The example also provides a simple summing example, where all 7 microphones
are summed into
output[0]
with the original microphone signals output to
output[1..7]
. This functionality is enabled and disabled using Button A.
6.7.6 Validated Build Options
The reference design can be built in several ways by changing the build options.
These are described in §
7.1 .
The design has only been fully validated against the build options as set in the
application as distributed in the Makefile. See § 5.3 for details and binary naming
schemes.
These fully validated build configurations are enumerated in the supplied Makefile
In practise, due to the similarities between the U/L/xCORE-200 Series feature set,
it is fully expected that all listed U-Series configurations will operate as expected
on the L-Series and vice versa.
The build configuration naming scheme employed in the makefile is as follows:
Feature Option 1 Option 2
Audio Class 1 2
Input enabled: i (channel count) disabled: x
Output enabled: i (channel count) disabled: x

scheme
e.g. A build config named 2i8o2 would signify: Audio class 2.0, input and output
enabled (8 in, 2 out).
