? Does this work also with MQX-USB Libary?
I have an external USB Phy from SMSC (USB3320).
Dear Mr. Luis,
In the TWR-SER2, we use USB3300 and USB stack and MQX USB applications are using it in HS mode.
I think is a good starting point.
USB MQX examples for HS are the same examples used for FS. In order to use TWR-SER2, follow the getting started MQX doc:
USBFS (KHCI0) module – This BSP is pre-configured to use USBFS module by default. The USBFS is connected to USB HOST (USB A connector) only. USB device functionality is not available due to HW limitations.
USBHS (EHCI0) module – To enable USBHS (EHCI0) change BSP settings as follows and recompile BSP. The USBHS (EHCI0) is connected to USB OTG (USB mini AB connector)
#define USBCFG_DEFAULT_DEVICE_CONTROLLER (&_bsp_usb_dev_ehci0_if) #define USBCFG_DEFAULT_HOST_CONTROLLER (&_bsp_usb_host_ehci0_if)
TWR-SER2 – J21 (USB_VBUS_EN) shunt
Hk Kai Paulus,
The TWR-SER2 uses one of SMSC USB3300 first generation ULPI PHY. Please look at our website for newer PHYs which support more features such as 60 MHz input clock mode and improved setup time (+2ns). Other PHYS have USB battery charging etc.
