The components are configured by right clicking on the component in your Top Design schematic view and selecting Configure. Please enable the following selections in the Configuration windows for the listed components above.
Firmware Description:
The main.c firmware is included in the example project. Please review the commented sections for more details.
In this example we expand on our earlier example. We have developed another custom component to interface with the MP3 codec board over the SPI interface.
