I suggest if you are interested in this system you make
a folder and drag over all the many future messages on this
subject otherwise delete it.

I am just getting mine talking to my XP computer.
If you plan to use the USB rather than the RS232 port for communicating
you must do this.
You will need to download USB drivers from the FTDI site and install
them manually. The FT232R drivers are available directly from FTDI at
http://www.ftdichip.com/Drivers/VCP.htm. Note that the CDM driver (whatever
that is) is not available for all operating systems. Be sure to download
the drivers for the FT232R device that match your OS.

"The jumpers and switches are set at the factory assuming
that the Dev Board will be powered via the on-board
regulator and that a standard serial port will be used for
communication with the ZX-1280N. If this is how you
intend to operate it, simply connect an external supply to
J27, connect your serial cable to J25 and activate the
power switch. You should then see the output from the
default ?Hello, world? program, confirming that the ZX-
1280N is operating correctly and ready to accept your
program."
"If you intend to use the USB interface, several additional
steps will be required. Firstly, change the switch SW3
to the ?USB? position. If you also intend to power the Dev
Board from your USB hub, move jumper J19 to the
?USB? position as well. Otherwise, connect an external
power supply to J27. Connect a standard USB A-B
cable between J28 of the Dev Board and your USB hub. When
the power switch is activated, you should see
several flashes on the Red/Green LED (D4, near the J28
connector). "
I got it working with the USB and an external power supply.
There is a blinking LED near the USB connector on the board when
it is communicating with the PC. This is what the screen
in the Windows XP computer looks like.
The next test will be the rotary engine compression tester
program. If you have the board and you want to follow along
and you run into a problem I'll try to help.
---------------------------------------------------
The compression tester is working. It took 5 minutes
to write the software and get it working.
I had no pressure sensor connected to the A to D pin so it was
reading max high or 254 and 255.
One minor problem.
I need to convert the extended ASCII output characters
to a decimal number character so they can be loaded into
a spread sheet for plotting.
Anybody know how to do this in debug?
A Windows problem.
