No-OS Supported Examples

The initialization data used in the examples is taken out from: Project Common Data Path

The macros used in Common Data are defined in platform specific files found in: Project Platform Configuration Path

Basic example

This is a simple example which initializes the max14919 and sets the output channel 2 on, after which is detects faults, reverse polarity and sets 2x current limit for the device.

In order to build the basic example make sure you have the following configuration in the Makefile Makefile

# Select the example you want to enable by choosing y for enabling and n for disabling
BASIC_EXAMPLE = y
