航顺的库。。
目前是 HK32F030Mxx_ExampleV1.0.5
PWM部分的demo还没做好,这里可以参照STM32F030的搞进去
这里输出 125K 定时器 就是 8us了

Note: SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f0xx.c file. Each time the core clock (HCLK) changes, user had to call SystemCoreClockUpdate() function to update SystemCoreClock variable value. Otherwise, any configuration based on this variable will be incorrect. ----------------------------------------------------------------------- */ /* Compute the prescaler value */ // PrescalerValue = (uint16_t) ((SystemCoreClock ) / 32000000) - 1;//配置频率为32M PrescalerValue = 32-1; /* 和下面设置预分频一样 */ /* Time base configuration */ TIM_TimeBaseStructure.TIM_Period = 8-1 ; /* 自动重装 数值*/ TIM_TimeBaseStructure.TIM_Prescaler = 0; /* 预分频 */ TIM_TimeBaseStructure.TIM_ClockDivision = 0; /* 不分频 */ TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure); /* Prescaler configuration */ /* 先配好ARR ,再设置预分频,PSC有预重装功能只能等更新事件来弄,不像ARR CRR立即更新重载 */ TIM_PrescalerConfig(TIM2, PrescalerValue, TIM_PSCReloadMode_Immediate);//每次UPdate重新初始化计数器 /*选择编码器模式1,根据TIFP1的电平,计数器在TI2FP2的边沿上下计数*/ // TIM_EncoderInterfaceConfig(TIM2, TIM_EncoderMode_TI1, TIM_ICPolarity_Rising, TIM_ICPolarity_Rising); /* TIM Interrupts enable */ TIM_ITConfig(TIM2, TIM_IT_Update, ENABLE); /* TIM3 enable counter */ TIM_Cmd(TIM2, ENABLE); /* Enable the TIM2 gloabal Interrupt */ NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn; NVIC_InitStructure.NVIC_IRQChannelPriority = 0; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); TIM_OCInitTypeDef TIM_OCInitStructure; /* 频道1,2,3,4的PWM 模式设置 */ /* PWM1 Mode configuration: Channel1 */ TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1; //PWM模式 TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low; TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_High; TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set; TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset; // TIM_OCInitStructure.TIM_Pulse = 500;//使能频道1配置 // TIM_OC1Init(TIM1, &TIM_OCInitStructure); /* 通道1 */ TIM_OCInitStructure.TIM_Pulse = 4;//使能频道2配置 TIM_OC1Init(TIM2, &TIM_OCInitStructure); /* 通道2 */ TIM_OCInitStructure.TIM_Pulse = 4;//使能频道2配置 TIM_OC2Init(TIM2, &TIM_OCInitStructure); /* TIM1 主输出使能 */ TIM_CtrlPWMOutputs(TIM2, ENABLE); } /*配置IO翻转*/ void GPIO_TogglePin(GPIO_TypeDef *GPIOx, uint16_t GPIO_Pin) { /* Check the parameters */ assert_param(IS_GPIO_PIN(GPIO_Pin)); GPIOx->ODR ^= GPIO_Pin; } #ifdef USE_FULL_ASSERT /** * @brief Reports the name of the source file and the source line number * where the assert_param error has occurred. * @param file: pointer to the source file name * @param line: assert_param error line source number * @retval None */ void assert_failed(uint8_t* file, uint32_t line) { /* User can add his own implementation to report the file name and line number, tex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */ } #endif /* USE_FULL_ASSERT */
