    Hi,

    I'm trying to do a tft lcd module with ARM processor. So I'm deciding which model to use now. I found that some MCU provide LCD controller module but some no. I wonder what LCD controller do. From what I know, TFT LCD pinout is controlled by IO pin. What if I directly connect my ARM processor to TFT LCD rather than putting a LCD controller in between?

    Thanks.

    the lpc2478fbd208 ARM is good for LCD's. You can connect the LCD directly to this MCU.

    While I use Microchip products it is typical to just connect the LCD direct to the IO pins. Just make sure they talk in the same voltages: don't mix a 3.3V device and a 5V device unless you're willing to out a level translator in between (which I did once and works fine).
