    emWin Graphics library drivers?


      I downloaded your PSOC 5 object library for Segger's emWin Graphics library.  However, the only driver I see is the GUIDRV_CompactColor_16.c.  I am using the Sitronix ST7529 LCD controller.  Does Cypress happen to have this LCD driver?  If not, do I need to go to Segger direct?

          I've been poking around with this myself (http://www.cypress.com/?app=forum&id=2492&rID=58742).


          From what I understand, and some one please correct me, is there are two drivers provided by Cypress. One runs on the controller-less graphics peripheral, and the other is the GUIDRV_CompactColor_16 driver. Both are configured to run in a parallel bus setup.


          According to Segger documentation, the GUIDRV_CompactColor_16 runs the following display controllers:

          I understand that from Segger you can acquire other drivers. Maybe get a copy of GUIDRV_Template from them and you/we can customize? They most likely have already written exactly what you need though.

             Oh, since you have a sitronix with similar product number, maybe the compact color driver can be altered with some defines -- I noticed somewhere in the code there were defines that indicated register locations and commands. Of course I forget the exact spot
