Bradley Scott	260378e774	STM32: Fix 32-bit us ticker interrupt scheduling ... For STM32 targets using a 32-bit timer for the microsecond ticker, the driver did not properly handle timestamps that are in the past. It would just blindly set the compare register to the requested timestamp, resulting in the interrupt being serviced up to 4295 seconds late (i.e. after the 32-bit timer counts all the way around to hit the timestamp again). This problem can easily be reproduced by creating a Timeout object then calling the timeout's attach_us() member function to attach a callback with a timeout of 0 us. The callback will not get called for over 2147 seconds, and possibly up to 4295 seconds late if no other microsecond ticker events are getting scheduled in the meantime. Now, after the compare register has been set, the timestamp is checked against the current time to see if the timestamp is in the past, and if so, the compare event is manually set. NOTE: By checking if the timestamp is in the past after configuring the capture register, we ensure proper handling in the case where the timer updates past the timestamp while setting the capture register.	2017-06-01 12:52:03 -04:00
