Hi!

I'm having a problem with connecting these two devices. So far I know I have to connect it through UART but I don't have a clue how. What sort of cable should I use? I looked through documentation of both devices, and I found UART0 and UART1 in my LPC and don't know the difference. The only thing that I know is that UART0 has 2 pins and UART1 has 9 pins, but I don;t know how to use it in practice. What should I take under consideration in UART interface while chosing the way to connect these two? Thanks in advance.
