Hallo As I read the LPC2478 documentation, its not possible to use on USB port as OTG and interface to a LCD (with 16 bit color) at the same time. OTG uses P1.27, P1.28 and P1.29. But they are used for LCD signals as well. Do I understand the LPC2478 dosumentation right? I only whant to use one USB port. /Thomas ------------------------------------

Dear ARMieessss.. thanks for your replies , but my problem is I want to connect a 5V interface in traditional way that is 8 data lines and 3 control lines with LPC2214, now LPC2214 datasheet is saying that all GPIOs are 5V tolerant so I think I can connect the LCD with Pull Ups on GPIO pins or can I directly connect the 5V LCD with the port pins.
