Data collection + heart rate detector based on STM32 (schematic diagram, PCB, program source code, etc.).zip

This design is based on NUCLEO_F411RE as the control core, using the analog-to-digital converter inside the chip to collect external analog signals, and display the collected data with the cooperation of the TFT LCD screen. In order to facilitate visual analysis, the collected data is also drawn into a waveform graph. In order to verify its design function, a heart rate sensor is specially configured to obtain the heart rate signal. It has been actually verified that it can meet the basic requirements of the design during the acquisition process, and provides corresponding support for the generation of waveform image files. In addition, with the plug-in serial communication module, the collected data can be uploaded for deeper data analysis and processing.
