DC motor on I2C Motor Driver(L298): PWM is 25Hz and can’t be changed

Hi Seraphina,
I made 2 new pull request for V1.05 library and 105 firmware on:

This is new firmware and library for grove I2C motor driver (L298).
News functionalities:

  • Get firmware version: very useful when you have a lot of cards with mixed version.
  • Set timeout and get timed out: when activated, the motor stops if no communication.after a specified time. Much more safe: with older version, the motor never stop if you reset your Arduino device!
    Can you ask to merge on github.
