1、TIM_ClockConfigTypeDef是对TIM依赖的时钟进行配置,默认情况下TIM 挂在APB时钟上,若需要使用外部时钟,可对成员ClockSource进行配置 2、TIM_MasterConfigTypeDef是当需要使用到定时器的级联时内部输出通道及SlaveMode的配置,默认都是否 TIM_HandleTypeDef htim3;voidMX_TIM3_Init(void) { TIM_ClockConfigTypeDef sClo...
TIM_ClockConfigTypeDef sClockSourceConfig = {0}; sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL; /* 选择内部时钟 */ HAL_TIM_ConfigClockSource(&timx_handle, &sClockSourceConfig); 后面的定时器初始化凡是用到内部时钟我们都没有去进行初始化,系统默认即可。

然后是 MX_TIM2_Init 函数,里面包含了时基单元的基本配置(和标准库基本长得一样),以及时钟源的选择(那个 INTERNAL): // 后面主从模式是 DISABLE 的,只是代码生成了voidMX_TIM2_Init(void){TIM_ClockConfigTypeDefsClockSourceConfig={0};TIM_MasterConfigTypeDefsMasterConfig={0};htim2.Instance=TIM2;htim2...
