flash memory to ADSP-21065L

Started by "Allia Donna D. Go" June 26, 2007
Hi!

I'm planning to use a flash drive for memory expansion of ADSP-21065L.
To interface this (flash drive) to the DSP board, I will use a USB
female port to 9 pin female serial port connector. The 9 pin female
serial port is to be connected to the EMAFE of the DSP board and the
USB female port to the flash drive.

How can I connect the USB port to the serial port? Will that be a
simple pin to pin connections? Also, how can I interface the serial
port to the EMAFE of the DSP board?

Any help would be much appreciated.
Howdy Allia,

If it's really USB to RS232 serial, then get a USB to serial adaptor like
the CP-US-03. I don't know what the EMAFE is, so I can't help you there.

USB is a complicated pain in the butt, the signalling is far different
than the signalling on an RS232 line. You can't just connect them.

Patience, persistence, truth,
Dr. mike

Hi!

There is a USB gamepad project [1] that maybe can be useful to you. It
uses a serial port connected directly to a usb port, performing a usb
controller by software. You can find some useful things and
specifications in [2].
