After 5s, + the Watchdog timer times out, WDT interrupt sevice routine 'WDT_IRQHandler( )' will + be invoked to change 'wdt_flag'. The notice sentence will be display and LED begin blinky. + + Note that: dispaly data via UART will caused delay. + +@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) + wdt_interrupt_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 + - LED: 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: + RAM mode: This example can be run on RAM mode with debugger. + All files must be build to .elf file, this file will be loaded into RAM through a + debugger tool before running + ROM(FLASH)mode: This example can be run on ROM mode with debugger or standalone after burning. + All files in each example must be built to .hex file.
