Adam, I checked the spec it doesn't explain how to communicate with the display? Datasheet always should explain how to send data but in your case it is not. Pin outs are clear how to wire but reset ??? How did you figure out what to do? I was looking for display like this too.

Adam Davis Sent: Monday, October 06, 2008 6:54 AM To: Microcontroller discussion list - Public. Subject: [PIC] Parallel interface to LCD I'm using the PIC32 parallel module to talk to a Samsung LCD controller (S6D0144), and am unable to get them talking to each other. I'm hoping someone has some experience with either the PMP module, the samsung controller, or one of the family to help me get started. Display: http://www.newhavendisplay.com/index.cfm/page/ptype=product/product_id=5 24/category_id=240/home_id=165/mode=prod/prd524.htm I've run out of things to check, so any help would be appreciated. Right now I have the PMP setup as follows: #define PMP_CONTROL (PMP_ON | PMP_READ_WRITE_EN | PMP_CS2_CS1_OFF) #define PMP_MODE (PMP_IRQ_OFF | PMP_MODE_MASTER2) #define PMP_PORT (PMP_PEN_OFF ) #define PMP_INTR (PMP_INT_OFF) My first boneheaded move was hooking up the low 8 bits and then find out that 8 bit mode runs on the high 8 bits. Rather than ripping them up I connected the other 8 so I'm running 16 bits now. I'm manually controlling RS and CS at the moment (I'm slowly removing the PMP from the equation since I've never used it before and have little confidence that I've set it up correctly) -Adam -- Save Money * Save Oil * Save Lives * Save the Planet http://www.driveslowly.org -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist IMPORTANT NOTICE: This notice constitutes Proprietary Rights identification of this email including all attachments, which is property that is intended only for the use of the individual or entity to which it is addressed.
