1. STM32输出比较(Output Compare)功能的基本概念 STM32的输出比较(Output Compare)功能是一种利用定时器(TIM)模块,通过比较定时器的计数器(CNT)与捕获/比较寄存器(CCR)的值,来控制输出引脚的电平状态的功能。这种功能常用于实现精确的时间控制和特定频率、占空比的脉冲宽度调制(PWM)信号输出。例如,当定时器的计数器...
TIM_OC1PreloadConfig(TIM2, TIM_OCPreload_Disable); TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_Pulse = CCR2_Val; //这个是将CCR2_Val 的值送到TMI2_CCR2 中 TIM_OC2Init(TIM2, &TIM_OCInitStructure); TIM_OC2PreloadConfig(TIM2, TIM_OCPreload_Di...
在库函数中,修改 TIM1_CCR1 占空比的函数是: void TIM_SetCompare1(TIM_TypeDef* TIMx, uint16_t Compare1); 理所当然,对于其他通道,分别有一个函数名字,函数格式为 TIM_SetComparex(x=1,2,3,4)。 通过以上 6 个步骤,我们就可以控制 TIM1 的 CH1 输出 PWM 波了。 4.实例学习 实现:通过 TIM1_CH1...

Thereafter, 250 ml of 10% dextran were infused over 15 min to compare the effects of a preload-dependent increase in CO on IDVG measurements to the effects of the pharmacological modification of CO. Data were expressed as the mean 卤 SD. Statistical analysis was performed with repeated ...
the risk-benefit ratio of using pulmonary artery occlusion pressure (PAOP) as a measure of cardiac preload and recent studies have suggested a lack of benefit in some patient groups using the PAC [2]72-[4]. Recently, in a cohort of patients undergoing major non-cardiac surgery, it was ...

One-way Analysis of Variance (ANOVA) was used to compare cardiac output, heart rate and stroke volume at 24 h between the control, mild HIE and moderate HIE groups. If statistically significant differences were found, post-hoc pairwise comparisons were performed using Tukey’s Honestly Signific...
