Missing waitFor implementation in _STM32GpioInputPin produces a warning #506

Closed sgjesse closed 8 years ago

sgjesse commented 8 years ago

Running the following code

import 'package:stm32/stm32f746g_disco.dart';

main() {
  var board = new STM32F746GDiscovery();
  var led1 = board.gpio.initOutput(STM32F746GDiscovery.LED1);
  var button1 = board.gpio.initInput(STM32F746GDiscovery.Button1);
  while (true) {
    led1.state = button1.state;
  }
 }

produces this warning:
