Description

The Analog Output block generates voltage on the specified DAC pin of the board.

You can run a Simulink^® model containing Analog Output block in Connected IO mode on Arduino^® boards.

Supported Arduino Boards

• Arduino Due

• Arduino Nano 33 BLE Sense

• Arduino MKR 1000

• Arduino MKR Zero

• Arduino MKR Wi-Fi^® 1010

• Arduino Nano 33 IoT

• Arduino compatible ESP32 – WROOM and ESP32 – WROVER

• Arduino Uno R4 Wi-Fi

• Arduino Uno R4 Minima

The block outputs voltage (Vout) on the DAC pin, such that:

Vout = VrefX(input/2N-1)+ Voffset

This table explains the variables in the formula.
