篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了TI MSP430工程配置及2019年电赛A题编程示例（使用430 F5529）相关的知识，希望对你有一定的参考价值。
配置
第一步：右击工程，选择Options
第二步：在General Options的Target选项卡里选择对应的器件Device，这里是MSP430G2231
第三步：在Debugger里选择FET Debugger：
第四步： 检查FET Debugger里的设置是否正确，这里是Texas Instrument USB-IF采用Automatic方式
这里选择Automatic与Automatic selection，当用串口会自动连接上串口。
第五步：编译程序，下载验证
