此代码是在LPC2138测试（512KB闪存）。
每个项目配置为使用512KB闪存；然而，由于
每个项目的规模将是最小的LPC213x／4x系列
这不应该引起任何问题。使用不同的微控制器可能需要
示例代码的更改。(This code was tested on the LPC2138 (512kb Flash).
Each project is configured to use the 512kb flash; however, since the
size of each project will fit in the smallest of the LPC213x/4x series
this should not cause any issues. Using a different MCU might require
a change in the sample code.)
