@Example description:
	Purpose:
		This example, together with receive example, describes how to use UART in IrDA mode
	Process:
		UART0/UART1 configuration:
			– 9600bps 
			– 8 data bit 
			– No parity 
			– 1 stop bit 
			– No flow control 
			- Receive and transmit enable
		UART3 configuration:
			– 9600bps 
			– 8 data bit 
			– No parity 
			– 1 stop bit 
			– No flow control 
			- Enable IrDA mode
			- Transmit enable
		
		UART will print welcome screen first, then:
			- Press ESC to exit.
			- Press 'r' to print welcome screen menu again.
			- Press two hex digits (each digit is from 0..F/f, ex: 1f means 0x1F) to form a byte value for UART3 TXD to transmit.
			- Press other keys will take no effect.
					
		Note: If using this example to print with UART1, pls add conversion type (LPC_UART_TypeDef *)LPC_UART1
		because UART1 has different structure type
		Ex: UART_Send((LPC_UART_TypeDef *)LPC_UART1, menu1, sizeof(menu1), BLOCKING);

	makefile: Example's makefile (to build with GNU toolchain)

@How to run:
	Hardware configuration:		
		This example was tested on:
			Keil MCB1700 with LPC1768 vers.1
				These jumpers must be configured as following:
				- VDDIO: ON
				- VDDREGS: ON 
				- VBUS: ON
				- AD0.2: OFF
				- Remain jumpers: OFF
				
			Add in hardware: (1 infrared transmit led, 1 C1815 transistor, 1 33R, 1 150R)
					- An infrared transmit led with its anode connected to 3.3V, cathode connected
					to 33R resistor. The other end of this resistor connects to C1815 collector. C1815's emmitor connects to GND.
					- Use a wire to connect P0.25, AD0.2 jumper, with 150R resistor, the other end of this resistor connectd to C1815 base.
				
				
	Running mode:
		This example can run on RAM/ROM mode.
					
		Note: If want to burn hex file to board by using Flash Magic, these jumpers need
		to be connected:
			- MCB1700 with LPC1768 ver.1:
				+ RST: ON
				+ ISP: ON
			- IAR LPC1768 KickStart vers.A:
				+ RST_E: ON
				+ ISP_E: ON
		
		(Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with
		LPC1000CMSIS project" for more information)
	
	Step to run:
		- Step 1: Build example.
		- Step 2: Burn hex file into board (if run on ROM mode)
				  Also burn the receive example hex file to other board.
		- Step 3: Connect UART0 on this board to COM port on your computer
		- Step 4: Configure hardware and serial display as above instruction 
		- Step 5: Run both examples.
				  Point the transmit infrared led to the receive infrared led.
				  From PC's terminal application, type 2 hex digits to form a byte to transmit.
				  Observe the 8 leds bank of the receive board to compare with the transmit value.
