Here's an equivalent program written in Java that collects heart rate data from a chest strap at maximum sampling rate using the Garmin SDK:
import com.garmin.fit.*;
// Connect to the Garmin device
Device device = GarminDevice.getDevice();
// Start the heart rate monitor
device.hrmStart();
// Get the maximum sampling rate
int samplingRate = device.hrmGetSamplingRate();
// Collect the heart rate data
List<Integer> heartRateData = new ArrayList<>();
while (true) {
int heartRate = device.hrmGetHeartRate();
heartRateData.add(heartRate);
try {
Thread.sleep(1000 / samplingRate);
} catch (InterruptedException e) {
break;
}
}
// Stop the heart rate monitor
device.hrmStop();
// Save the collected data to a file
try (BufferedWriter writer = new BufferedWriter(new FileWriter("heart_rate_data.txt"))) {
for (int data : heartRateData) {
writer.write(Integer.toString(data));
writer.newLine();
}
} catch (IOException e) {
System.err.println("Error saving data to file: " + e.getMessage());
}
then "rewrite the above using Java"
