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, I2C, Watchdog timer, UART, external interrupt, CAN, Ethernet, USB HID,etc. The development environment is Keil's, an ARM company now, uVision MDK 3.85 or later, and ULINK2 ICE. The target boards are Keil's MCB1700 with a NXP's LPC17xx MCU on it. Please note that, the latest Keil MDK includes the startup file, the header files, and Cortex related API files for NVIC and Systick driver. These files are also included in our common library. They may be slight change between the revisions. If the users wish to use Keil MDK default setting, the compiler can also be set: Change "#include "lpc17xx.h" to "#include <lpc17xx.h> where should be located under C:\Keil\ARM\INC\NXP directory. This is also necessary if Keil releases the update of the header file. Many of the peripherals are similar to those in LPC23xx/LPC24xx, except NVIC handling, not all the software modules have been ported from LPC23xx/24xx to LPC17xx yet. e.g. once you are familiar with LPC23xx/24xx family MCU, you can use LPC23xx/24xx as the reference and port simple driver from LPC23xx to LPC17xx. Go to below website and check out the sample code bundle under "Support Doc." for more details. http://www.standardics.nxp.com/products/lpc2000/all/~LPC2364/#LPC2364 The project is created for both target option "FLASH" and "RAM". For "FLASH", the image code can be programmed into the flash and executed; for "RAM", 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 0x10000000(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. By default, the test program is for Keil MCB1700 board.
