@Example description:
	Purpose:
		This example describes how to use ADC conversion in interrupt mode.
	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.  
		
		ADC will generate interrupt at the end of each conversion. ADC service routine will be invoked 
		to check ADC status, if "DONE bit" is set, ADC converted data will be stored in "adc_value".
		ADC interrupt is disabled and re-enabled for the next conversion.
		ADC converted data are displayed via UART0.
		
		Turn potentiometer to change ADC signal input.

@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
				
	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_interrupt_test.c file
			+ If using MCB1700 board, uncomment "#define MCB_LPC_1768"
			+ 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
		
		(Pls see "LPC17xx Example Description" document - chapter "Examples > ADC > INTERRUPT"
		for more details)
		
@Tip:
	- Open \EWARM\*.eww project file to run example on IAR
	- Open \RVMDK\*.uvproj project file to run example on Keil
