* fix(gpio): timer outputs not reflected in PIN register #102Uri Shaked2021-08-132-8/+22
| | | | fix #102
* fix(gpio): PWM may leaves pins in high stateUri Shaked2021-08-091-0/+1
| | | | Disabling PWM when a GPIO pin is high will cause the pin to get stuck in high state.
* style(spi): remove redundant whitespace from commentsUri Shaked2021-08-071-2/+2
|
* feat(usart): add `immediate` parameter to writeByte()Uri Shaked2021-07-171-8/+12
| | | | The value will be available immediately to the user program instead of waiting one symbol time before making it available.
* fix(usart): tx / rx complete timingUri Shaked2021-07-161-1/+1
| | | | fix the calculation of cyclesPerChar, which is used to determine when a USART RX/TX operation is marked complete.

| | | | 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.

| | | | 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 Shaked2020-12-273-59/+325
| | | | close #78
* fix(timer): Overflow interrupt fires twice #80Uri Shaked2020-12-262-7/+45
| | | | fix #80
* fix(timer): Output Compare sometimes misses Compare Match #79Uri Shaked2020-12-252-6/+45
| | | | 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
* fix(timer): Incorrect count when stopping a timerUri Shaked2020-12-122-18/+41
| | | | fix #72
* perf!: centeral timekeepingUri Shaked2020-12-0910-211/+173
| | | | | | | | | 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.

* feat(timer): Compare Match Output (#45)Uri Shaked2020-05-253-57/+338
| | | | | The Compare Match Output bits are used to generate hardware PWM signals on selected MCU pins. This is also the mechanism used by Arduino's analogWrite() method. See #32 for more details

| | | | | | According to the datasheet, the value of the high byte of the counter for 16-bit timers (such as timer 1) is only updated when the low byte is being read/written. close #37
