MAT0.0(P1.28) toggle and timer will be reseted. + + Note that: print data via UART can cause delay when match time set is too small. + +@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) + timer_int_match.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 + + 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 and observe match interrupt notice on serial display + + On MCB1700 board: MAT0.0(P1.28) connect with LED P1.28, so you can observe MAT0.0 toggle via + LED P1.28 blinky process. + + On IAR board: MAT0.0 signal can be observed by oscilloscope or wire P1.28 pin with LED1(P1.25) + + (Pls see "LPC17xx Example Description" document - chapter "Examples > TIMER > Interrupt_Match" + for more details) + +@Tip: + - Open \EWARM\*.eww project file to run example on IAR + - Open \RVMDK\*.uvproj project file to run example on Keil \ No newline at end of file
