# Create a data log file in the project folder on the EV3 Brick.
|
|
# * By default, the file name contains the current date and time, for example:
|
|
# log_2020_02_13_10_07_44_431260.csv
|
|
# * You can optionally specify the titles of your data columns. For example,
|
|
# if you want to record the motor angles at a given time, you could do:
|
|
data = DataLog('time', 'angle')
|
|
|
|
# Initialize a motor and make it move
|
|
wheel = Motor(Port.B)
|
|
wheel.run(500)
|
|
|
|
# Start a stopwatch to measure elapsed time
|
|
watch = StopWatch()
|
|
|
|
# Log the time and the motor angle 10 times
|
|
for i in range(10):
|
|
# Read angle and time
|
|
angle = wheel.angle()
|
|
time = watch.time()
|
|
|
|
# Each time you use the log() method, a new line with data is added to
|
|
# the file. You can add as many values as you like.
|
|
# In this example, we save the current time and motor angle:
|
|
data.log(time, angle)
|
|
|
|
# Wait some time so the motor can move a bit
|
|
wait(100)
|
|
|
|
# You can now upload your file to your computer
