2021-07-16fix(usart): tx / rx complete timingUri Shaked1-1/+1
fix the calculation of cyclesPerChar, which is used to determine when a USART RX/TX operation is marked complete.
2021-07-15feat(usart): add configuration change eventUri Shaked2-3/+95
also add `txEnable` and `rxEnable` properties
2021-07-07fix(timer): only set ICR hook for 16-bit timersUri Shaked1-3/+3
The ICR (Input Capture Register) only exists for 16-bit timers.
2021-07-07feat(gpio): external interrupt/PCINT support (#82)Uri Shaked4-18/+459
close #70, #84
2021-06-20perf(cpu): speed up event systemUri Shaked1-25/+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.
2021-06-19fix(timer): Timer1 PWM issues #94Uri Shaked2-2/+24
close #94
2021-04-15fix(twi): broken repeated start #91Uri Shaked2-1/+26
fix #91
2021-02-19feat(usart): implement RX #11Uri Shaked4-7/+99
close #11
2021-01-02fix: typo in parameter nameUri Shaked3-6/+6
freqMHz → freqHz in SPI, TWI, and USART: they all expect the frequency in hertz, not mega-hertz.
2020-12-29fix(timer): delay() is inaccurate #81Uri Shaked2-21/+26
fix #81
2020-12-27fix(timer): Output Compare in PWM modes #78Uri Shaked6-67/+353

fix #80

fix #79
2020-12-21fix(timer): Output Compare issue #74Uri Shaked2-10/+28
output compare doesn't work when the OCR register (OCRnA/OCRnB) equals to 0 fix #74
2020-12-20fix(timer): TOV flag does not update correctly #75Uri Shaked2-20/+56
fix #75
2020-12-20fix(timer): OCR values should be buffered #76Uri Shaked2-11/+125
fix #76
2020-12-12perf(cpu): speed up event systemUri Shaked2-18/+59
ditch `array.sort()` and instead manually keep the array sorted when we insert a new item.
2020-12-12test(cpu): fix implicit any errorUri Shaked1-3/+5
2020-12-12fix(cpu): event system issueUri Shaked2-2/+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.
2020-12-12fix(timer): Incorrect count when stopping a timerUri Shaked2-18/+41
fix #72
2020-12-09perf!: centeral timekeepingUri Shaked12-221/+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.
