UART Interrupt with Ring Buffers Example
========================================

Example Description
-------------------
The UART example shows how to use the UART in interrupt mode with transmit
and receive ring buffers.

To use the example, connect a serial cable to the board's RS232/UART port and
start a terminal program to monitor the port.  The terminal program on the host
PC should be setup for 115200-8-N-1.
Once the example is started, a brief message is sent to the terminal. Any data
received will be displayed on the terminal.

Special connection requirements
-------------------------------
Board [NXP_LPCXPRESSO_812]:

Board [NXP_812_MAX]:
Connect TX, RX and GND from J2 [Arduino Digital Header] to an FTDI Cable.
LPC812            FTDI cable
 GND: J1-4         black
 RX:  J2-8 (D0)    orange
 TX:  J2-7 (D1)    yellow
Do not connect a stock, unmodified LPC810-Max board the LPCXpresso base board.
The CMSIS-DAP debugger will halt.

Board [NXP_LPCXPRESSO_824]:
Connect the board to a base board. The output will appear at USB-mini port X3.
Make sure that the jumpers on J7 are configured correctly.
Or, connect TX, RX and GND from J2 [Arduino Digital Header] to an FTDI Cable.
LPC824            FTDI cable
 GND: J1-4         black
 RX:  J2-8 (D0)    orange
 TX:  J2-7 (D1)    yellow
