"""Data log: minimal

Record a motor's angle and the IMU's heading on the board for 5 s while the motor turns, then
save them to a CSV file on the board (/data/run1_<date>_<time>.csv once the console has set the
board's clock).

The Python of datalog_minimal.evnblocks: the blocks and this file are the same program (open the
blocks file under Examples to see it as blocks).

Needs: a motor on port 1, free to turn; an EVN IMU module on I2C port 1, kept still
