Scott Shawcroft	7ad2e6ace3	Add stack validity check and raise an error when it happens. The backtrace cannot be given because it relies on the validity of the qstr data structures on the heap which may have been corrupted. In fact, it still can crash hard when the bytecode itself is overwritten. To fix, we'd need a way to skip gathering the backtrace completely. This also increases the default stack size on M4s so it can accomodate the stack needed by ASF4s nvm API.	4 years ago
Scott Shawcroft	2fbab8067a	Prevent freezing USB during high frequency PulseIn. 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	5 years ago
