2018-06-08Prevent freezing USB during high frequency PulseIn.Scott Shawcroft
We now track the last time the background task ran and bail on the PulseIn if it starves the background work. In practice, this happens after the numbers from pulsein are no longer accurate. This also adjusts interrupt priorities so most are the lowest level except for the tick and USB interrupts. Fixes #516 and #876

2018-06-01Use the external crystal on SAMD21 again.Scott Shawcroft
Also, re-enable calibration storage for CircuitPlayground Express. Tested with a 500hz PWMOut on Metro M0 with Saleae: * with crystal 500hz * with usb 500hz +- 0.1hz * without either 487hz += 0.1hz SAMD51 is skipped due to DFLL errata and the fact it defaults to a factory calibrated 48mhz that works fine for USB. Fixes #648
