@Example description:
	Purpose:
		This example describes how to use SPI to read SD card's CID register 
	Process:
		SPI configuration:
			- CPHA = 0: data is sampled on the first clock edge of SCK.
			- CPOL = 0: SCK is active high
			- Clock rate = 1MHz
			- LSBF = 0: SPI data is transferred MSB first 
			- BITS = 8: 8 bits per transfer
			- MSTR = 1: SPI operates in Master mode
			1)Look for SD card connected or not, if yes then
			2)Configure SD card in SPI mode, then start SD card's internal
			initialization process.
			3)Read SD card's CID register then decode and display out via UART0

	lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example 
	makefile: Example's makefile (to build with GNU toolchain)
	spi_sdcard.c: Main program

@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
				- 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:
	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) 
		- Step 3: Connect UART0 on board to COM port on your computer
		- Step 4: Run example
				+ Plug in the SD card.
				+ Look at the PC terminal screen to see the information of SD card.
