CCS有两种工作模式，即
软件仿真器模式：可以脱离DSP芯片，在PC机上模拟DSP的指令集和工作机制，主要用于前期算法实现和调试。
硬件在线编程模式：可以实时运行在DSP芯片上,与硬件开发板相结合在线编程和调试应用程序。
CCS的开发系统主要由以下组件构成： ① TMS320C54x集成代码产生工具； ② CCS集成开发环境；
③ DSP/BIOS实时内核插件及其应用程序接口API； ④ 实时数据交换的RTDX插件以及相应的程序接口API； ⑤ 由TI公司以外的第三方提供的各种应用模块插件。
CCS的功能十分强大，它集成了代码的编辑、编译、链接和调试等诸多功能，而且支持C/C++和汇编的混合编程。

4.3 软件分步配置:
4.3.1 配置ADC12：
F5529内部ADC为8位12通道模数转换器。实验中将P6.4作为模拟 信号的输入端口。时钟源为MCLK的3分频。
ADC12CTL0 = ADC12SHT02 + ADC12ON; // Sampling time, ADC12 on ADC12CTL1 |= ADC12SSEL0 + ADC12DIV2;
ADC12IE = 0x01; // Enable interrupt ADC12CTL0 |= ADC12ENC;
P6SEL |= 0x10; // P6.4 ADC option select
//ADC12SSEL 0:mclk 1:smclk
ADC12CTL1 |= ADC12SHP; // Use sampling timer ,0 clock
4.3.2 配置LCD1602：
采用F5529内置的点阵屏，相关详细配置参见F5529官方“HAL_Dogs102x6.c”
