G'day,
currently we have the IOW24 to drive a series of LEDs, using code i wrote that interface with Matlab.
I understand the IOW56 has a 1ms latency period as opposed to the much slower IOW24 and am interested
in upgrading.
Are the software side of things very similar? I.e., will a great deal of code change be required?
Note: all the code does is light the LED on/off after X ms. very simple.
cheers

The basic functionality is identical, of course you have to take care to adapt the data format, the 50 I/Os of IOW56 do not fit in the same report format as the 16 of the IOW24.

Cheers mate.
2 more questions
1) do you have an Application Note for iow56 connecting to 32/64 LEDs?
or does the same app note as iow24 applies? I am interested in the led power driver chips etc,
whether we can use the same ones.
2) While the reporting rate of the iow56 is 1ms, Windows XP have a much slower update rate (default usb 8ms)?
So the system will still be quantised at 8ms?
Or am I confused with this point?
thanks.

1. The same ap note applies. The IOW56 can drive a larger LED matrix, but the circuit is exactly the same as for IOW24/40.
2. No, Windows does poll at 1ms if the device defines this.

Mate, you are a legend.
