Hi
I am interfacing LPC2148 ARM7 with LCD controller S1D13781 but i am using 8 bit direct mode as specified in LCD controller Datasheet and send all configure bits to registers but finall y i am not able to generate HS and VS
if any one use S1D13781…

Can someone point me to a UART example and a USB virtual comm port example please ?
