The sample software includes, common library, peripheral APIs, and test modules for the APIs. The common library include startup file, standard definition and header 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.x and 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.
