Process: This example uses two SSP peripherals in TI frame format, one is set as master mode and the other is set as slave mode. SSP master/slave configuration: - CPHA = 0: data is sampled on the first clock edge of SCK. - CPOL = 0: SCK is active high - Clock rate = 1MHz - DSS = 8: 8 bits per transfer - MSTR = 0/1: SSP operates in Slave/Master mode - FRF= 1: MicroWire Frame format After initialize buffer, SPI master will transfer/receive data to/from SSP slave in INTERRUPT mode. After transmittion completed, receive and transmit buffer will be compared, if they are not similar, the program will enter infinite loop and a error notice will be displayed. @Directory contents: \EWARM: includes EWARM (IAR) project and configuration files \Keil: includes RVMDK (Keil)project and configuration files lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example makefile: Example's makefile (to build with GNU toolchain) ti_test.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 IAR LPC1768 KickStart vers.A These jumpers must be configured as following: - PWR_SEL: depend on power source - DBG_EN : ON - Remain jumpers: OFF SSP Connection: - P0.15 <-> P0.7 : SCK - P0.16 <-> P0.6 : SSEL - P0.17 <-> P0.8 : MISO - P0.18 <-> P0.9 : MOSI 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: Build example. - Step 2: Burn hex file into board (if run on ROM mode) - 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 example, observe SSP transfer result on serial display (Pls see "LPC17xx Example Description" document - chapter "Examples > SSP > TI" for more details) @Tip: - Open \EWARM\*.eww project file to run example on IAR - Open \RVMDK\*.uvproj project file to run example on Keil
