1.快速安装pack包包。
接下来就是开发环境的搭建了，本来打算使用IAR，无奈可能IAR版本太低，没找到LPC824这个型号，只好用keil了，我是用的mdk5.在网上下载了MDK5.18，下面有下载地址。

安装好后需要加载pack包，使用的是Keil.LPC800_DFP.1.3.0.pack，一般安装完成后会自动跳出加载pack包的界面，如果没有跳出，需要到安装目录下KeilUV4中找到PackInstaller.exe来进行加载，加载方式很简单.

以前很傻，mck官网下载对应的pack包，再双击解压安装，太麻烦！

2.注意，源代码中名字太长，路径不能有空格，否则keil编译器打开后报错！

分享一下模拟SPI的LCD驱动吧：摸索了一下如何取模：给大家分享如下：免得走弯路哦：
PCTolCD2002 @ 阴码逆向列行式
取模软件下载：http://www.pc6.com/softview/SoftView_16031.html

驱动代码如下：

//#include "chip.h"
//#include "board.h"
#include "SGX_G12864.h"
//#include "LPC11U6x_gpio.h"
//void Chip_GPIO_SetPinOutHigh(LPC_GPIO_T *pGPIO, uint8_t port, uint8_t pin);
