The common library include startup file, standard definition andheader files, processor specific setup module, generic interrupt related APIs, timer routine, and scatter loading file. The peripheral directories include, GPIO, PWM, Real-time clock, timer, SPI, SSP, I2C, Watchdog timer, UART, external interrupt, ADC, DAC, etc.The development environment is Keil's, an ARM company now, uVision 3.xand ULINK ICE. The target board is Keil's MCB214x with a Philips's LPC214x MCU on it.Some external components, such as I2C temperature, SPI serial EEPROM, will be required to add on the board in order to complete the test below.
