tinygo_machine (package) #

Languages: English | 日本語

Board-agnostic bindings corresponding to TinyGo's machine package (GPIO, ADC, LED).

Following the design principle of not putting board-specific code into the core (packages/dart2tinygo), this package only deals with functionality that TinyGo provides in common. Board-specific bindings live in separate packages (e.g. package:wio_terminal).

import 'dart:io';

import 'package:tinygo_machine/tinygo_machine.dart';

void main() {
  final led = Pin.led..configure(PinMode.output);
  while (true) {
    led.toggle();
    sleep(const Duration(milliseconds: 500));
  }
}

• GPIO: Pin.led (the board's own user LED), Pin(n) (an arbitrary pin number), configure(PinMode.output | PinMode.input) (input uses an internal pull-up), high()/low()/toggle()/get().
• ADC: newAdc(pin) configures a Pin as an analog input; .read() returns the raw 0-65535 sample.
• PWM: newPwm(pin, freqHz) probes every PWM peripheral this chip family exposes (TCC0-4 on atsamd51, PWM0-7 on rp2, ...) for one that can claim the pin — every chip family exposes a different peripheral type with no common shape, unlike GPIO/ADC, so this is real per-chip-family probing rather than a fixed mapping; .setFrequency(freqHz) retunes it (shared by every channel on the same underlying peripheral) and .setDuty(percent) sets the duty cycle (0-100).

See examples/blinky for a full board-agnostic example, buildable for any TinyGo target (tinygo build -target=<board> .).
