2019-11-26Fix ePaper so it works after a GC.Scott Shawcroft
We weren't correctly collecting the start and stop sequences. As a result, the GC would free the space and allocate other info there. Thanks to JacobT on Discord for the bug report!
2019-11-18Supervisor: move most of systick to the supervisorJeff Epler
This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up
