QEMU emulated Arduino board visualizer.

The QEMU emulated Arduino board visualizer is a platform for QEMU based board emulation interfacing.


Using the inteface a board is defined as a group of *widgets* connected to the Ardunio. Each widget is defined as a block that can have two features:

  • User interaction: the user can modify the parameters of the widget.
  • Visualization: the widget will show updates of the state of the circuit.

Widgets

Led with brightness widget.
 Led with brightness: the widget indicates the brightness of the led.
  • If the led is connected to a GPIO pin the brightness could be full brightness or none depending on the GPIO state.
  • If the led is connected to a PWM pin the brightness will be proportional to duty cicle of the signal.
 Apple
Potentiometer widget.
 Potentiometer: the widget modifies the middle point of the potentiometer configuring a variable voltage to the ADC.
Switch widget.
 Switch: the widget will be used to turn on/off all the board. The state of the switch is represented with a colored box with text:
  • Open: Green.
  • Closed: Red.
Serial console widget.
 Serial console: the widget will show the updated serial output.
Button widget.
 Button: the widget could be modify by the user. While the button is pressed the pin is connected to GND and HiZ when not.
Oscilloscope widget.
 Oscilloscope: the widget could be connected to any pin showing the updated signal generated by QEMU.
