I've got a project include ESP32 and 3 sensors. But i don't know how to combine these code together. omg!!! Could you help me or guide me how to combine these 3 sketches:
1.
#include <Wire.h>
#include "MAX30100_PulseOximeter.h"
#define REPORTING_PERIOD_MS 1000
// Create a PulseOximeter object
PulseOximeter pox;
// Time at which the last beat occurred
uint32_t tsLastReport = 0;
// Callback routine is executed when a pulse is detected
void onBeatDetected() {
Serial.println(" Beat!");
}
void setup() {
Serial.begin(115200);
Serial.print("Initializing pulse oximeter..");
// Initialize sensor
if (!pox.begin()) {
Serial.println("FAILED");
for(;;);
} else {
Serial.println("SUCCESS");
}
// Configure sensor to use 7.6mA for LED drive
pox.setIRLedCurrent(MAX30100_LED_CURR_7_6MA);
// Register a callback routine
pox.setOnBeatDetectedCallback(onBeatDetected);
}
void loop() {
// Read from the sensor
pox.update();
// Grab the updated heart rate and SpO2 levels
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();
}
}
