* fix(timer): Output Compare issue #74Uri Shaked2020-12-212-10/+28
| | | | | | output compare doesn't work when the OCR register (OCRnA/OCRnB) equals to 0 fix #74
* fix(timer): TOV flag does not update correctly #75Uri Shaked2020-12-202-20/+56
| | | | fix #75
* fix(timer): OCR values should be buffered #76Uri Shaked2020-12-202-11/+125
| | | | fix #76
* perf(cpu): speed up event systemUri Shaked2020-12-122-18/+59
| | | | ditch `array.sort()` and instead manually keep the array sorted when we insert a new item.
* test(cpu): fix implicit any errorUri Shaked2020-12-121-3/+5
|
* fix(cpu): event system issueUri Shaked2020-12-122-2/+63
| | | | | | | `updateClockEvent()` and `clearClockEvent()` would sometimes mess up the list of events. This could cause unexpected behavior when you have multiple timers running. Also added regression tests for these methods.
* fix(timer): Incorrect count when stopping a timerUri Shaked2020-12-122-18/+41
| | | | fix #72
* perf!: centeral timekeepingUri Shaked2020-12-0912-221/+222
| | | | | | | | | This should improve performance, especially when running simulations with multiple peripherals. For instance, the demo project now runs at ~322%, up from ~185% in AVR8js 0.13.1. BREAKING CHANGE: `tick()` methods were removed from individual peripherals. You now need to call `cpu.tick()` instead.
