+@Example description:
+	Purpose:
+		This example describes how to use ADC conversion in burst mode with single or multiple input.
+		This example also describes how to inject an ADC conversion channel while the others are running.
+	Process:
+		Because the potentiometer on different board connect to different ADC channel, so we have to configure correct 
+		ADC channel on each board respectively. In this case, 
+			- If using MCB1700 board: ADC is configured to convert signal on channel 2
+			- If using IAR-LPC1768-KS board: ADC is configured to convert signal on channel 5
+		The ADC conversion rate is 200KHz. A fully A fully accurate conversion requires 65 of these clocks. 
+		So ADC clock = 200KHz * 65 = 13MHz.
+		Note that maximum ADC clock input is 13MHz.  
+		
+		Burst ADC will repeatedly sample-convert the voltage on ADC0.x pin(s) then update the channel data register(s).
+		So we just need to read the ADC channel data register(s) and display the value via UART0. 
+		
+		Turn potentiometer to change ADC signal input.
+		
+		Only in burst mode, ADC can sample multiple channels, then we can inject by configuring this mode.
+		This example uses GPIO interrupt on P2.10 to trigger the injection, and uses P1.28 to toggle the LED
+		indicating that an ADC channel has just been injected or removed.

+
+@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: ON
+				- Remain jumpers: OFF
+
+			IAR LPC1768 KickStart vers.A
+				These jumpers must be configured as following:
+				- PWR_SEL: depend on power source
+				- DBG_EN : ON
+				- Remain jumpers: OFF
+				
+		ADC configure:
+			*For multiple inputs:
+				- The ADCx sample pin must not left floating, otherwise,
+				the readout value of these pins will same as the value 
+				of the pin which connected to a real voltage.
+				- This example uses an addition ADCx pin: AD0.3 (P0.26).
+				Make sure the SPK jumper is OFF.
+				- Try to make an external 10K, 3 pins vari-resistor,
+				1 terminal connects to 3.3V or Vrefp, the other connects to GND,
+				and the rest (middle pin) connects to P0.26 
+			*For injection test:
+				- LED jumper need to be ON to blinking LED P1.28.					
+				
+	Serial display configuration: (e.g: TeraTerm, Hyperterminal, Flash Magic...) 
+		– 115200bps 
+		– 8 data bit 
+		– No parity 
+		– 1 stop bit 
+		– No flow control 
+	
+	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: Choose correct working board by uncomment correct defined board in adc_burst_test.c file
+			+ If using MCB1700 board, uncomment "#define MCB_LPC_1768"
+				If test multiple input, then uncomment "#define MCB_LPC_1768_ADC_BURST_MULTI"
+				If test injection, then uncomment:
+					+ "#define MCB_LPC_1768_ADC_BURST_MULTI"
+					+ "#define MCB_LPC17XX_ADC_INJECT_TEST"
+			+ If using IAR-LPC1768-KS board, uncomment "#define MCB_LPC_1768"
+			(Should not uncomment both symbols at the same time)
+		- Step 2: Build example.
+		- Step 3: Burn hex file into board (if run on ROM mode)
+		- Step 4: Connect UART0 on this board to COM port on your computer
+		- Step 5: Configure hardware and serial display as above instruction 
+		- Step 6: Run example, turn potetiometer and observe data on serial display
+				  *For injection test:
+				  	- Press the INT0 button (on MCB1700 board) to see the state of LED P1.28:
+				  		+ ON: ADC channel 3 has just been inserted.
+				  		+ OFF: ADC channel 3 has just been removed.
+				  	- Look at the PC's terminal application screen, associate with the state of LED P1.28:
+				  		+ ON: the ADC channel 3 value is continuosly updated.
+				  		+ OFF: the ADC channel 3 value is unchanged, keep its last updated value.
