Image Writer / Mbed 2 deprecated serial_dimmer

Serial communication test.

Dependencies:   mbed

This program is test of LPC1114 serial communication.

When you use Mac, it is as follows.

1)Run the Terminal.app.

2)ls /dev/tty.usb*

When you use USB-Serial converter and RS232C level conveter, It is displayed with /dev/tty.usbserial-xxxxxxxxx.

When you use LPC1114FN28 mbed board from USB cable, It is displayed with /dev/tty.usbmodemfdxxxx.

3)Run the screen command.

screen /dev/tty.usbXXXXXXXX.

4)Press 'u' to turn LED1 brightness up,'d' to turn it down.

Case1:LPC1114FN28 mbed board.
