Hello friends,
Im using 7 inches TFT module (800x480) with LPC1788 controller. This is the first time I'm using a TFT module. Somehow I have managed to get some theoretical idea about TFT. But I have confused with the use SDRAM with TFT module. Is SDRAM is optional or it is compulsory if we are using a TFT LCD especially 7 inches LCD? Can someone please help me regarding this issue?
But I couldn't find a formula to fing a value for DynamicRefresh Register For that you will have to read the datasheet of the SDRAM that you are using _very carefully_ and also refer to the timing diagrams that are given in the datasheet. The values may not be given to you directly as is in the datasheets. you will have to study the datasheet and figure them out. Depending upon the memory organization, the timings are to be configured. The timings are nearly same for the SDRAMs with same memory organization (even though the manufacturers may be different).
Thank you for all for your kind reply. I configured the SDRAM with LPC1788. Now I want to write and read data from SDRAM. I can find the procedure in the SDRAM datasheet for write and read operations. But I cannot find any buffers for that operations in the LPC1788 datasheet. Say for example if I want to set the mode register how do I transfer the value to the EMC address pins. Or can i use the GPIO registers for this purpose. Kindly someone guide me on this issue.....
