Discussion - Software / V2DIP1-32 SPI2DSC example USB_HOST never enumerated
« on: August 05, 2020, 10:07:29 AM »
Hello,
I'm using the V2DIP1-32 development module with the VNC2 debug module.
I want to implement a data transfer between SPI and USB mass storage.
Unfortunately the SPI2DSC example (https://www.ftdichip.com/Support/Documents/AppNotes/AN_186_VNC2_SPI_to_USB_Memory_Bridge.pdf) does not recognize my USB device.
It does not get out of the loop in line 273 of SPI2DSC.c where checking usbhost_connect_state:
I've tried two different FAT32 USB Sticks, both with the same result.
Best regards
Jonas

while (usbhost_connect_state(hUSBHOST_1) != PORT_STATE_ENUMERATED)
I've tried two different FAT32 USB Sticks, both with the same result.
