Description of example project
|
|
==============================
|
|
This example project depicts usage of DAC drivers.
|
|
|
|
Hardware Setup
|
|
===============
|
|
XMC4500 Hexagon board / XMC4500 Relax Kit
|
|
This example demonstrate two of five DAC configurations. It generates an analog sine
|
|
wave on DAC0 Output and a static analog value on DAC1 Output.
|
|
e.g. XMC44/45 P14.8 (DAC0), P14.9 (DAC1)
|
|
|
|
How to test the application
|
|
============================
|
|
To change the frequency and amplitude the function DAC_Update() is called
|
|
periodical. DAC_Update() only has to be called to change frequency or
|
|
amplitude not for basic sine wave generation.
|
|
|
|
The value in beats[index] defines after how many function calls
|
|
the frequency and amplitude will be updated. The value in melody[index]
|
|
defines the new frequency and if the amplitude have to be set to minimum.
