turbinenreiter / error_propagation
Last active December 18, 2015 13:09
A small script to show the error propagation of simple integration.
import numpy as np
from scipy import integrate as i
from pylab import *
t = np.arange(0,100,1)
acc = np.empty(100); acc.fill(10)
acc_error = acc + 1
velo = i.cumtrapz(acc, t)
velo_error = i.cumtrapz(acc_error, t)
t = t[0:99]

This Arduino-sketch reads sensor data from the MPU6050 and stores it in the EEPROM.

#include <MPU6050.h>
#include <I2Cdev.h>

turbinenreiter / read_EEPROM
Created June 15, 2013 14:34
This Arduino-sketch reads data from the EEPROM and prints it to the Serial Monitor.
#include <EEPROM.h>
int m = 0;
int n = 0;
// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
