CCDs and NVRAM

 
Edited

Learned a valuable less today.? I am using the Sony IP CCD modules for both TV and Receivers.? Apparently they are NVRAM hungry.? Each CCD allocates about 10KB of NVRAM.? I am just updating a program with 24 rooms and each room is mostly duplicated to make it easy to expand.? First time every that I got the warning that my program has exceeded the allotted NVRAM of a processor, PRO4 fyi.? Now to go back through and comment out the CCD's I don't need.
 

Well must be a hold over from 2 series in Simpl, crisis averted.? I checked the PRO4 and it actually has 3MB of NVRAM.??

SIMPL+ NVRAM allocation was introduced in CCD Disp Eth v1.14.
(F1 Revision History calls out "Added ability to page through more than 10 user attributes.")

SIMPL compiler calls out max NVRAM allocation for the program slot after adding 20-something CCD Disp Eth v1.14+ instances.
For now the workaround is to use CCD Disp Eth v1.13 or split the CCD Disp Eth v1.19 module instances into multiple program slots.

The Driver team is working to utilize SIMPL# (instead of SIMPL+) for holding the persistent data to correct this behavior.
I don't have an ETA for the module update that will accomplish this, but it is something we're tracking, and I'll update the thread when I know more.

BR 5812 = SIMPL - CCD Display Module - v1.14-1.19 allocating NVRAM and unable to compile when using multiple instances
?
BR 5812 solved noting SIMPL+ calls storing data have been removed from v2.x modules.
In removing that code, the programmer must now send the user attribute data in at the correct time - AFTER the driver has been loaded.
The proper sequence is: Load Driver -> Loaded_FB -> Set User Attributes (including "Send it In") -> Trigger Connect
?

Example SIMPL programs showing this logic will be posted to the SDK-CD page resources tab soon.

Can Crestron please figure out an appropriate spot for all the CCD SDK downloads?

The one that most people reference on the developer site still hosts v8, and secretly v14 has been added to a random product page? I've asked about a more recent public download of the CCD SDK for years. Where are all the versions v9 through v13 though, and how is anybody supposed to find out about this stuff?...

edit: And where are the release notes in the v14.0000.0008 download? It exists in the others. :/

I suspect the new SDK-CD product page is the new place to obtain the latest versions; the developer site's "Resources" section will probably point to that page in the future.

The SDK-CD Release Notes appear to be hosted online, available from the download page (similar to FW Release Notes).
