can I have non-sequential values in menu ring?

[bmishoe]

I am creating some menu rings that are meant to replace what was a hexadecimal numeric field.

The register definition itself is a longstanding thing within our FPGA, and out of my hands.  So let's say its a 2 bit field defined as follows:

b00: unused

b01: CRC-ON

b10: unused

b11: CRC-OFF

So I want my menu ring to only have the options CRC-ON and CRC-OFF, but so far the only way I see to do this is to also create the 2 unused fields, because I can't edit the values manually within the menu ring properties.  I don't want 2 'blank options' to show up on the menu ring.

I also tried the enum ring but it too wanted things sequential.  Do I need to use a different type of control, or do I need to add code that translates the value chosen in the menu ring to the actual value I want?

You should be able to only have the two options you want in the menu ring. Right-clicking on the ring control and choosing "Edit Items...", you should get a dialog with a table of Items and Values. If you deselect the checkbox for "Sequential values", you can then edit the values associated with those items.

haha, how in the world did I miss a box that says "sequential values"?  wow.

thank you.

You can even play with the display format to make that bitfield "Look Right:

Although it would be kind of nice if the item editor respected the choice and updated dynamically when the display format changes.  (It only bugs develoers- Users never see the page)
