Description

The Analog Output block sends an analog signal to the DAC0_OUT pin that is on the board.

When you provide a value between 0–1, this block outputs an analog signal to the DAC0_OUT pin, such that:

Vout = Vref *[(1+(input*4095))/4096]

Vref is the reference voltage for the DAC that you select from Configuration Parameters > Hardware Implementation pane > DAC > DAC0 reference voltage.

Make sure to use only one Analog Output block within the same model.

Ports

Input

Port_1 — Input signal

scalar

The block accepts values between 0 and +1.

When you provide a value between 0–1, this block outputs an analog signal to the DAC0_OUT pin, such that:

Vout = Vref *[(1+(input*4095))/4096]

Vref is the reference voltage for the DAC that you select from Configuration Parameters > Hardware Implementation pane > DAC > DAC0 reference voltage.

Data Types: single | double

Parameters

Sample time — How often to read value from the input port

0.1 (default)

Specify how often this block reads the value from the input port, in seconds.

When you specify this parameter as-1, Simulink® determines the best sample time for the block based on the block context within the model.
