Would need to be re-worked once #87 is merged. |

Related to #68, but that PR is for a different speed and has different conditions. |

Thank you for this even if it hasn't been merged! It's easy enough to change this in your own script by adding the same code: Which makes things on the Feather M0 boards pretty fast! |

Changed from the default I2C clock (100KHz ?) to 1MHz for SAMD Zero boards. Tested with an Adafruit Feather M0 Adalogger and an Adafruit FeatherWing OLED. I did try 3.4MHz but that speed didn't work.
