ECG
基于单片机的ECG数据采集与预处理
本课题首先介绍了心电信号检测电路的设计，给出了心电信号采集电路具体的设计方法与部分实现电路。并采用了线性光电耦合器放大电路，对前置级运算放大电路及后置级放大电路进行光电隔离，有效地抑制了各种干扰。 其次，主要进行基于AT89C52低功耗MCU的便携式心电监护仪及其系统的研究。
根据人体心电信号的特征，设计性能优良的心电信号采集系统，选用低功耗8位单片机AT89C52和大容量Flash存储器对采集的心电信号进行记录、分析及处理(MCU-based ECG data acquisition and pre-treatment of the subject introduced first ECG detection circuit design, are given specific ECG acquisition circuit design method and some realization of the circuit. And the use of a linear optocoupler amplifier, the pre-amplifier circuit-level operations and post-class amplifier circuit for photoelectric isolation, effectively a variety of interference suppression. Secondly, AT89C52 mainly low-power MCU-based portable ECG monitor their systems. ECG in accordance with the characteristics of the human body, the design performance of the ECG acquisition system, selection of low-power 8-bit MCU AT89C52 and large-capacity Flash memory on the acquisition of the recorded ECG, analysis and processing)

单片机MC9S08AW60脉宽调制 TPM1CH3 LS2亮度控制 KBI SEG控制亮度等级 。本工程为定时器输出PWM波测试工程实例通过对PWM占空比的调节,实现小灯的渐亮的功能,当占空比为100％时再从0％逐渐增加.PWM的周期一定要足够的快,否则其输出电压的波动范围很大,且测不出一个稳定的电压值,这样通过就观察不到小灯渐亮效果. 另外,在改变PWM的周期和占空比之前和之后要分别禁止和使用。(MC9S08AW60 pulse width modulation TPM1CH3 LS2 brightness control KBI SEG brightness level. This project is an example of testing the output PWM wave of the timer. By adjusting the duty ratio of the PWM, the function of the small lamp gradually brightening is realized. When the duty ratio is 100%, the period of the small lamp gradually increases from 0%. The period of the PWM must be fast enough. Otherwise, the fluctuation range of the output voltage is large and a stable voltage value can not be measured, so the effect of the gradual brightening of the small lamp can not be observed. In addition, the period of the PWM is changed. Before and after duty cycle should be prohibited and used separately.)
