NI-8451 I2C High Speed mode

[Briton]

Hi

I'm trying to setup my NI-8451 to High Speed mode, but there must be something I don't understand.
I got this code, but clock rate is sticking to the default rate at 100KHz.

I'm able to shift between the standard mode rates.

thanks in advance

Read the specifications.  The fastest the USB-8451 can go is 250kHz using Fast Mode.  Fast Mode Plus and High Speed modes are not supported.  You will need to use the USB-8452 if you need High Speed mode.

As an aside, it looks like you could make your diagram A LOT simpler by using the basic API and a property node instead of chaining up that many script VIs.

Thanks Crossrulz

I don't know what has been wrong, except that I wrote high Speed mode instead of Fast mode.
I have set i to 200KHz before and measured with scope and I couldn't get it over 100KHz.
Now i have deleted the Case structure and used the normal Clock rate script and then i works
