MPU6050 display raw data and fft from the reading get
from this code what is the problem that i faced because the fft not show
a = arduino;
imu = mpu6050(a);
xlabel(‘Count’);
ylabel(‘Acceleration (m/s^2)’);
title(‘Acceleration values from mpu6050 sensor (Z-axis only)’);
z_val = animatedline(‘Color’,’b’);
axis tight;
legend(‘Acceleration in Z-axis’);
stop_time = 100;
count = 1;
tic;
while(toc <= stop_time)
[accel] = readAcceleration(imu);
if ~isempty(accel)
addpoints(z_val,count,accel(:,3));
% Compute FFT of the Z-axis acceleration
fft_z = fft(accel(:,3));
n = length(fft_z);
freq = (0:n-1)*(100/stop_time)/n; % Assuming sampling rate based on stop_time
% Plot the FFT magnitude
subplot(2,1,2);
plot(freq, abs(fft_z));
xlabel(‘Frequency (Hz)’);
ylabel(‘Magnitude’);
title(‘FFT of Z-axis Acceleration’);
drawnow limitrate;
count = count + 1;
end
