updated to fit new acceleration and time/millis
parents 37936beb 3526716a
# log the accelerometer values to a file, 1 per second
# log the accelerometer values to a .csv-file on the SD-card
f = open('motion.dat', 'w') # open the file for writing
import pyb
for i in range(60): # loop 60 times
time = pyb.time() # get the current time
accel = pyb.accel() # get the accelerometer data
accel = pyb.Accel() # create object of accelerometer
blue = pyb.LED(4) # create object of blue LED
# write time and x,y,z values to the file
f.write('{} {} {} {}\n'.format(time, accel[0], accel[1], accel[2]))
log = open('1:/log.csv', 'w') # open file to write data - 1:/ ist the SD-card, 0:/ the internal memory
blue.on() # turn on blue LED
pyb.delay(1000) # wait 1000 ms = 1 second
for i in range(100): # do 100 times (if the board is connected via USB, you can't write longer because the PC tries to open the filesystem which messes up your file.)
t = pyb.millis() # get time since reset
x, y, z = accel.filtered_xyz() # get acceleration data
log.write('{},{},{},{}\n'.format(t,x,y,z)) # write data to file
f.close() # close the file
log.close() # close file
blue.off() # turn off LED
