Pattern Generator - Digital Discovery

[kevin vannorsdel]

The SDK document says this:

The initial values, for divider and counter, specify the initially loaded values, initial delay, when entering in Running
state. The Divider specifies the clock division. This rate will be the custom sample frequency and step for the
counter. When entering Running state, the initial value specified with FDwfDigitalOutDividerInitSet is loaded.
When this expires, the value specified by FDwfDigitalOutDividerSet will be loaded upon each expiration.

The block diagram also shows the word "Expire" in a few places.   

When do expirations happen?   In other words...  when does the INITIAL DIVIDER transition to the Other DIVIDER... ?   

 

Thanks!!!

Hi @kevin vannorsdel

It counts down, after reaching zero it loads the specified divider value.

Thanks for the response @attila,

I am trying to understand how many bits wide the divider and the counter are.   Where can I find that out?   Thanks!

Hi @kevin vannorsdel

Currently, for every device the divider is 31 and counter 15bit, FDwfDigitalOutDividerInfo FDwfDigitalOutCounterInfo
