主要针对ARM STM32F103RBT6 实现ADC转换，对生理信息进行采集，将微弱生理信号转换为数字信号。-Mainly for ARM STM32F103RBT6 AD converter has been verified through, small batch production.

随机共振来检测信号，检测的频率范围广，效果明显，适合检测微弱信号- Random resonance to detect the signal, the frequency range is wide, the effect is obvious, is suitable for the detection of weak signal
