Read from the selected data file any three variables in the data, and will be read by data according to the format write self-built TXT file, at the same time please students in calculating the data points, three points average filter, limiter, the most value and its time points, the mean, variance, standard deviation of this 7 kinds of data processing method, choose two data processing methods to extract the data is analyzed, and the results show that on the screen (the most value and its time point, the mean, variance, standard deviation need 4 methods) and file,

Data file has the following names to choose from:
Will choose data: time_boot_ms
Choose two: roll, pitch, yaw, rollspeed, pitchspeed, yawspeed, servo1_raw, servo2_raw, servo3_raw, servo4_raw, chan1_raw, chan2_raw, chan3_raw, chan4_raw, chan5_raw, chan1_scaled, chan2_scaled, chan3_scaled, chan4_scaled, chan5_scaled, press_abs, press_diff,
