PIC32-HBI PROJECT FOLDER
The PIC32 project folder contains the sample code that enables the LAN9252's HBI
interface to communicate with the SoC. HBI demo code is provided for each of the
LAN9252’s six HBI configurations. These configurations can be selected respectively
from the configuration drop down box as shown in Figure 3-4.
