基于stm32对ads1298进行读取，用于心电前端采集-Based on ads1298 stm32 read, front-end for ECG acquisition

本程序实现了LTDC液晶对ADC采集到的数据进行显示，并通过LCD分层显示心电波形，正弦波，方波，三角波等等。程序简单明了，几个函数就可以轻松应用STM32F429 Discovery的高级LTDC液晶分层显示功能(This program implements LTDC LCD to display data collected by ADC, and displays ECG waveform, sine wave, square wave, triangle wave and so on

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.)
