# THIS IS A SLIGHTLY HACKY EXAMPLE PROJECT DESIGNED TO HELP YOU TOWARDS INCLUDING THE PICO SDK
|
|
# CODE OUTSIDE OF THE CMAKE BUILD
|
|
#
|
|
# Note that the Pico SDK is designed to make it easy for users to build applications rather to build
|
|
# other runtimes for the Pico.
|
|
#
|
|
# There is no included "static library" of the Pico SDK because all of the Pico SDK Libraries are configurable
|
|
# on a per binary basis, and are always compiled from scratch per binary within the normal Pico SDK CMake build
|
|
#
|
|
# Note you would want to customize this to add or remove the dependencies you want (e.g. you mau not want
|
|
# to depend on pico_stdlib, but rather pick and mix some of its constituents to give you a finer grain of control
|
|
#
|
|
# Note that this example produces a build_info.txt in the output with some approximate (we're not trying to
|
|
# rewrite CMake here!) compile and link flags based on the setup of your static_sdk library
|
|
#
|
|
# Finally note that even copying the build and link flags from build_info.txt and linking against the generated
|
|
# library does not get you all the way, as you still need a second stage boot at the start of the binary (0x000-0x100)
