Both I2C using polling mode. I2C Clock Rate is set at 100K. UART0 is configure for display transmit process. After reset software will run the following steps: - First, the master transmit to slave a number of data bytes - Then, the master receive a number of data bytes from slave. - Finally, the master send two bytes to slave, send repeat start immediately and receive from slave a number of data byte. @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) i2c_master_slave_int_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 I2C connection: For I2C0: - SDA -> P0.27 - SCL -> P0.28 For I2C2: - SDA -> P0.10 - SCL -> P0.11 SDA pin of I2C master connects to SDA pin of I2C slave peripheral SCL pin of I2C master connects to SCL pin of I2C slave peripheral 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 I2C peripheral for master and slave by setting 'USEDI2CDEV_M' and 'USEDI2CDEV_S' - 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, and see the result in UART display tool. (Pls see "LPC17xx Example Description" document - chapter "Examples > I2C > Master_Slave_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
