Close Proteus completely. Navigate to your software installation path:

Which (Arduino, PIC, ESP32) are you pairing with the sensor? Share public link

These files allow you to search for the MAX30100 in the component picker and place its schematic symbol onto your workspace.

Check this box if you only want to use the sensor for PCB layout routing.

If you had Proteus open during the file transfer, close it completely. Restart the software as an Administrator (Right-click icon -> ) to ensure the software indexes the newly added database files. How to Fix Common MAX30100 Simulation Errors

By following the steps, you can avoid the headache of broken simulations. Make sure to download from a reliable source and paste the files into the correct LIBRARY directory. If you'd like, I can:

What (Arduino Uno, ESP32, PIC) are you trying to connect to the sensor?

The you are using (e.g., Arduino Uno, ESP32, PIC)

下面是一些可靠的寻找途径：

#include #include "MAX30100_PulseOximeter.h" #define REPORTING_PERIOD_MS 1000 PulseOximeter pox; uint32_t tsLastReport = 0; void onBeatDetected() Serial.println("Beat!"); void setup() Serial.begin(9600); if (!pox.begin()) Serial.println("FAILED"); for(;;); else Serial.println("SUCCESS"); pox.setOnBeatDetectedCallback(onBeatDetected); void loop() pox.update(); // Keeps the sensor reading alive // Strict non-blocking timer to prevent Proteus logic simulation errors if (millis() - tsLastReport > REPORTING_PERIOD_MS) Serial.print("Heart rate:"); Serial.print(pox.getHeartRate()); Serial.print("bpm / SpO2:"); Serial.print(pox.getSpO2()); Serial.println("%"); tsLastReport = millis(); Use code with caution.
