It depends on what you want to read off of Flash drive. If you can use drive’s serial number, which is unique for the drive, this can be done with the code which is already written since it’s just a string descriptor. If you need full support for flash drive, then you would need to write it – currently, flash drives are not supported.

As far as programming, it’s standard Arduino package from arduino.cc.

I’m not sure what you mean by “SPI to USB”, but if you are trying to send data to the PC via USB using MAX3420, you first need to perform enumeration and start appropriate driver on a PC.

Hi,

I am trying to implement spi to usb with the max3420e. I am using a FPGA to talk to the max3420e.
Do I need to check any USB interrupt registers or pins.
These are the steps I am following -

1. Make SS low and write command byte to register R17 (PINCTL) to enable Full duplex SPI
2. Make SS low and select EP2INFIFO register and write data bytes
3. Make SS low and select EP2INBC register and write the # of data bytes written

This should make data appear on the PC, right?
I had a notepad open. Nothing happened.
But it doesn’t work. I tried writing to GP0 register and it works. So I am able to talk to the MAX3420.
Any help would be great.

Thanks.
