超简单断电复原3档亮度调光程序,每次开机都是低亮，不晃眼 低亮不是使用Pwm，而是使用电阻漏一部分电流给LED，超省电，无频闪，亮度随便调 源程序是东成的-3 super simple file recovery power brightness dimming process, each boot are low-light, non-dazzling light rather than the use of low-Pwm, but part of the use of resist

本代码用于眼电信号采集，采用电极传感器，对接受的信号进行放大，采集，处理，并提取眼电信息-This CODE IS USED FOR EYE information accqusition. so this we can distinguish illness from the health person .

STM32通过SPI通信控制ADC采集脑电、眼电、心电数据，并将得到的数据通过串口与蓝牙通信后将其发送至PC端进行处理(STM32 collects the data of EEG, eye and ECG through the SPI communication control ADC, and sends the obtained data to the PC side after communication through the serial port.)
