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?
That would depend on the refresh period of the SDRAM you have chosen, but not mentioned. This would perhaps be 8 or 16 ms, and the controller would likely need this period expressed in it's clock cycles?
