使用值指定default与省略LangVersion选项不同。 指定default会使用编译器支持的语言的最新版本,而不考虑目标框架。 例如,如果未指定 LangVersion,则通过 Visual Studio 版本 17.6 生成面向 .NET 6 的项目将使用 C# 10,但如果LangVersion 设置为default,则使用 C# 11。
2、观察SVPWM的PWM波形是对称的: 正好配置TIM1为中央对齐模式1,在上面代码的配置中,载波周期为15KHz,TIM_Period(ARR)=2400,CH1的TIM_Pulse(CCR)=800。采用的PWM1模式,即CNT小于CCR时,输出有效电平,大于CCR小于ARR时,输出无效电平,又配置CHx的有效电平为高电平,CHxN的有效电平为高电平,则可以得到下面的PWM波形:...
class S { public: S() = default; private: S(const S&) = default; }; void f(const S&); // pass S by reference int main() { S s; f(s); } 弃用属性化 ATL 代码支持(默认开启等级 1 (/W1)) 以前版本的编译器支持属性化 ATL 代码。 由于下一阶段将删除从Visual Studio 2008 开始的...
