* feat(usart): add configuration change eventUri Shaked2021-07-152-3/+95
| | | | also add `txEnable` and `rxEnable` properties
* fix(timer): only set ICR hook for 16-bit timersUri Shaked2021-07-071-3/+3
| | | | The ICR (Input Capture Register) only exists for 16-bit timers.
* feat(gpio): external interrupt/PCINT support (#82)Uri Shaked2021-07-074-18/+459
| | | close #70, #84
* perf(cpu): speed up event systemUri Shaked2021-06-201-25/+47
| | | | | | Use a linked list instead of array. This makes the simulator runs almost twice as fast in case of timers with prescaler of 1, e.g. when using the TVout library. In addition, we use a pool of clock event objects to avoid expensive GCs.
* fix(timer): Timer1 PWM issues #94Uri Shaked2021-06-192-2/+24
| | | | close #94
* fix(twi): broken repeated start #91Uri Shaked2021-04-152-1/+26
| | | | fix #91
* feat(usart): implement RX #11Uri Shaked2021-02-194-7/+99
| | | | close #11
* fix: typo in parameter nameUri Shaked2021-01-023-6/+6
| | | | | freqMHz → freqHz in SPI, TWI, and USART: they all expect the frequency in hertz, not mega-hertz.
* fix(timer): delay() is inaccurate #81Uri Shaked2020-12-292-21/+26
| | | | fix #81
* fix(timer): Output Compare in PWM modes #78Uri Shaked2020-12-276-67/+353

| | | | fix #80

| | | | fix #79
* 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.
