mbed_example / Mbed 2 deprecated AnalogOut_HelloWorld_mbed

Dependencies:   mbed

Use

The AnalogOut API is used to convert a digital number to an analog value. The output value is set as a percentage of the supply voltage. The percentage is specified as a floating point number between 0 to 1. This example demonstrates a ramp from 0 to 1 in 10% increments.

Note

Not all boards support analog output. The board must have a Digital to Analog Converter (DAC) to use the API. The compiler will throw a warning if the AnalogOut API is not available for a target board. Alternatively the target platform will list its components on the Platforms page.
