Process: SSP 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 = 1: SSP operates in Master mode - FRF= 0: SPI Frame format First, SSP send commands to reset, config direction SC16IS740 chip in interrupt mode. Start to use SSP polling mode to handle SC16IS740 board. On serial display: - Press 'r' to print menu - Press '1': send 0x00 value to IOStat register to turn on 8 LEDs on SC16IS740 board. - Press '2': send 0xFF value to IOStat register to turn off 8 LEDs on SC16IS740 board. (Pls see two pdf file at SPI\sc16is750_int: - SC16IS740_750_760_6.pdf - schematics.sc16is750.demo.board.pdf for more information about SC16IS740 board) @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) sc16is750_int.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 SC16IS750 board: These jumpers must be configured as following: - JP2: 2-3 (SPI) - JP16: 2-3 (hard reset) - Remain jumper: OFF SPI connection: - P0.15 - SCK on eval board connects to SCLK on SC16IS750 board - P0.16 - SSEL on eval board connects to /CS on SC16IS750 board (used as GPIO) - P0.17 - MISO on eval board connects to MISO on SC16IS750 board - P0.18 - MOSI on eval board connects to MOSI on SC16IS750 board Common power source 3.3V and ground must be connected together between two board. 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 5: Connect UART0 on board to COM port on your computer - Step 6: Configure hardware, connect this board with SC16IS750 board as above instruction - Step 7: Configure serial display as above instruction - Step 8: Run example and handle SSP transfer via serial display + Press '1' to turn on 8 LEDs on SC16IS750 board + Press '2' to turn off 8 LEDs on SC16IS750 board (Pls see "LPC17xx Example Description" document - chapter "Examples > SSP > sc16is750_int" for more details) @Tip: - Open \EWARM\*.eww project file to run example on IAR - Open \RVMDK\*.uvproj project file to run example on Keil
