Arduino-Entropy-Library

An attempt to provide a source of randomness to Arduino based devices. This library uses:

• The hardware TrueRNG of the SAM3X8E when being compiled on the Arduino Due and friends;
• The presumably random discrepancies between the main MCU clock crystal (running at 48MHz for the Arduino Zero/MKR1000) and the low power 32KHz crystal as a source of randomness.
