stm32f030单片机的定时器,调试时无法暂停,如何处理?
查了下资料,可以通过芯片复位状态下 写DBGMCU->APB1FZ 寄存器实现。
但是实际中如何操作未知。
库函数存在 DBGMCU_APB1PeriphConfig() 函数,程序运行时调用不起作用。
/**
* @brief Configures APB1 peripheral behavior when the MCU is in Debug mode.
* @param DBGMCU_Periph: specifies the APB1 peripheral.
* This parameter can be any combination of the following values:
* @arg DBGMCU_TIM2_STOP: TIM2 counter stopped when Core is halted,
* not applicable for STM32F030 devices
* @arg DBGMCU_TIM3_STOP: TIM3 counter stopped when Core is halted
* @arg DBGMCU_TIM6_STOP: TIM6 counter stopped when Core is halted
* @arg DBGMCU_TIM7_STOP: TIM7 counter stopped when Core is halted,
* applicable only for STM32F072 devices
* @arg DBGMCU_TIM14_STOP: TIM14 counter stopped when Core is halted
* @arg DBGMCU_RTC_STOP: RTC Calendar and Wakeup counter stopped
* when Core is halted.
* @arg DBGMCU_WWDG_STOP: Debug WWDG stopped when Core is halted
* @arg DBGMCU_IWDG_STOP: Debug IWDG stopped when Core is halted
* @arg DBGMCU_I2C1_SMBUS_TIMEOUT: I2C1 SMBUS timeout mode stopped
* when Core is halted
* @arg DBGMCU_CAN1_STOP: Debug CAN1 stopped when Core is halted,
* applicable only for STM32F042 and STM32F072 devices
* @param NewState: new state of the specified APB1 peripheral in Debug mode.
* This parameter can be: ENABLE or DISABLE.
* @retval None
