The Example 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. The peripheral directories include, ADC, DAC, DMA, GPIO, PWM, Real-time clock, timer, SPI, SSP, MCI, I2C, Watchdog timer, UART, external interrupt, CAN, Ethernet, USB Audio, USB HID, etc. The development environment is Keil's, an ARM company now, uVision 3.x and ULINK ICE. The target board is Keil's MCB2300 with a NXP's LPC23xx MCU on it. The project is created for both target option "MCB2300" and "MCB2300 Debug". For "MCB2300", the image code can be programmed into the flash and executed; for "MCB2300 Debug", the image code can be loaded into internal SRAM(IRAM) for easy debugging. The "RAM.ini" in each directory is a Keil uVision debugger script file, once the debugger starts, the code will be loaded to the IRAM first, then, "RAM.ini" will be executed and reset program counter(PC) to 0x40000000(IRAM starting address) that code will be executed from. 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.
